Flutter 效果实现 —— 全局点击空白处隐藏键盘

全局设置点击空白处隐藏键盘：

class App extends StatelessWidget {
  App({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'DismissKeyboard Example',
      builder: (context, child) => Scaffold(
        body: GestureDetector(
          onTap: () {
            FocusScopeNode currentFocus = FocusScope.of(context);
            if (!currentFocus.hasPrimaryFocus &&
                currentFocus.focusedChild != null) {
              FocusManager.instance.primaryFocus?.unfocus();
            }
          },
          child: child,
        ),
      ),
      home: DismissKeyboardPage(),
    );
  }
}
