getBloc<B extends IsolateBlocBase<Object, S>, S> function

IsolateBlocWrapper<S> getBloc<B extends IsolateBlocBase<Object, S>, S>()

Use this function to communicate with IsolateBlocBase in Isolate.

To get bloc in UI Isolate use IsolateBlocProvider which returns IsolateBlocWrapper.

This function works this way:

• waits for user's Initializer function
• looks for created bloc with BlocA type
  • if it finds any, so returns this bloc's IsolateBlocWrapper
  • else it creates a new bloc and adds to the pull of free blocs. So when UI will call create(), it won't create a new bloc but return free bloc from pull.

Throws IsolateManagerUnInitialized if IsolateManager is null.

An example of how to provide Weather bloc to Theme bloc:

void isolatedFunc() {
  register<ThemeBloc, ThemeState>(
    create: () => ThemeBloc(
      weatherBloc: getBloc<WeatherBloc, WeatherState>(),
    ),
  );
}

Implementation

IsolateBlocWrapper<S> getBloc<B extends IsolateBlocBase<Object, S>, S>() {
  final isolateManager = IsolateManager.instance;
  if (isolateManager == null) {
    throw IsolateManagerUnInitialized();
  } else {
    return isolateManager.getBlocWrapper<B, S>();
  }
}
