Hi @xioxin . Thanks for resolving my previous flutter pub get issue.

I am having another difficulty so I opened this dedicated issue here. Currently, I am trying the example project on the iOS simulator. However, all the example pages of the app give this error:

Unhandled Exception: Invalid argument(s): Failed to lookup symbol 'InitDartApiDL': 
dlsym(RTLD_DEFAULT, InitDartApiDL): symbol not found

This might help you figure it out:

Searched the net for Failed to lookup symbol and I have encountered something like that:

This is might be a similar problem. I changed the Strip Style as told. However, I couldn't find a solution.

Sorry this was a mistake on my part. I checked and found that the macOS & iOS binaries were not properly committed to git.

To ensure that flutter pub get can be updated correctly, you can specify ref

  lab_sound_flutter:
    git:
      url: https://github.com/xioxin/lab_sound_flutter.git
      ref: 656b23d

You can also check pubspec.lock to make sure the version is correct
