使用不包含导航器的上下文请求导航器操作，即使第二条路由具有上下文

如何解决使用不包含导航器的上下文请求导航器操作，即使第二条路由具有上下文

 //main.dart file
 import 'package:Flutter/material.dart';
 import 'package:messenger/widgets/splash_screen.dart';

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

 class MyApp extends StatelessWidget {


 @override
 Widget build(BuildContext context) {
return MaterialApp(
  
  title: 'Flutter Demo',debugShowCheckedModeBanner: false,theme: ThemeData(
    scaffoldBackgroundColor: Colors.white,appBarTheme: AppBarTheme(
        brightness: Brightness.light,color: Colors.white,elevation: 0.0,iconTheme: IconThemeData(color: Colors.black),actionsIconTheme: IconThemeData(color: Colors.black)),fontFamily: "Ubuntu",primarySwatch: Colors.blue,primaryColor: Color(0xff0084FF),),home: Column(
  
    children: <Widget>[
      SizedBox(height: 30.0,ElevatedButton(
            onpressed: () => navigation(context),child: Text("to splash screen"))
      ],);
  }

 navigation(BuildContext context) {
   Navigator.of(context).push(MaterialPageRoute(builder: (context)=>SplashScreen()));
 }
  }


   //SplashScreen.dart file


   import 'package:Flutter/material.dart';
  import 'package:Flutter/widgets.dart';
  import 'package:messenger/widgets/login_button.dart';

   class SplashScreen extends StatefulWidget {
   @override
  _SplashScreenState createState() => _SplashScreenState();
 }

 class _SplashScreenState extends State<SplashScreen> {
  @override
   Widget build(BuildContext context) {
   double imageSize = MediaQuery.of(context).size.width / 3;
    return Scaffold(

      body: Center(
  
       child: Image.asset(
      "images/logo.png",width: imageSize,height: imageSize,fit: BoxFit.cover,bottomNavigationBar: Padding(
    padding: EdgeInsets.symmetric(
      horizontal: 16.0,vertical: 16.0,child: Column(
      mainAxisSize: MainAxisSize.min,children: <Widget>[
        LoginButton(text: "Continue with Facebook",onpressed: (){

        },colour: Color(0xff3b5998),leading: Image.asset("images/facebook-logo.png",],);
 }
  }

使用不包含导航器的上下文请求导航器操作。也许我没有很好地理解上下文的概念，这就是为什么我得到
错误。为什么会发生此错误？ SplashScreen 的第二个小部件具有语境。但我仍然收到错误。我的代码有什么问题吗错过了吗？

解决方法

兄弟，这不是在导航器中调用 Navigator.push 的好方法，请尝试在特定函数中调用，或者您可以在 ink well 中调用它，因此请删除 **Navigator(BuildContext context)** 之后它就可以为你工作了。

**这里是可以解决你导航问题的代码**

enter code here
  
import 'package:flutter/material.dart';

import 'screen/splashScreen.dart';

class DemoNavigation extends StatefulWidget {
  const DemoNavigation({Key? key}) : super(key: key);

   @override
    _DemoNavigationState createState() => _DemoNavigationState();
    }

  class _DemoNavigationState extends State<DemoNavigation> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),body: Container(
       child: Column(
          children: [
            Text("Navigator Demo"),ElevatedButton(
                  onPressed: () {
            // here is the function that your are using
                  navigation(context);
              },child: Text("TO Next Screen"),),],);
}

    /// here you need to change the context that your are passing to build 
     /// copy this   
    void navigation(BuildContext context) {
       Navigator.push(context,MaterialPageRoute(builder: (_) => 
      SplashScreen()));
   }
}
