CodePudding user response：

Your navigator code is wrong. You have to pass context before MateriaPageRoute too. Your Navigator must be like above :

 Navigator.push(
   context,
   MaterialPageRoute(builder: (context) => Body()));

CodePudding user response：

Change your following code:

Navigator.of(context).push( MaterialPageRoute(builder: (context) => Body()),);

Navigator.push(
    context,
    MaterialPageRoute(builder: (context) => const Body()),
  );

You need to pass a context and route to push method.

For more information about navigator, please go through the following link: https://docs.flutter.dev/cookbook/navigation/navigation-basics

@vaidarbhi: the form is correct in both cases...

@yassir outisket: Body should be a PAGE with scaffold or wont work.

Try next code for make a test with your function: Navigator.of(context).push( MaterialPageRoute(builder: (context) => TestPage(), ),);

import 'package:flutter/material.dart';

class TestPage extends StatefulWidget {

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

class _TestPageState extends State<TestPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Test'),
        ),
        body: Text("This is a test")
    );
  }
}
