How to handle back button on appBar of Scaffold layout in flutter module and navigate to previous page on the host app

I have a question, I have to create a flutter module and integrate it directly into the host app. I want to handle the back button on flutter UI by clicking it and navigating to the previous page on the host app. I use go_router to handle navigation on the module and host app. I have never integrated it. I have no idea to handle the back button it works on the appBar inside the flutter module. In this case, I would like to handle it by method channel or not?

I just found a way. After setup the flutter module inside Android or iOS, We can use this code setup inside the AppBar to close the page.
if(Platform.isAndroid){
SystemNavigator.pop();
} else {
exit(0);
}

Single page navigation with flutter web

I'm trying to create a web app that only renders one page, and the other pages (or views) are rendered when you press a button related to that specific view. Like the Flutter Gallery website, when you click on a widget info in the "Categories" section
Is there any workaround for this or do I have to create my own router?
you can keep all widgets on one page package by creating a switch statement in your build page. switch between different widget when rendering the scaffolding.

Can I store a widget from widget and later use it in another page without rebuilding it from scratch? - Flutter

I have a Stateful widget called Widget1 shown in one page. When I open my app the widget1 gets build from scratch and shown in the page. Let's assume the widget1 is quite heavy with lot's of other widget's inside it.
Now I want to display the same widget in another page but I don't want to build the same widget1 from scratch like I did in the first page. I want to reuse the widget which was built in the Previous page to be shown in this page.
Is that possible in flutter? I know flutter must build a widget inorder to make changes in Ui. But is this really possible? that is , to store a widget and use it, whenever we want without having to rebuild it, again from scratch?.
