Flutter app not running on iOS Simulator running on m2 processor

My Flutter app runs perfectly on M1 processor. Now, I have upgraded to the new M2 processor. After installing everything when I run the app on my iOS Simulator, I get the following error:

Launching lib/main.dart on iPhone 14 Pro in debug mode...
Running Xcode build...
Xcode build done.                                           22.0s

Error launching application on iPhone 14 Pro.

I tried cleaning flutter project. Cleaning build folder from xcode. Removing pods file, PodFile.lock. Nothing seemed to work. Any help will be greatly appreciated.

    Have you double checked to make sure your build configuration is set to debug and not release? I hand’t noticed mine changed to release after switching laptops

    You have to put arm64 for simulator
    OR
    You can set arm64 in pods.

    post_install do |installer|
      installer.pods_project.build_configurations.each do |config|
        config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"

    enter image description here
    end
    end
