bloc

问题 I have two BLoCs. EstateBloc EstateTryBloc My Application basically gets estates from an API and displays them in a similar fashion Now I wanted to add a sort functionality, but I could only access the List of Estates via a specific state. if(currentState is PostLoadedState){{ print(currentState.estates); } I wanted to make the List of estates available for whichever bloc, that needed that list. What I did was, I created the EstateTryBloc, which basically contains the List of estates as a

问题 I'm trying to create a BlocListener that has the ability to listen to all pages/routes throughout the app just like how you can access a Bloc or a Provider all throughout the app if they are defined at root-level like in the code below runApp( MultiProvider( providers: [ ChangeNotifierProvider<IdentityTokenProvider>( create: (_) => IdentityTokenProvider(), ), ], child: MultiBlocProvider( providers: [ BlocProvider<AuthBloc>( create: (_) => AuthBloc(), ), ], child: MaterialApp(

问题 I would like download the data, but also use the application all the time. Can you tell me if it's right solution? The case is we press button download and call funtion bloc.dispatch(Event.download()); In mapEventToState in _Download event we reqest data. But we don't wait for response because we don't want to block others events which are changing view. So I create Future and after getting response I call event _UpdateData() where I process downloaded data and generate state with them. It's

问题 I'm facing issue in my current project so created this question im unable to get same bloc state in other widget i tried this https://github.com/felangel/bloc/issues/74#issuecomment-457968962 but i'm getting BlocProvider.of() called with a context that does not contain a Bloc of type CounterBloc. error if add Provider again in other widget another state is created for that page how to use same bloc state in different widgets. import 'dart:async'; import 'package:flutter/material.dart'; import

问题 I was looking into quite a few pages to learn how to best implement an app wide bloc (for authentication, user management and initialization). I did not find so much and for a beginner regarding this level of bloc patterns I found it hard to identify a reasonable one. The pattern by Didier Boelens explained here appears to be the most promising one. Is it still a sound pattern (it is from 2018) or did the bloc library evolve in the meantime or did other patterns proved better/easier? What

问题 I have a dashboard , represented by grid, that supposed to delete item on long press event (using flutter_bloc), but it deletes last item instead of selected. All debug prints show, that needed element actually removed from list, but view layer still keeps it. My build function code: Widget build(BuildContext context) { double pyxelRatio = MediaQuery.of(context).devicePixelRatio; double width = MediaQuery.of(context).size.width * pyxelRatio; return BlocProvider( bloc: _bloc, child:
