Flutter - Develop 'A Multiple Screens View' (Like 'Chrome Tabs')

Hi =). How are you? =). I hope you are all doing well =). I am needing someone to 'give me the code' of how to develop, let's say, A Screen in which I could view 'multiple different versions of the same screen opened' (like 'The Multiple Tabs View' in The Chrome Mobile App). Just that 'instead of capturing a screenshot of each screen, when left, to display it later in the multiple tabs view', I would need, only if possible, 'a live view of each screen displayed in the 'Multi Screens' Screen'. And, by the way, 'The Example App has to only include 3 different example screens', 'but opened, like, let's say, 5 or 6 times each screen, with different data inside'. So I would have 3 types of screens, for example: A) Countries Screen. B) Football Teams Screen. C) Animals Screen. And I would need, A Fourth Screen in which I could see, for example. Two Screens Open of Type A (with 'United States' written in one of the two, and 'India' written in the other). Two Screens Open of Type B ('Milan FC' written in one of the two, and 'Bayern Munich' written in the other). And Two Screens Open of Type C ('Cats' written in one of the two, and 'dogs' written in the other one). So, I need 'Three Base Screens', 'opened X Times Each Type of Screen', with a Fourth Screen that would consist on 'The Live View of The Total of Screens Opened' (which could be 5, or 10, or 20 screens opened, like in The Chrome Tabs of Such Mobile App). If you understand what I need, and can do it, do not doubt to send me a message. Thank you. Be seeing you. Damian.
