    filled: true,
    focusedBorder: OutlineInputBorder(
      borderRadius: BorderRadius.circular(16),
      borderSide: const BorderSide(
        color: Colors.green,
        width: 2.0,
      ),
    ),
    enabledBorder: OutlineInputBorder(
      borderRadius: BorderRadius.circular(16),
      borderSide: BorderSide(
