Flutter application crashes on iOS devices due to audio_players darwin plugin

Question

I am currently facing an issue regarding my Flutter application. It is currently working fine on Android and all the relative devices but I have a problem with iOS simulators.

The log that I am getting is the following:

It seems like the problem is related to the audioplayers_darwin plugin not being able to startup and crashing the application on launch, without even opening it.

I am not sure if has something to do with Xcode and Flutter versioning or with some plugins' dependencies but I'll leave here some screenshots of the things that I checked.

pubspec.yaml Pods

I tried many and different solutions found on online:

• Cleaning the project and building it again
• Cleaning the pods and re-create them again
• Update Flutter and the dependencies
• Even deleting the whole ios folder and creating it again audioplayers_darwin plugin List of ios plugins

Answer 1

After many days, I found the problem, you need to build in "release" mode instead of "debug" mode. It's not related to the audio_players darwin plugin. You will have the same problems for others publings.
