I tried your reproduction steps but it worked fine for me. Can you please upgrade to the latest Flutter SDK and Xcode?

[ryanheise]

Can you confirm these reproduction steps? Does it really happen if creating a new flutter project? i.e.:

1. Click to 'New Flutter Project" in Android Studio and create a new app

In the off chance that that's not the case, can you try cleaning your build files from Xcode?

[tcerven]

I upgraded to the latest Flutter and xcode. I tried cleaning the build files. Same problem. I did have a similar problem with different plugin that used pods but now that one works after the flutter upgrade:

flutter --version Flutter 1.23.0-18.1.pre • channel beta • https://github.com/flutter/flutter.git Framework • revision 198df796aa (3 weeks ago) • 2020-10-15 12:04:33 -0700 Engine • revision 1d12d82d9c Tools • Dart 2.11.0 (build 2.11.0-213.1.beta)
Still, it's possible my flutter SDK is still messed. Is that the latest version?

Or my podfile is messed up. See attached Podfile.txt. Here is the error from xcode:

Showing Recent Messages /Users/tomc/projects/flutter_autdio_stake/ios/Flutter/Debug.xcconfig:1: could not find included file 'Pods/Target Support Files/Pods-Runner/Pods-Runner.debug.xcconfig' in search paths
It's duplicated 4 times.

I can confirm that it doesn't happen with the standard "New Flutter Project" project. That works just fine.

Did you clean through the Xcode menu or did you do flutter clean?

I can confirm that it doesn't happen with the standard "New Flutter Project" project. That works just fine.

Can you update your bug report with a valid minimal reproduction project?

[timilehinjegede]

I have this same issue!

[timilehinjegede]

I fixed it after following the steps below:

1. Deleted the ios directory
2. Runflutter create .
3. Change to the ios directory (cd ios).
4. Run pod deintegrate
5. Run pod install

[ryanheise]

@tcerven can you confirm this?

First, in terms of cleaning the iOS build files from the Xcode menu (or running pod deintegrate/install), did that alone fix the error? Did it overcome the error but reveal a second error? If you still had an error, did flutter create . resolve it?

[timilehinjegede]

If after trying the above solution and the error still persists. This is because you don't have a valid podspec file in the just_audio_web directory.

1. Go to the ios directory of your Flutter project.
2. Find .symlinks > plugins > just_audio_web > ios
3. Rename the generated podspec file to just_audio_web.podspec

I have sent a PR to fix this.

[ryanheise]

Thanks, @timilehinjegede I've merged your PR. Note that the existing file wasn't auto-generated, I had copied it from the url_launcher plugin which served as a template for creating a federated plugin, and did various substitutions to use the just_audio package name (but forgot the file name!). It's a weird quirk that a web plugin needs an ios directory with a podspec, although from memory that will be fixed in a future version of Flutter.

[timilehinjegede]

Thanks for the clarification @ryanheise!
