Why the test folder automatically gets created on flutter projects, inside this folder the file widg-CodePudding

It comes all of my Flutter Projects. Is the folder necessary or not ? Do I delete the folder ?

CodePudding user response：

Basically runApp() method(inside main.dart) contains a class and it should be same as defined in this tester.pumpWidget(....) method. If they don't match, it causes this error.

e.g In your main.dart if runApp() method is having a class HomePage runApp(const HomePage()); then inside widget_test.dart file it should be like await tester.pumpWidget(const HomePage());

CodePudding user response：

Remove const. like await tester.pumpWidget(MyApp());
