Unable to add my app with Transporter. Some type of model mismatch?

I am having a difficulty with my Flutter app, it builds okay however when shifting it to Transporter to get it on App Retailer Join I get a message:

Validation failed (409)
Invalid Bundle. The bundle Runner.app/Frameworks/App.framework doesn't help the minimal OS Model specified within the Data.plist. (ID: 44df568a-1707-444a-b31e-d69f9c2b8749)

I do not know what’s inflicting it. I’m concentrating on a minimal iOS model 15 due to my dependencies.

These are:

  url_launcher: ^6.3.0
  path_provider: ^2.1.5
  flutter_email_sender: ^7.0.0
  email_validator: ^3.0.0
  open_filex: ^4.7.0
  plugin_platform_interface: ^2.1.8
  firebase_storage: ^13.0.4
  firebase_core: ^4.2.1

The AppFrameworkInfo.plist has a bit:

  <key>MinimumOSVersion</key>
  <string>12.0</string>

I collect this file is generated, I have not tried altering it.

When establishing the app it was required to maneuver a file into my venture’s Flutter listing from my Flutter set up. I feel this was Flutter.xcframework.

I’ve tried a full clear of Flutter however the problem persists. App works positive on Android telephones.
