String _result = 'Unknown';
final _phoneNumberHintPlugin = PhoneNumberHint();
TextEditingController _controller = TextEditingController();

@override
void initState() {
super.initState();
}

// Platform messages are asynchronous, so we initialize in an async method.
Future<void> getPhoneNumber() async {
String? result;
// Platform messages may fail, so we use a try/catch PlatformException.
// We also handle the message potentially returning null.
try {
result = await _phoneNumberHintPlugin.requestHint(
) ??
'';
_controller.text = result;
} on PlatformException {
result = 'Failed to get hint.';
}

// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;

setState(() {
_result = result ?? '';
