在flutter项目的入口文件main.dart中编辑如下

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],
      supportedLocales: [const Locale('zh', 'CN'),const Locale('en', 'US'),],
      title: 'xxx',
      theme: myTheme(),
      // 以下是关键
      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: Home({}),
    );
  }
