Flutter Ambient UI - What should be the optimised approach for production level responsive app in web, android and ios platform using single codebase?

I was trying out flutter platform to create a multipage website with android and ios responsiveness using single codebase for my flutter app. I've already tried some single page samples in flutter which are following,
Flutter web, android & ios using Stacked architecture & Responsive_builder
Flutter web, android & ios using MVVM & Responsive_Framework
Flutter web, android & ios using simple Getx package.
All of them are working fine, but what I want is to collect your opinions who have already created a production ready app in flutter web.
Should we consider using Navigator 2.0 for flutter web responsiveness?
Does responsive_framework package work fine if we have complex designs because I'm not confident about the font size and styling application using it?
Can we use any other app architecture, responsive package, design pattern or any other concepts for multipage production level use cases.
Any suggestions would be appreciated.
Thanks.

How can I make the application run in the background on flutter?

I am creating a lock screen application on flutter for ios and android, I want the application to work in the background, i.e. when the phone screen is turned on, the window for entering the pin code of my application "pops out", how can this be done?
Well, there is no direct solution on flutter yet. For sure there is no solution for ios. You will have to write both java/kotlin and swift/objective c and use the invoke methods to call your native functions.
native is a word we use for the specific platform code. for example native android means java or kotlin and swift or objective c for ios.

How to do keypress like Java Robot in Flutter Desktop?

I am stuck with my flutter desktop application development. I'm looking for features like Java Robot for send keypress from my Flutter desktop application. Unfortunately, I did not find any Flutter desktop plugin or core functionality in Flutter.
Robot r = new Robot();
r.keyPress(KeyEvent.VK_E);
r.keyRelease(KeyEvent.VK_E);
Flutter does not have any APIs for posting synthetic events to the OS. You would need to write native code (either as a plugin, or directly in the native part of your application) for each platform to do that.

How can we implement snapchat like filters in flutter using ArCore

I am trying to build an augmented reality application using flutter and i came to know that there are two libraries available for flutter
arcore_flutter_plugin for Android and arkit_flutter_plugin for IOS can anybody suggest me how can i implement snapchat like camera filters and record that video.
I don't think this is the correct approach to get a working face-filter project.
As far as I know - I am working on a similar project - the best choice as of now is DeepAR, which may enable you to work with some sort of Snapchat like face-filter.

Flutter UI Components plugin or module

i have experience android and IOS and react native also . the best thing that i love react native is allow to create ui native component to bridge to react native .
is it possible create ui in Kotlin/Java and Swift/Objective-C and bridge to flutter?
No that's not possible, or at least shouldn't be done.
Flutter's approach on UI rendering is the opposite of React-Native. React-Native is a binding to OS native components. While Flutter recreated the Material/Cupertino components from scratch.
If you really insist on doing it consider diving into the code of video_player
or map_view plugin. But they are unique
