Flutter Focus Widget #

一个可以让FocusNode失去焦点的Widget #

A focusable and blurable widget of use the FocusNode. #

• 当FocusWidget获得焦点后

  在FocusWidget域外触发PointerDown

  会让FocusWidget失去焦点

  并且触发FocusNode的listener

• When the FocusWidget has focus

  Trigger the PointerDown event outside the FocusWidget area

  Will make FocusWidget lose focus

  And trigger the FocusNode listener

class _MyHomePageState extends State<MyHomePage> {
  final FocusNode _address = FocusNode(), _name = FocusNode();

  @override
  Widget build(BuildContext context) {
    final language = DemoLocalizations.of(context);
    return Scaffold(

              FocusWidget.builder(
                context,
                (ctx, focusNode) => TextField(
