flutter报错Navigator operation requested with a context that does not include a Navigator

此问题一般情况出现在直接在main.dart文件中操作路由。

如上情况提示路由控制器需要一个context但是当前navigator并不包含，通俗的讲要使用路由(Navigator)，根控件不能直接是 MaterialApp.

解决方法：将 MaterialApp 内容再使用 StatelessWeight 或 StatefulWeight 包裹一层

void main() async{await setupServiceLocator();/// 微信、QQ注册runApp(MultiProvider(// 状态管理providers: [ChangeNotifierProvider(create: (_) => UserProvider()),],child: MyAppPrepare(),//解决MaterialApp中的跳转路由的context问题));
}///解决MaterialApp中的跳转路由的context问题
class MyAppPrepare extends StatelessWidget {@overrideWidget build(BuildContext context) {return MaterialApp(debugShowCheckedModeBanner: false,builder: (context, widget) {return MediaQuery(///设置文字大小不随系统设置改变data: MediaQuery.of(context).copyWith(textScaleFactor: 1.0),child: FlutterEasyLoading(child: widget),);},home: GestureDetector(/// 全局键盘关闭onTap: () {FocusScopeNode focusScopeNode = FocusScope.of(context);if (!focusScopeNode.hasPrimaryFocus &&focusScopeNode.focusedChild != null) {FocusManager.instance.primaryFocus?.unfocus();}},child: MyApp(),),theme: ThemeData(primarySwatch: ColorTool.white),localizationsDelegates: [RefreshLocalizations.delegate,GlobalMaterialLocalizations.delegate,GlobalWidgetsLocalizations.delegate,CupertinoLocalizationsDelegate(),],supportedLocales: [Locale('zh', 'CN')],);}
}class MyApp extends StatefulWidget {@overrideState<StatefulWidget> createState() {return _MyAppState();}static BuildContext getContext() {return _MyAppState.getContext();}
}class _MyAppState extends State<MyApp> with WidgetsBindingObserver{RouteManager _routeDelegate = RouteManager();
static BuildContext appContext;static BuildContext getContext() {return appContext;}@overridevoid initState() {super.initState();//添加观察者，检测页面生命周期WidgetsBinding.instance.addObserver(this);EventBusUtils _event = EventBusUtils.instance;if (CacheManager.shared.prefs != null && CacheManager.shared.getString("isShowAgreement") != null) {_prepareInitIM();}}@overridevoid dispose() {super.dispose();//页面销毁时，移出页面生命周期监听者WidgetsBinding.instance?.removeObserver(this);}@overrideWidget build(BuildContext context) {appContext = context;return FutureBuilder<CacheManager>(future: CacheManager.preInit(context),//进行初始化builder: (BuildContext context, AsyncSnapshot<CacheManager> snapshot) {//定义routevar _widget = (snapshot.connectionState == ConnectionState.done && snapshot.data != null)? Router(routerDelegate: _routeDelegate): snapshot.connectionState != ConnectionState.done? Scaffold(body: Center(child: CircularProgressIndicator(color: ColorTool.red),),):_showAgreementWindow(appContext);return _widget;},);}
