Flutter Braintree not working in Apple M1 - flutter

Question

I am having issues while compiling Flutter Braintree in Apple M1.
I even tried creating a new project only with flutter_braintree 2.2.0, still doesn't compile.
Attached is the flutter doctor and logs of the project.

Answer 1

Add this code on the Podfile,
post_install do |installer|
installer.pods_project.build_configurations.each do |config|
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end
And from Xcode pass to build iOS 9.0 to 12.0
