Unbounded as top-level tab on the home screen (Part 2/2)

[myleshorton]

Summary

Adds Unbounded as a top-level tab at the top of the home screen — its own surface alongside the VPN tab, distinct from the unified Share My Connection screen shipped in [Part 1].

Where the SmC screen is opt-in, settings-buried, explicit-disclosure (the user actively chooses to be a peer), the Unbounded tab is visible, auto-enabled, low-friction (Unbounded contributes by default once the server-side flag is on, with an easy hide-tab opt-out). The two surfaces share the same underlying broflake widget-proxy in radiance — this PR is purely about exposing it as a top-level surface and shaping the auto-enable behavior.

This is Part 2 of 2 of the original #8740 split, stacked on Part 1 ([8740-B]).

What's in this PR

Tab surface (Phases 1–4):

• Phase 1 — Tab shell. Unbounded added as a top-level tab alongside VPN. Visible on every supported Lantern platform (desktop + Android + iOS) once the server flag is on; the hide-tab toggle in Settings covers the per-user opt-out.
• Phase 2 — Settings sheet + hide-tab toggle. Users who don't want the tab visible can hide it via Settings.
• Phase 3 — Auto-enable on VPN connect. First time the user connects to VPN, Unbounded auto-enables (mediated by a "has the user opted out" check).
• Phase 4 — First-visit welcome popup + info bubble. One-shot, with persistence so it doesn't reappear.

Auto-enable refinement:

• Auto-enable on app launch as well, not just on VPN connect — covers the case where Unbounded was active and the user restarts the app.

Visual polish:

• Heart-spray (Lottie) for remote-client arrivals, iterated from inside-the-pill → overflowing-pill → on-globe; landed on "on-globe with floating toast" matching the SmC screen.
• "Total people helped to date" counter, persisted across restarts so users see cumulative impact.

Server gating:

• Entire Unbounded UI surface (tab, settings entry, auto-enable hooks, project link) is gated on the server-side Features[unbounded] flag. When false (the default for censored regions) the tab and all associated UI disappear — censored users should never see a "share your connection" surface that could draw on-device attention.

SmC → Unbounded fallback:

• If peer.Client.Start fails for any reason (UPnP denied, port collision, lantern-cloud unreachable), the SmC screen auto-falls back to Unbounded mode. User sees a "trying Basic mode instead" notice rather than a hard error.

Final SmC polish:

• Lottie heart-burst rendered at native canvas size (was being downscaled).
• Heart-to-text gap nudged 10 → 14 px to match design.

How this was sliced

Cherry-picked from the original fisk/share-my-connection-ux (#8740) — chronological commits 22 through 35, stacked on top of [8740-B]'s 21 commits. Reviewers see the Unbounded-tab-specific diff only.

Why both surfaces (tab + SmC screen)

The unified SmC screen is for users who want to think about being a peer; it makes the act explicit and gives them controls. The Unbounded tab is the low-friction, default-on path for everyone else — it's Unbounded contributing in the background with an easy way to turn it off. Different products serving different segments of the user base.

Reconciling the two surfaces is a follow-up product decision (does turning Unbounded off in one place turn it off in the other? does the SmC screen "Basic mode" pick stick across visits to the tab?). For MVP, both ship, and operations are independent.

Test plan

• flutter analyze clean.
• go build ./lantern-core/... clean.
• macOS end-to-end:
  • Open app → Unbounded tab present at top of home (with feature flag on).
  • Auto-enable on first VPN connect → broflake widget proxy starts running.
  • Restart app → Unbounded re-enables on launch.
  • Hide tab via Settings → tab disappears from home.
  • Toggle server-side Features[unbounded] off → entire Unbounded UI surface disappears (tab, settings entry, auto-enable disabled).
  • SmC screen + Unbounded tab both visible → confirm they don't fight each other when toggled.
• Fallback path: force peer.Client.Start to fail (e.g., block UPnP) → SmC screen toggles to "trying Basic mode instead", broflake takes over.

Pull request overview

Part 2/2 of the Unbounded UX split: lifts Unbounded from the buried Share-My-Connection screen onto its own top-level Home tab, adds a Settings sub-page (auto-enable + hide-tab), a one-shot welcome dialog, a persisted lifetime "people helped" counter, and a transparent SmC→Unbounded fallback when peer.Client.Start errors. Gated end-to-end on the server-side Features[unbounded] flag.

Changes:

• Refactor Home into a two-tab shell (VPN + Unbounded) with status-dot tab labels; lift VPN body into vpn_tab.dart.
• Add UnboundedSetting page + appSettingProvider fields (unboundedAutoEnable, unboundedHidden, unboundedWelcomeSeen, unboundedTotalHelped) and wire auto-enable on app launch and VPN-connect.
• Rework the share screen body into UnboundedTab with persisted total counter, "Waiting for connections…" idle pill, full-canvas Lottie heart-burst, info bubble + welcome dialog, and a _handlePeerStatus-driven SmC→Unbounded fallback path.

Re-analyzed and I think the inner guard in autoStart already handles this. Trace:

useEffect's postFrameCallback fires (or microtask, whichever first)
  → caller-side guard reads share (false, false) → passes
  → calls autoStart UNAWAITED (autoStart returns a Future)
  → autoStart's first statement: 'if (state.active || state.probing) return;' → passes
  → next statement (synchronous): 'state = state.copyWith(probing: true);'
  → first await ('_start' eventually awaits PatchSettings) → yields control
Now the OTHER scheduler fires:
  → caller-side guard reads share (false, TRUE now) → bails
  → never even calls autoStart

Dart isolates are single-threaded — there's no preemption between autoStart's guard and the probing=true set; they run synchronously in the same microtask hop. The only way both would pass is if there's a yield between them, and there isn't.

That said, the combined fix from #3321840455 (autoStart now does a single unconditional _start(unbounded) rather than mixing manual-port lookup + probe + mode selection) further shortens the synchronous prefix, so even hypothetical scheduling oddities have less room to interleave. Going to leave the home.dart caller-side guards as-is; happy to consolidate into a single helper in a follow-up if the dual-entry-point pattern grows.

[myleshorton]

Pushing back: the empty deps list is intentional, not an oversight.

The welcome dialog is a once-per-device first-visit primer (persisted via appSettingProvider.unboundedWelcomeSeen). The design contract is:

1. First visit on a clean install → dialog auto-fires once.
2. Re-openable anytime via the info-bubble icon (already wired).
3. Sign-out + sign-in or settings reset → flag clears → next launch fires the dialog again on next Home mount.

What the dialog explicitly should NOT do: re-fire WITHIN the same Home lifetime when the flag is reset programmatically (e.g. user opens it via the info bubble, the whenComplete sets seen=true, but if they immediately reset settings via a debug menu, we don't want the dialog to pop again in the same session — that would be jarring).

The current shape (useEffect(..., const []) + read on mount) gives exactly that. Watching the provider would re-fire the dialog when the flag transitioned from true→false within the same lifetime, which isn't desired.

If a future design wants the dialog to re-fire on sign-out within the same session, the right place would be the sign-out handler itself (push a Navigator route or similar), not the welcome-dialog useEffect.

• The autoStart docstring says it’s used by an “Auto-enable Unbounded” Settings toggle, but autoStart is only invoked from Home (search shows no other call sites). This comment is misleading and makes it harder to understand the actual contract (programmatic start initiated by Home’s VPN/app-launch listeners).

• The documentation for unboundedAutoEnable is internally inconsistent: this comment says it “defaults on”, but the constructor default is false (line 36) and fromJson treats missing/unset as disabled (opt-in). This also affects the PR’s stated “auto-enabled by default” behavior—please align the intended default/semantics (opt-in vs opt-out) across docs and initialization.

  // Unbounded preferences. autoEnable: turn the peer share on whenever
  // the VPN connects (defaults on per the Figma spec). hideTab: hide

• UnboundedTabVisible.set always assigns state = visible even when the value is unchanged. Home’s TabController listener can call this repeatedly during animation ticks, which can trigger redundant provider notifications/rebuilds and undermine the globe CPU-saving work. Guard against no-op updates.

• peerLookup interpolates the raw IP into the URL path without encoding. This can break lookups for IPv6 addresses (colons) or other non-path-safe forms (e.g., scoped IPv6 with %), leading to repeated PeerGeo.unknown and missing arcs/toasts for those peers.

1504-1523: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The waiting card appears while sharing is off.

_ArrivalToast renders inside the globe stack unconditionally. Its only inputs are _current and activeCount. When the user has not enabled sharing, _current is null and activeCount is 0, so the widget shows unbounded_waiting_for_connections.

The status card directly below then reports smc_status_off. The two statements contradict each other. Nothing is waiting for connections, because nothing is running.

Gate the waiting card on the active state.

🐛 Proposed fix

-    final hasPeers = ref.watch(shareProvider).activeCount > 0;
+    final shareState = ref.watch(shareProvider);
+    // Only claim we are waiting when sharing is actually running.
+    final showWaiting = shareState.active && shareState.activeCount == 0;

       child: event == null
-          ? (hasPeers
-              ? const SizedBox.shrink(key: ValueKey('arrival-idle'))
-              : const _WaitingCard(key: ValueKey('arrival-waiting')))
+          ? (showWaiting
+              ? const _WaitingCard(key: ValueKey('arrival-waiting'))

313-351: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

A toggle-off during the UPnP probe is silently reverted.

Line 313 sets probing: true. The manual-port read and probeUPnP then block for up to about six seconds. During that window the switch is live, and _StatusCard routes a tap to toggle, which takes the state.probing branch and runs _stop.

_stop resets the state to off. The original toggle call is still suspended on probeUPnP. When it resumes, it calls _start unconditionally. Sharing turns on after the user turned it off.

The recheck at Line 311 covers only the consent-dialog window, not the probe window. Add a generation guard that the awaits are validated against.

🐛 Proposed fix

Add a field to ShareNotifier:

// Bumped by every _stop / toggle entry so an in-flight probe can detect
// that the user cancelled while it was blocked.
int _toggleGen = 0;

Bump it in _stop:

  Future<void> _stop(WidgetRef widgetRef) async {
    _toggleGen++;
    _stopEventSubscription();

Then guard each resume point:

     state = state.copyWith(probing: true);
+    final gen = _toggleGen;
 
     if (PlatformUtils.isIOS) {
+      if (gen != _toggleGen) return;
       await _start(widgetRef, ShareMode.unbounded);
       return;
     }
 
     final manualPortRes =
         await widgetRef.read(lanternServiceProvider).getPeerManualPort();
     final manualPort = manualPortRes.fold((_) => 0, (p) => p);
+    if (gen != _toggleGen) return;
     if (manualPort > 0) {
       await _start(widgetRef, ShareMode.smc);
       return;
     }
 
     final probeRes =
         await widgetRef.read(lanternServiceProvider).probeUPnP();
     final upnpAvailable = probeRes.fold((_) => false, (v) => v);
+    if (gen != _toggleGen) return;
     if (!upnpAvailable) {
       await _start(widgetRef, ShareMode.unbounded);
       return;
     }
 
     await _start(widgetRef, ShareMode.smc);

The fixed-height children can overflow the column at large text scales.

Only the globe is flexible. The info card, _StatusCard, and _AutoEnableCard all size to their content. When sharing is active, _StatusCard adds two _StatRow children. When the user raises the system text scale, every text-driven child grows, Expanded collapses the globe to zero, and the remaining fixed children exceed the available height. Flutter then reports a RenderFlex overflow.

Make the column scrollable and give the globe a bounded height.

A steady arrival rate keeps the focus animation running continuously.

The comment states that the turn is "a brief, finite animation that settles back to static (no continuous cost)". That holds for an isolated arrival. An active donor receives arrivals continuously, and each one starts a new 900 ms turn. Arrivals more frequent than 900 ms apart keep the globe animating without pause, which restores the per-frame full-sphere repaint that dashAnimateTime: 0 and desktop-only rotation were added to avoid.

Consider skipping the focus turn when one is already in flight, or rate-limiting it.

The status dot conveys state through color only.

The dot at Lines 324-335 switches between AppColors.green6 and AppColors.gray5 to signal whether the feature is running. A screen reader announces only the label text, so a non-sighted user cannot tell whether the VPN or Unbounded is active from this tab. Users who cannot distinguish the two hues have the same problem.

Wrap the dot in a Semantics node with a state label, and pass the state through from Home.

Replace the disabled IconButton chevrons with a plain image.

Both blocks build an IconButton with onPressed: null. That marks the button as disabled. Flutter then exposes it to the accessibility tree as a disabled button and applies the disabled foreground color, while the actual tap target is the enclosing SettingTile.onTap. A screen reader user hears a disabled control that is not the real control.

The two blocks are also byte-identical, which duplicates 12 lines.

Use the bare AppImage as the trailing decoration.

Use list literals instead of set literals in the spreads.

...{ ... } builds a Set<Widget> and then spreads it. A Set drops duplicate elements. Const widgets are canonicalized, so two identical const DividerSpace() entries in one set literal would collapse into one and a divider would silently disappear.

The current sets each hold distinct elements, so behavior is correct today. The hazard appears the moment someone adds a second identical const child. The same pattern repeats at Lines 87-107 and Lines 108-130. Change all three to ...[ ... ].

Remove the duplicate turn_on_vpn entry.

msgid "turn_on_vpn" is already defined at Lines 815-816 with the same msgstr. A .po file must not contain the same msgid twice. msgfmt reports a duplicate-message-definition error, and translation platforms either reject the import or silently keep only one entry.

Delete the new block and keep the existing definition.

Correct the stale comment: auto-enable defaults off, and two field names are wrong.

The comment states auto-enable "defaults on per the Figma spec". The constructor at Line 36 sets unboundedAutoEnable = false, and the fromJson comment at Lines 105-107 states the opposite ("Opt-in ... default off"). The comment also names autoEnable, hideTab, and welcomeSeen; the declared fields are unboundedAutoEnable, unboundedHidden, and unboundedWelcomeSeen. hideTab does not exist.

This default controls whether the device shares its connection without an explicit user action. Keep the documentation unambiguous.

📝 Proposed comment fix

-  // Unbounded preferences. autoEnable: turn the peer share on whenever
-  // the VPN connects (defaults on per the Figma spec). hideTab: hide
-  // the Unbounded tab + collapse the tab bar when the user doesn't

Enforce the Unbounded feature gate for direct navigation.

UnboundedSetting does not check FeatureFlag.unbounded, and its route has no guard. A direct appRouter.push(UnboundedSetting()) bypasses the hidden settings entry. Add a route guard or destination-level check that blocks access when the flag is false.

Both lookups accept 0/0 as a valid coordinate. The new parsing tests Location.Latitude and Location.Longitude with != null. The geo service marshals a Go MaxMind record, so an absent or unresolved location still emits both fields with the value 0. The null test passes, the country-centre fallback never runs, and the point lands in the Gulf of Guinea.

Post-frame callbacks in Home read providers without a disposal check. The conversion from StatefulHookConsumerWidget to HookConsumerWidget moved these side effects into useEffect bodies that schedule addPostFrameCallback.

Hiding Unbounded does not stop an active share.

setUnboundedHidden only writes the preference. It does not touch shareProvider.

Consider this sequence: sharing is active, and the user enables "Hide Unbounded". Home sets showUnboundedTab to false at Line 103 and renders const VpnTab() instead of the TabBarView. The Unbounded tab, its status card, and its toggle all disappear. The peer share keeps running. Third-party traffic continues to route through the user's connection, and the user has no visible control to stop it.

The comment in lib/features/home/home.dart at Lines 157-162 states that hiding is the opt-out and that a user who hid Unbounded "should not see it silently auto-enable in the background". The current behavior contradicts that intent for an already-running share.

Either stop the share when the user hides the tab, or keep a stop control reachable from this settings screen.

🛡️ Proposed fix — stop sharing when the tab is hidden

+  Future<void> _setHidden(BuildContext context, WidgetRef ref, bool hidden) async {
+    ref.read(appSettingProvider.notifier).setUnboundedHidden(hidden);
+    if (!hidden) return;
+    // Hiding removes the only stop control, so do not leave the share running.
+    final share = ref.read(shareProvider);
+    if (share.active || share.probing) {
+      await ref.read(shareProvider.notifier).stop();
+    }
+  }

Then wire both entry points:

                   trailing: SwitchButton(
                     value: hidden,
-                    onChanged: notifier.setUnboundedHidden,
+                    onChanged: (v) => _setHidden(context, ref, v),
                   ),
-                  onPressed: () => notifier.setUnboundedHidden(!hidden),
+                  onPressed: () => _setHidden(context, ref, !hidden),

Confirm the stop method name on ShareNotifier before applying.

Riverpod 3 WidgetRef read after widget disposed _assertNotDisposed Cannot use ref after widget was disposed

💡 Result:

The error "Cannot use ref after widget was disposed" (or similar variations) indicates that a WidgetRef or Ref was accessed after the component or provider it belongs to has been unmounted or destroyed [1][2][3]. In Riverpod 3.0, the framework has become stricter; while some edge cases previously allowed interaction with disposed refs, Riverpod 3.0 explicitly throws an UnmountedRefException (or similar "Bad state" errors) to prevent silent bugs and state corruption [4][5][6]. Common Causes and Fixes: 1. Asynchronous Gaps: This frequently happens after an await statement [1][3]. If a widget navigates away or a provider is disposed while an asynchronous operation is pending, any subsequent ref.read or ref.watch call will trigger the error [1][3]. - Fix: Read all necessary values from ref synchronously before the await [3]. - Fix: Guard post-await code with a "mounted" check. For widgets, use if (!context.mounted) return; [1][2]. For providers/notifiers, use if (!ref.mounted) return; [4][6][3]. 2. Using Ref in Dispose: Attempting to use ref inside a dispose() method is inherently unsafe, as the widget's element tree is already in the process of being torn down [3][7]. - Fix: Perform any necessary cleanup (e.g., cancelling subscriptions, notifying other providers) within the provider's ref.onDispose callback instead of the widget's dispose() method [8][3]. 3. Provider Life-Cycle: In Riverpod 3.0, if a provider is recomputed or disposed, its associated Ref becomes invalid immediately [4][6]. - Fix: Ensure async operations are cancellable. Use ref.onDispose to cancel pending work (like HTTP requests) to ensure they do not attempt to interact with a dead Ref upon completion [8][9]. General Best Practice: - Avoid holding onto ref beyond the scope where it is valid [3]. - Prefer ref.watch or ref.listen in your UI over ref.read when possible, as these create proper dependency relationships that better handle provider lifecycles [9][10]. - If you find yourself needing to keep a provider alive during an async operation, consider using ref.keepAlive() (if using autoDispose) or structuring your logic to be more resilient to provider disposal [5][9][11]. For more detailed debugging, check the official Riverpod migration guide and FAQ, which specifically address these behavioral changes in v3.0 [4][1].

Do not capture WidgetRef in the event callback.

A delayed phase=error event can call read after the originating widget is disposed. Riverpod 3 throws in this case. Use ShareNotifier’s ref.read(lanternServiceProvider) in _fallbackToUnbounded and remove the WidgetRef parameter from the callback chain.

github.com/getlantern/radiance PeerShareEnabledKey peer StatusEvent phase error

💡 Result:

In the context of the getlantern/radiance repository, PeerShareEnabledKey, StatusEvent, and the peer-sharing (Share My Connection) lifecycle are components used to manage and report the state of the peer-to-peer proxying feature [1][2]. PeerShareEnabledKey PeerShareEnabledKey is a configuration key (a boolean) used to persist the user's preference for whether "Share My Connection" (peer-to-peer proxying) is enabled [1][2]. When this setting is toggled, the application backend (LocalBackend) uses it to trigger the starting or stopping of the peer client [1][2]. StatusEvent and Peer Lifecycle The Radiance backend emits StatusEvent messages to report the lifecycle state of the peer client (e.g., successful start, stop, or errors during initialization) [1]. These events are designed to be consumed by the UI (e.g., via IPC SSE endpoints like /peer/status/events) to provide real-time feedback to the user, such as connection status indicators [1][2]. Phase and Errors The peer-sharing feature involves several operational phases during startup [3]: 1. Registration: The client contacts the server (lantern-cloud) via /v1/peer/register to obtain a configuration [3]. 2. Validation: The client performs validation (e.g., validateAbuseRules) to ensure the server-supplied configuration includes necessary abuse-handling rules and canaries [3]. 3. Execution: If validation passes, the client initializes the sing-box instance [4][3]. 4. Verification: A secondary /peer/verify step is performed after sing-box has successfully started to confirm the peer is reachable and operational [4]. Errors encountered during these phases (such as start failures, missing abuse-handling rules in the configuration, or registration issues) cause the peer-sharing feature to refuse to start [1][3]. These errors are logged by the backend, often surfaced in StatusEvent emissions, and can trigger a rollback of the PeerShareEnabledKey state to ensure the system remains in a safe configuration [1][4][3].

🌐 Web query:

site:github.com/getlantern/radiance "PeerShareEnabledKey"

💡 Result:

PeerShareEnabledKey is a configuration setting key used within the Lantern Radiance software to manage the peer-to-peer sharing feature, specifically related to the "Share My Connection" functionality [1][2]. It is implemented as a boolean setting that determines whether the peer-sharing client is enabled [1]. When toggled, this key triggers backend logic to start, stop, or resume the peer client and manages the associated lifecycle status events [1]. This key is not a public Apple or general-purpose API key but rather an internal implementation detail within the specific context of the Lantern Radiance codebase [1][2].

🌐 Web query:

site:github.com/getlantern/radiance "StatusEvent" "phase=error"

💡 Result:

The StatusEvent with a phase of error appears to be a specific event type within the Radiance project, a technical framework developed by Lantern [1]. In this codebase, StatusEvent is used by the peer.Client module to communicate lifecycle states [2]. Within the Radiance architecture, the peer.Client module emits status events to notify subscribed components of its state transitions [2]. While StatusEvents are typically used to report lifecycle changes like start success or stop completion, the system is designed to propagate errors as part of its operational state [2][3]. Specifically, if a start process fails, the system may report an error status, and developers utilize mechanisms like errors.Join to surface configuration or runtime failures—such as missing abuse-handling rules or network issues—through the event stream [4]. These events are often consumed via Inter-Process Communication (IPC) Server-Sent Events (SSE) or internal pub-sub channels to trigger UI updates or log failures [2][1]. If you are encountering a StatusEvent with a phase of error, it typically indicates that a backend service (such as the peer connection manager) has failed to initialize, validate its configuration, or maintain a required connection, and is reporting this failure to the application's central event bus [2][4][1].

Clear PeerShareEnabledKey before emitting phase=error. Radiance rolls back the setting only after peer.Client.Start returns, but Start emits PhaseError before returning. _fallbackToUnbounded can therefore enable Unbounded while the peer setting is still true. Clear the setting before publishing the error, or explicitly disable it in the fallback path and handle rollback failures.

745, The error fallback can enable Unbounded before Radiance clears
PeerShareEnabledKey. Update the phase-error handling around _handlePeerStatus
and _fallbackToUnbounded so PeerShareEnabledKey is disabled before publishing or
acting on phase=error, or explicitly disable it in _fallbackToUnbounded with

AppColors.blue8 is fixed and reads poorly on the dark theme.

AppColors.blue8 is 0xFF004D57, a dark teal. _StatRow renders the stat value in that colour on Theme.of(context).cardColor. The app supports dark mode — _GlobeViewState._applyTheme switches textures on Brightness.dark. On a dark card the value text has very low contrast against the surface.

Select the colour from the active brightness, as the surrounding code does with hintColor.

The welcome dialog content does not scroll.

ShareConsentDialog wraps its body in a SingleChildScrollView. _UnboundedWelcomeDialog does not. It stacks a logo, a title, and three body paragraphs in a plain Column. In landscape orientation, or at a raised system text scale, the content exceeds the dialog height and Flutter reports an overflow.

Wrap the column in a scroll view, as the consent dialog does.
