Why does flutter MaterialApp Widget gives the error “not enough required arguments”












0















The MaterialApp flutter widget is giving the error "1 required arguments expected, but 0 found" for the first flutter project available with the flutter sdk. I'm running it on VScode. And here is the code. Thanks in Advance.



class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp( // This line is giving Error at'('
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}

  • Seems odd, have you tried running it from scratch rather than a hot restart if that's an option. Are there any other clues on the lines before/after the error ?

  • Have you potentially defined another class with the name MaterialApp?

  • Nope, there is no other Widget named after that. Moreover, its the flutter code which you get after starting a new flutter project made by the flutter team for beginners. And I have also tried re-installing the flutter plugins, as well as VScode itself. I have also tried it on Android Studio.

I had the exact same issue using VSCode and found this which fixed the problem:



Run the following commands in the Flutter install directory:




  • git clean -xfd

  • git stash save --keep-index

  • git stash drop

  • git pull

  • flutter doctor
