CRASH (IOS): stream_chat_flutter conflict with video_editor

[4lb3rt0r]

Which packages are you using?

stream_chat_flutter
video_editor

On what platforms did you experience the issue?

iOS

What version are you using?

stream_chat_flutter: ^9.15.0
video_editor: ^3.0.0

What happened?

When adding the stream_chat_flutter dependency to my existing Flutter app (iOS target), the app crashes on startup.

After investigation, the crash is caused by a plugin conflict:

• stream_chat_flutter pulls in get_thumbnail_video, which registers VideoThumbnailPlugin.
• My project already depends on video_editor, which brings in video_thumbnail, and that plugin also exports a class named VideoThumbnailPlugin.

Both plugins expose the same Objective-C symbol name (FLTVideoThumbnailPlugin), which causes a duplicate symbol / runtime registration conflict on iOS.

When I remove either stream_chat_flutter or video_editor, the app runs fine. With both, it crashes immediately after launch.

Steps to reproduce

1. Create a Flutter project.
2. Add the following dependencies to `pubspec.yaml`:

   
   dependencies:
     flutter:
       sdk: flutter
     stream_chat_flutter: ^9.15.0
     video_editor: ^3.0.0
3. Run on iOS (simulator or device):
4. Observe the crash during startup.

Supporting info to reproduce

• Flutter SDK: 3.29.1

• Dart SDK: 3.7.0

• iOS Deployment Target: 15.5

• Device tested: iOS Simulator (iPhone 16 Pro, iOS 17)

• macOS: 15.6
  Direct deps in my project that are relevant:

• stream_chat_flutter: ^9.15.0

• video_editor: ^3.0.0 → depends on video_thumbnail

stream_chat_flutter transitive deps include:

• get_thumbnail_video: ^0.7.3

Logs thrown while trying to run the app on Xcode:

Relevant log output

VideoThumbnailPlugin is implemented in both
/Users/.../Frameworks/video_thumbnail.framework/video_thumbnail (0x11035d6d8) and
/Users/.../Frameworks/get_thumbnail_video.framework/get_thumbnail_video (0x110d55ee0).
One of the duplicates must be removed or renamed.
This may cause mysterious crashes.
