I need a TextField for entering a password in uppercase.
I thought it would be easily done like this:

void main(List<String> args) {
  runApp(MaterialApp(
    home: Scaffold(
      body: Center(
        child: TextField(
          textCapitalization: TextCapitalization.characters,
          obscureText: true,
        ),
      ),
    ),
  ));
}

But it doesn’t work: it seems like TextCapitalization.characters and obscureText are incompatible, the keyboard is in lowercase… Any idea?
