        // check that it really is our d

when I tab on a textview inside my app.

This is how i initialize the app itself.

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ScreenUtilInit(
      designSize: Size(460,790),
      builder: (context) => MultiProvider(
          providers: [
            ChangeNotifierProvider(create: (context) => TestApp()),
            ChangeNotifierProvider(create: (context) => PageControllerProvider()),
            ChangeNotifierProvider(create: (context) => RequestProvider()),
            ChangeNotifierProvider(create: (context) => HistoryProvider()),
            ChangeNotifierProvider(create: (context) => ThemeProvider()),
          ],
          child: App()
      ),
    );
  }
}

Answer 1

try updating flutter_screenutil to version 5.5.2 or higher

Answer 2

If you are using the current version of Flutter (v2.10.2>=),

ScreenUtil package creates a conflict with that version.

If you downgrade your Flutter version back to v.2.10.2, the error will be fixed.
