In flutter integration test, we generally enter the text by
await tester.enterText(find.byKey(ValueKey(key)), value);
But can anybody help me in clearing the entered text?
According to documentation:
Give the text input widget specified by finder the focus and replace its content with text...
https://api.flutter.dev/flutter/flutter_test/WidgetTester/enterText.html
you should be able to clear input text with:
await tester.enterText(find.byKey(ValueKey(key)), '');
