Fixes isolate error in Flutter 3.3.0

[acoutts]

This is a WIP fix.

1. We need this PR to be merged and a new version of flutter_isolate to be published: Fixing release and obfuscated build issues for flutter 3.x.x rmawatson/flutter_isolate#118
2. Breaking change: everyone must now add the following annotation to any method they pass to IsolateHandler as the callback to execute:

@pragma('vm:entry-point')

Background: dart-lang/sdk#49181 (comment)

Will update the documentation before changing this from a draft.

Please, help me out with the background because I can't see clearly. Will a new version come from flutter_isolate? I'd be rather unwilling to refer to a github repo instead of the normal pub.dev. Or is this just a temporary fix that will be overridden shortly? What's the expected timeline?

(.flutter-plugins-dependencies shouldn't be included, this is just a secondary issue.)

[acoutts]

Yes we need to wait for a new pub release for flutter_isolate, then we can update this package. Nice spot on flutter-plugins-dependencies --- i will fix that when i update this PR once the flutter_isolate package is published.

For now Ieaving this open so others can use my git dependency as a workaround.

[deakjahn]

OK, I'll be on the lookout.

By the way, if we need to decorate the entry point from now on, either mention this in the README or, at least, don't let me forget to do so when we finish this operation. :-)

I am using isolate_handler to use Firestore. It is working in debug mode but not working in release mode. Is this the reason? By the way, flutter_isolate fix was merged 7 days ago but not released.

Hi @acoutts & @deakjahn,
Are you able to use update the PR to use the new release of flutter_isolate 2.0.3 is now available?

rmawatson/flutter_isolate#118

[acoutts]

Back from vacation.
Updated MR to use newly published version.
@deakjahn we are ready for a final review / merge now.

[deakjahn]

@acoutts There's this single file that says it shouldn't be included at all. Could you remove it? Then I'll merge and publish. Thanks.

[deakjahn]

@acoutts I'd be happy to go on with this. :-)

[acoutts]

Done 🙌
