What I mean is this:

Do I need to edit this line?:

      selectionHandleColor: Colors.grey,

If it that case, what parameters I have to write to convert the default blue color to a gray one?

  const test({Key? key}) : super(key: key);

  @override

}

  bool isHiddenPassword = true;

  @override

Wrap the textfield with a Theme widget. And in data add

ThemeData.light().copyWith(
  textSelectionHandleColor: Colors.green,
);

CodePudding user response：

ThemeData.dark().copyWith(
  accentColor: Colors.green,
  textSelectionColor: Colors.green.withOpacity(0.5),
  textSelectionHandleColor: Colors.green,
);
