Flutterfire: 🐛 [firebase_messaging] Notification Images setup problem iOS

[aytunch]

Bug report

Describe the bug

In iOS, When trying to setup FCM(with image support) the app does not compile. The documentation steps result in errors.

Steps to reproduce

Steps to reproduce the behavior:

1. Create a clean Flutter app and add FCM setup for iOS.
2. Go to (Advanced, Optional) Allowing Notification Images and do the necessary steps.
3. For the step named "Add target to the Podfile", copy paste the exact:

target 'ImageNotification' do
  pod 'Firebase/Messaging'
end

1. Do the next 2 steps as written in the flutter fire docs
2. Since there is no use_framewroks! in the docs, we get this error:

[!] Unable to integrate the following embedded targets with their respective host targets (a host target is a "parent" target which embeds a "child" target like a framework or extension):

- Runner (true) and ImageNotification (false) do not both set use_frameworks!.

1. If i add the use_frameworks!, then it compiles, but I get this error:

ld: '/Users/berat/Documents/projects/sponty_missions/video_tutorial/build/ios/Debug-iphoneos/PromisesObjC-iOS14.2/FBLPromises.framework/FBLPromises' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/berat/Documents/projects/sponty_missions/video_tutorial/build/ios/Debug-iphoneos/PromisesObjC-iOS14.2/FBLPromises.framework/FBLPromises' for architecture arm64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

Expected behavior

FCM has Image capabilities as expected and the project compiles without error

---

Additional context

I tried both creating the Image Notification Service Extension as an Objective C file and a Swift file. Nothing changed
Also I tried enabling the bitcode setting but still no luck.

Compiling works when adding this and setting bitcode to no for the ImageNotification target:

target 'ImageNotification' do
  use_frameworks!

  pod 'Firebase/Messaging'
end

[aytunch]

@DFelten compiling works when use_frameworks is added however it crashes once it compiles.

[VictorUvarov]

Compiling works when adding this and setting bitcode to no for the ImageNotification target:

target 'ImageNotification' do
  use_frameworks!

  pod 'Firebase/Messaging'
end

Disabling bit_code and use_frameworks! did the trick! Thanks. Is this only needed for projects that have swift support?
