…e.initialize SupabaseClient already accepts `isolate:` and tracks ownership so a caller supplied instance is not disposed with the client, but Supabase.initialize did not pass it through, so a supabase_flutter app could not reach it. YAJsonIsolate was also not exported by any supabase package, which made the existing SupabaseClient parameter unusable without depending on the isolate package directly.

Make the tests prove that Supabase uses the supplied isolate.
The current tests do not distinguish isolate forwarding from creating a separate isolate. Exercise a client operation that records use of the supplied isolate.

I don't see the point of this now when the isolate isn't long-lived...?
The export will be done soon though (the other isolate PR was just merged yesterday.

Closes the remaining item from #1749.
SupabaseClientalready takes anisolate:parameter and already tracksownership —
_hasCustomIsolatekeepsdispose()from disposing an instance itdid not create.
Supabase.initializejust never forwarded it, so asupabase_flutterapp cannot reach the parameter at all.YAJsonIsolatewas also not exported bysupabaseorsupabase_flutter, whichmade the existing
SupabaseClientparameter unusable without adding a directdependency on
yet_another_json_isolate. This exports the type (show YAJsonIsolate) so the public API is callable, and drops three now-redundantimports the analyzer flagged as a result.
Changes
supabase: exportYAJsonIsolate.supabase_flutter:isolate:onSupabase.initialize, threaded toSupabaseClientthrough_init, with dartdoc noting that a supplied instanceis owned by the caller.
isolate is still usable after
Supabase.instance.dispose().Why
Sharing one instance with code outside Supabase, and — for anyone still on the
released
yet_another_json_isolate2.1.1, where a single persistent workerbacks every
functions.invokeand every large postgrest decode — being able tohold and supervise that instance. #1746 makes the second reason far less
pressing once it ships; the first stands on its own.
Verification
flutter analyzeclean on both packages.packages/supabaseandpackages/supabase_fluttertest suites pass.stream_integration_test.dartfails identically before and after this change (it needs a local stack).
