Flutter：EasyLoading库找不到MediaQuery小部件错误

Question

我使用EasyLoading库（https://pub.dev/packages/flutter_easyloading）。一切正常。但是当我双击 TextFormField 时，会发生此错误。 我试图将MaterialApp设置为根窗口小部件，并将EasyLoading设置为子级，但这一次EasyLoading无法正常工作。 我的代码：

 void main() {
      runApp(MyApp());
      configLoading();
    }

    class MyApp extends StatelessWidget {
      @override
      Widget build(BuildContext context) {    
        return FlutterEasyLoading(
            child: GestureDetector(
          onTap: () {
            FocusScopeNode currentFocus = FocusScope.of(context);
            if (!currentFocus.hasPrimaryFocus) {
              currentFocus.unfocus();
            }
          },
          child: MaterialApp(
            home: StartPage(),
            debugShowCheckedModeBanner: false,
          ),
        ));
      }
    }
