[BUG] Error on initialise

djaygier commented 3 months ago

What is the bug?

When starting the app in release mode it gives error, when starting the app in normal debug mode it gives no error. After the error it doesnt go past it, stays white screen.

I/flutter (10302): type 'Null' is not a subtype of type 'List<dynamic>' in type cast I/flutter (10302): #0 BackgroundIsolateBinaryMessenger.ensureInitialized.<anonymous closure> (package:flutter/src/services/_background_isolate_binary_messenger_io.dart:51) I/flutter (10302): #7 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:184) I/flutter (10302): (elided 6 frames from dart:async)

my main function

`void main() async { WidgetsFlutterBinding.ensureInitialized();

try { await FMTCObjectBoxBackend().initialise(); } catch (e) { log(e.toString()); }

try { await EasyLocalization.ensureInitialized(); } catch (e) { log(e.toString()); }

runApp( EasyLocalization( saveLocale: true, supportedLocales: const [ Locale("en", "US"), Locale("nl", "NL"), Locale("es", "ES"), Locale("hu", "HU"), Locale("it", "IT"), Locale("fr", "FR"), Locale("ru", "RU"), Locale("de", "DE"), Locale("pt", "PT"), ], path: "assets/translations", fallbackLocale: const Locale("en", "US"), child: const MyApp(), ), ); }`

How can we reproduce it?

I don't really know why it happens.

Do you have a potential solution?

Find, understand and fix the error.

This looks potentially like a Flutter internal issue, as the issue is thrown here: https://github.com/flutter/flutter/blob/739e3bd0e8358d2bee3141e45ca4be6af91a36dd/packages/flutter/lib/src/services/_background_isolate_binary_messenger_io.dart#L51.

I can't reproduce this obviously, so I would be extremely greatful if you could try this code. Just comment out whatever is in your main.dart file currently, and paste this in, import libraries as necessary, then see what the result is. If it fails, then there's enough evidence here to file a good issue over on the Flutter repo.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  final rootIsolateToken = ServicesBinding.rootIsolateToken ??
      (throw StateError('Unable to retrieve token'));

  await Isolate.spawn(
    _worker,
    rootIsolateToken,
  );
}

void _worker(RootIsolateToken rootIsolateToken) {
  BackgroundIsolateBinaryMessenger.ensureInitialized(rootIsolateToken);
  print('Success');
}
