module 'audio_session' not found

Question

I try to build an existing flutter project on a new Mac with M1 chip. I face the following error in regards that the audio_session module is missing.

Any thoughts?

make sure you have added `audio_session` package in `pubspec.yml` file. after then run the command `flutter pub get` and `flutter run` — Ranjit Shrestha, Mar 18 '21 at 13:38
I don't use this package at all. I think somehow it is a dependency. — Alexandru Rusu, Mar 18 '21 at 13:57
I cleaned the pod file and I figure out that 'flutter run' generated a more complex Podfile. Anyway, another error is generated Error: To set up CocoaPods for ARM macOS, run: arch -x86_64 sudo gem install ffi Even if I run the command that was mentioned, the same error occur. — Alexandru Rusu, Mar 18 '21 at 13:59
Running into the same problem. I'm using [just_audio](https://pub.dev/packages/just_audio/versions) which depends on `audio_session`. — kohjakob, Mar 18 '21 at 15:50
Okay, I think my problem was opening `ios/Runner.xcodeproj ` instead of `ios/Runner.xcworkspace`. More on that [here](https://stackoverflow.com/a/63970985/13793197) — kohjakob, Mar 18 '21 at 15:56

You should

1 . open "Runner.xcworkspace" in xcode , Not "Runner.xcodeproj"

2 . everything going well

In my case I used the terminal to build, by running `flutter run`. I already posted an answer down below. – Alexandru Rusu May 16 '21 at 06:49
okay , i got same question other day , and cause i open "Runner.xcworkspace" in xcode – capdev May 16 '21 at 12:42
Any solution to this?? I opened Runner.xcworkspace...but still get this issue – Sandz Mar 09 '22 at 09:24

Finally, found a solution.

Somehow, If I went to the iOS folder of my flutter project and type 'pod init; pod install' a basic Podfile was generated (meaning that it had specified only the platform).

I found a post somewhere that suggested to delete everything in the iOS folder about pod and to run flutter run in the project. Running 'flutter run' in the project folder (that integrates 'pod install' as well), generated a much detailed Podfile, but this time I faced another error in regards with the platform (listed below).

Error output from CocoaPods:
↳

    [!] Automatically assigning platform `iOS` with version `12.0` on target
    `Runner` because no platform was specified. Please specify a platform for
    this target in your Podfile. See
    `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error: To set up CocoaPods for ARM macOS, run:
  arch -x86_64 sudo gem install ffi

I tried to follow the suggestion to run the command shown above, but the same error occurred.

Then, I found an answer here Running Cocoapods on Apple Silicon (M1) that is similar with the official documentation https://github.com/flutter/flutter/wiki/Developing-with-Flutter-on-Apple-Silicon.

Even so, the answer from the stack overflow didn't work straight forward for me until I followed these steps:

Open finder -> Utilities
Right click on the Terminal -> Get Info
Check 'Open with Rosetta'
Open a new terminal and type 'gem uninstall cocoapods'
sudo gem install cocoapods
gem uninstall ffi
arch -x86_64 sudo gem install ffi

I hope this is useful for someone else.

should we install cocoapods back? – temirbek May 12 '23 at 06:26 — temirbek, May 12 '23 at 06:26

For me, it build succesfully after I ran flutter clean.

flutter clean
flutter pub get
flutter build ios

It worked for me.

In my case, I had changed the platform :ios to '13.0', but my iOS Deployment Target was '9.0'. I left the two the same and it started working again.

Make sure platform: iOS version in pod file matches with deployment info in Xcode
