TextField maxLength property is not working correctly. #67236
Description
Sample app:
void main() => runApp(App());
class App extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: TextField(
maxLength: 5,
maxLengthEnforced: true
)
)
)
);
}
}
When I enter only letters into the TextField, the length is not restricted and I can enter an unlimited amount of characters. When I enter only numbers into the TextField, it does not display more than 5 characters (as it should) although pressing backspace is bugged when typing more than 5 numbers. Example: If you type 12345678, the TextField will show 12345 but typing backspace will do nothing 3 times as if the TextField contains 12345678 but is only showing 12345.
