iOS ImageNotification extension missing DEVELOPMENT_TEAM causes App Store deployment failure

[rorymackay2688-wq]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

When deploying the iOS app from FlutterFlow, the generated ImageNotification extension target uses automatic signing but does not receive a DEVELOPMENT_TEAM value for Debug, Release, or Profile.
The main Runner target signs correctly, but the extension fails with:
Signing for "ImageNotification" requires a development team.
The generated extension bundle ID is com.mycompany.toolio.ImageNotification. Manually editing the generated Xcode project would only be temporary because FlutterFlow regenerates project.pbxproj on deployment.

Expected Behavior

FlutterFlow should assign the same Apple Development Team used by the Runner target to the generated ImageNotification extension target for all build configurations.
For this project, the Team ID is TWA3YQZ4Q9.
The generated extension should therefore include DEVELOPMENT_TEAM = TWA3YQZ4Q9 for Debug, Release, and Profile so the app can be signed and deployed to the App Store through FlutterFlow without manual Xcode changes.

Steps to Reproduce

1. Open the Toolio project in FlutterFlow.
2. Ensure iOS deployment is configured with the Apple Developer Team and valid App Store Connect credentials.
3. Keep Push Notifications enabled so FlutterFlow generates the ImageNotification extension target.
4. Deploy/build the iOS app through FlutterFlow.
5. Observe that the main Runner target signs correctly.
6. The build then fails on the generated ImageNotification target with:
   Signing for "ImageNotification" requires a development team.
7. Inspect the generated Xcode project and confirm that ImageNotification has CODE_SIGN_STYLE = Automatic but no DEVELOPMENT_TEAM value for Debug, Release, or Profile.
   The issue reproduces on this project without any manual Xcode changes.

Visual documentation

The attached build output shows the iOS deployment failing because the generated ImageNotification extension target does not have a Development Team assigned.
Error:
Signing for "ImageNotification" requires a development team.
The main Runner target is configured correctly. The issue is isolated to the FlutterFlow-generated ImageNotification extension.

Hello!

This appears to be a configuration issue in App Store Connect rather than a FlutterFlow issue.
