Found the solution!

Add the following to your pubspec.yaml

dependencies:
  # rest of your dependencies ...
  flutter_inappwebview: ^6.0.0 

# Add the following dependency overrides for iOS & macOS, as needed -->
dependency_overrides:
  flutter_inappwebview_ios:
    git:
      url: https://github.com/andychucs/flutter_inappwebview.git
      ref: master
      path: flutter_inappwebview_ios

  flutter_inappwebview_macos:
    git:
      url: https://github.com/andychucs/flutter_inappwebview.git
      ref: master
      path: flutter_inappwebview_macos

Nice find! Do you want to send a PR?

[Casuallynoted]

I’d love to! I’m away from home for the day but will try to get it submitted asap. If you don’t hear from me shoot me a reminder tomorrow and I’ll be home and able to put it in! :)

@Casuallynoted thanks for the report! I don't have access to a mac so ios development will be pr-driven for the foreseeable future. So if you're able to provide one, I'm more than happy to merge it!
