TextScaleFactor for TextField in Flutter?

Issue

Was wondering is there a way to control textscalefactor for TextField widget in flutter. Basically I want to limit a text field from growing too large when a user increase font/text size in their devices accessibility settings.

Thanks.

Solution

You can wrap it with a MediaQuery with a custom textScaleFactor

Widget build(BuildContext context) {
  final mqData = MediaQuery.of(context);
  final mqDataNew = mqData.copyWith(textScaleFactor: mqData.textScaleFactor > 5.0 ? 5.0 : mqData.textScaleFactor)
  return MediaQuery(data: mqDataNew, child: TextField());
}

The TextField does not need to be a direct child of MediaQuery.
