Solution 1

1. Install Rosetta 2 on Your Mac M1 by executing this in terminal:

softwareupdate --install-rosetta

2. Select the app(terminal) in the Finder.
3. Right click on the app(terminal) and select Get Info.
4. In General, check the Open using Rosetta check-box.
5. Close the terminal Info.
6. Quit terminal and open it again.
7. Now in terminal write the following in front of your command:

arch -x86_64 [your command]

Solution 2

I have same issue and resolved by accident. Give it a try (not sure if this works)

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

Solution 3

I solved this issue yesterday;

Please check out your apple dev account on your xcode first, and run your project using xcode, and input your password, trust your certificate. After your xcode build success, you can run it on your idea （Android Studio） now.

did you found a solution to fix this problem? @Prasath

[Prasath]

as i searched in the internet, this is related to xcode developer sign in , check the certificate, stackoverflow.com/a/67159933/5359340

[daniel.gindi]

M1 is a very good product for the developer. And the developer should have enough knowledge to understand that M1 is a first generation which means not all software has adjusted yet, and enough to run rosetta with arch -x86_64 .... whatever command you want

@daniel.gindi this is the worst case of developer gas lighting i think ive ever seen

[daniel.gindi]

@martinseal1987 I do not know how to interpret your comment, but have you seen the original wording? I've never seen an "answer" so subjective and useless on SO in my life.
