Flutter ShareExtension for iOS: Flutter code executes however does not render UI

Flutter iOS Share Extension UI Not Rendering

I’m attempting to create a Share Extension in Flutter for iOS, following the official Flutter information: Creating App Extension UIs with Flutter.

Drawback

Whereas each Swift and Dart code seem to execute efficiently (as confirmed by logs), the Flutter UI doesn’t render. As a substitute, solely the background view (inexperienced) is displayed, and the Flutter app content material by no means exhibits up.

Right here’s a minimal instance repository I’ve created to breed the problem:

Observations

1. GIF demonstration:
   The inexperienced background view is displayed, however the Flutter content material is lacking. https://ibb.co/cbMTySH

2. Xcode logs:
   Logs verify that Dart and Swift code are executed as anticipated. https://ibb.co/Wkz1Nw2

Extra Info

Any insights into why the Flutter UI isn’t rendering or learn how to resolve this might be tremendously appreciated! Thanks! 😊

• Debugged a number of occasions to hint the problem, however the root reason behind the lacking Flutter UI stays unclear.
• Tried with totally different Flutter variations (3.27.1, 3.24.0, and 3.22.0) to rule out version-related issues. The difficulty persists throughout all examined variations.
