The 'Pods-Runner' target has transitive dependencies

[aloisdeniel]

Steps to Reproduce

Install my appcenter plugin and add initialisation code in your app :

  @override
  initState() {
    super.initState();
    initPlatformState();
  }

  Future initPlatformState() async {
    await AppCenter.start("<_app_secret>");
  }

The code works well with the local example generated with the plugin project template, but when installing with the dart package its doesn't work : I get the following error.

The 'Pods-Runner' target has transitive dependencies that include static binaries:  ...

I first saw that in the local example project, the Podfile doesn't have the use_frameworks! command, so I removed it. But it fails too and the library doesn't seem to be present.

Okay, after further investigation I now know why the sample project works, and not my actual project that depends on it through Pub.

When generating a plugin template, the generated example Runner project was based on Objective-C :

However the project I then created from Intellij is based on Swift :

So the use_frameworks! directive makes senses in my Swift project, but why doesn't it achieve to reference the various transitive pods ?

[aloisdeniel]

I also compared the AppCenter plugin to the Firebase plugin that are both implemented in Objective-C, with a dependency to a pod implemented in Objective-C.

The only potential difference I see in Firebase/Core podspec, compared to AppCenter podspec that could be a problem is the s.static_framework = true directive.

cc @mravn-google and @collinjackson who might have more insights.

@aloisdeniel We do seem to need s.static_framework = true in podspecs when Swift is involved in the app and using CocoaPods 1.5.0 or later.

FYI - I ran into this issue just yesterday when running my app on iOS for the first time in a while after having added in the google_map_flutter plugin. It turns out the fix was to replace my ios/Podfile with a newer one (I pulled the one from the google maps example). I believe mine was generated a few months ago when I started this project--I can't remember. In comparing it to the google maps flutter example Podfile there were quite a few differences and so it was easiest to just replace it.

From this commit (flutter/plugins@20f9e7a ) I see that there is some work to clean up Podfiles in the plugins repo to make sure the latest is always used.

Ran into this problem, versioned down to cocoapods 1.4.0 and it resolved. Of course I'm running into another pod issue right now, but it's unrelated to this...

[RaduGrama]

@mravn-google, can you comment on your earlier statement "We do seem to need s.static_framework = true in podspecs when Swift is involved in the app and using CocoaPods 1.5.0 or later." please. Is that a "do need", "do not need", "maybe need"? This issue is still open...

[mravn-google]

@RaduGrama As far as I know, we do need that declaration, see

https://blog.cocoapods.org/CocoaPods-1.4.0/#static-frameworks

It is used 14 times in the flutter/plugins repo to deal with transitive dependencies on static binaries.

For me, I deleted the ios/Flutter/Flutter.framework folder and install pods pod install again then it worked.

It works...

Worked for me too!

I dont quite understand whats the override for this to work, I'm not able to use 1.4.0 version of Cocoapods, my project requires at least 1.10.0

I thought this would be fixed by #70224, but users in duplicate #20045 claim it didn't.
