Looks like exists? was removed in ruby/ruby@bf97415 so the script won't work with very recent versions of Ruby.

/cc @jmagman

oh dear

Looks like it was removed in Ruby 3.2, which is still in preview. Ruby 3.1.2 was the last released version.

What's the output of $ ruby -v
If you open path/to/flutter-sdk/packages/flutter_tools/bin/podhelper.rb and change this line:

- return [] unless File.exists? file_path
+ return [] unless File.exists file_path

does the flutter command succeed on your iOS project?

Error resolved by switching to Ruby3.1.2

Error resolved by switching to Ruby3.1.2

Can you switch back and validate that the diff works on 3.2?

@jack7758258

@jack7758258 alternatively, the fix #109428 has merged into master. Can you switch back to Ruby 3.2 preview, check out the Flutter master channel and validate that you are able to build your iOS app? Your validation of the fix would be really helpful!
