Mac M1 -- Error launching application on iPhone 12 Pro Max.(Flutter.h and AMSupportURLConnectionDelegate, AMSupportURLSession) issue

Question

I am new to ios development with flutter. While trying to build the app on ios simulator and external device (iphone xr), I get the following error--

objc[50354]: Class AMSupportURLConnectionDelegate is implemented in both ?? (0x1f3d2c188) and ?? (0x1184482b8). One of the two will be used. Which one is undefined.
    objc[50354]: Class AMSupportURLSession is implemented in both ?? (0x1f3d2c1d8) and ?? (0x118448308). One of the two will be used. Which one is undefined.
    ** BUILD FAILED **

Xcode's output:
↳

Could not build the application for the simulator.
Error launching application on iPhone 12 Pro Max.

Along with this, I am getting error in XCode AppDelegate.swift where it says-- "Flutter.h not found"

I am stuck on this issue for 2 weeks now and have tried almost all the solutions available to the problem.

Please help!

Using an M1 Apple Silicon chip, you may face those compiling errors about the Class AMSupportURLConnectionDelegate or AMSupportURLSession Class being implemented twice:

My trick to remove this issue is to use rosetta and recreate some files in your Flutter project.

Here's what to do:

Be sure you have a correct apple profile in your XCode Proj. (for code signing)
Be sure that you are opening terminal using Rosetta and not with ARM/Native

Then, and only then, try to run this command:

flutter clean && rm ios/Podfile ios/Podfile.lock pubspec.lock && rm -rf ios/Pods ios/Runner.xcworkspace && flutter run
