class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Theme(
      data: ThemeData(primaryColor: Colors.purple),
      child: TextField(
        decoration: InputDecoration(
          labelText: "Password",
          fillColor: Colors.white,
          border: OutlineInputBorder(
            borderRadius: BorderRadius.circular(30.0),
            borderSide: BorderSide(
              color: Colors.purple,
            ),
          ),
          enabledBorder: OutlineInputBorder(
            borderRadius: BorderRadius.circular(30.0),
            borderSide: BorderSide(
              color: Colors.purple,
              width: 2.0,
            ),
          ),
        ),
      ),
    );
  }
}
