On load: Concurrent modification during iteration: Instance(length:3) of '_GrowableList'.

void main() async{

final persistor = Persistor( storage: FlutterStorage(key: "GMWAN_AppState.json", location: FlutterSaveLocation.sharedPreferences), // Or use other engines serializer: JsonSerializer(GMWAN_AppState.fromJson), // Or use other serializers );

// Load initial state /*

final initalStateCompleter = Completer();

persistor.load().then((store){ initalStateCompleter.complete(store); }).catchError((c){ print('ERRRRROOOOOORRRRRRR--------------------------------------------'); initalStateCompleter.complete(GMWAN_AppState(userState: ParticleUserState(user: ParticleUser.notLoggedIn()),infoCardsState: InfoCardsState())); });

*/

final initialState = await persistor.load();

final store = new Store( appStateReducer, initialState: initialState ?? GMWAN_AppState(userState: ParticleUserState(user: ParticleUser.notLoggedIn()),infoCardsState: InfoCardsState()), middleware: [thunkMiddleware, persistor.createMiddleware()]);

runApp(StoreProvider( child: MyApp(), store: store, )); }

Above is my main method. The thunk middle ware is an async network call that builds a list on response.

This seems to happen because you are calling load twice. Try with just one
