Integrate a Flutter app in to another Flutter app

Question

I have a bigger app named X and I have another smaller one named Y. they are right now separate from each other and they are working fine. I want to integrate app Y in X. I want to put codes of Y in X project but they should have a different Main so I can set different themes and routes. Is there any way to do that?

Update

I am using GetMaterialApp from GetX instead of MaterialApp, and it returns error:

'package:flutter/src/widgets/framework.dart': Failed assertion: line 5334 pos 14: '_dependents.isEmpty': is not true.

How can I fix this?

You can use multiple MaterialApp() in your project, combine the code/file like that the app is on another screen, and you will result in apps that have different references to their InheritedWidgets like Theme, Navigator, MediaQuery...

 /*...*/
 MaterialApp(
 /*...*/
   home: AppXHome(),
  ),
 /*...*/

class AppXHome extends StatelessWidegt {  
 @override
 Widget build(BuildContext context) {
  return Column(
   children: <Widget>[
   Container(),
   Container(),
   MaterialApp(
   home: AppYHome(),
     ),
    ],
   ),}}
