This is the error I am receiving.
I tried flutter clean and changing the syntax of some lines, but I’m new to Dart and Flutter, so im not really sure. I reinstalled CocoaPods and the Ruby interpreter as well, but I’m receiving the same error. I also made sure to update the Ruby interpreter to the latest version.
