Actually This is a warning. Better you should define a class MyApp and call this class under runApp. Example: void main() { runApp(MyApp()); }
class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', debugShowCheckedModeBanner: false, theme: ThemeData( scaffoldBackgroundColor: Color(0xff1f1f1f), primarySwatch: Colors.blue, ),
I think this may solve this warning.
When we create a flutter project, by default flutter create a test folder that contains widget_test.dart. Inside that, the pumpWidget method requires a widget to build our app and trigger a frame. It is not necessary but can be used for widget testing purposes. By default, it takes a widget named MyApp which is the first root widget that flutter creates for you. I assume that you might have removed the boilerplate code, which in turn removed that widget. You can either provide the name of the root widget(the widget given to the runApp method) as an argument to that method or create a widget named MyApp which is the root widget. You can also just ignore the warning or delete the folder widget_test.dart.
