When I get app then it show error.

======== Exception caught by foundation library ====================================================
The following assertion was thrown while dispatching notifications for FeedProvider:
setState() or markNeedsBuild() called during build.

This _DefaultInheritedProviderScope widget cannot be marked as needing to build because the framework is already in the process of building widgets. A widget can be marked as needing to be built during the build phase only if one of its ancestors is currently building. This exception is allowed because the framework builds parent widgets before children, which means a dirty descendant will always be built. Otherwise, the framework might not visit this widget during this build phase.
The widget on which setState() or markNeedsBuild() was called was: _DefaultInheritedProviderScope
value: Instance of 'FeedProvider'
listening to value
The widget which was currently being built when the offending call was made was: BlocBuilder<NewsFeedBloc, NewsFeedState>
dirty
state: _BlocBuilderBaseState<NewsFeedBloc, NewsFeedState>#b5032
When the exception was thrown, this was the stack:
#0 Element.markNeedsBuild. (package:flutter/src/widgets/framework.dart:4328:11)
#1 Element.markNeedsBuild (package:flutter/src/widgets/framework.dart:4343:6)
#2 _InheritedProviderScopeMixin.markNeedsNotifyDependents (package:provider/src/inherited_provider.dart:269:5)
#3 ChangeNotifier.notifyListeners (package:flutter/src/foundation/change_notifier.dart:243:25)
#4 FeedProvider.setDataLoaded (package:inshort_clone/controller/provider.dart:68:5)
...
The FeedProvider sending notification was: Instance of 'FeedProvider'

The name 'Router' is defined in the libraries 'package:flutter/src/widgets/router.dart' and 'package:inshort_clone/routes/routesgr.dart'.
Try using 'as prefix' for one of the import directives, or hiding the name from all but one of the imports.

Description: The app has many deprecated members like List , cursorColor and WatchBoxBuilder which can be fixed by updating them

Why you are comment all Router usage line?
For example if we want to open the setting page right now it not work bcz you comment the relative code in the source.

Description: This Issue is for creating a login screen so to deal with user management and Initialize Firebase for the app

Description: This fix would help in easier readability of the code and also help in easier debugging wherever necessary

Future Work: If approved, these can also be implemented

• https://pub.dev/packages/pedantic
• https://pub.dev/packages/dart_code_metrics

May I know how to change the news to any particular region i.e. Pakistan using the newsapi.org APIs?

Top Appbar not working in release Apk, it works fine in debug Apk. I think the problem in Stream Controller which I used for page transition.
I'll fix this issue soon.

Hi guys,
On the real device the appbar not appear and it cause below exception:

Hi there,

I am new to app building and the software world. I know how to code and all but haven't tried end-to-end yet. Can you pls tell me how and where I can run this so that I can get started in doing some edits of my own?
