Problem with Flutter fastlane with flavors

Question

Has anyone used fastlane with flutter and two flavors? I have a flutter application with two schemes App_A and App_B. I am trying to configure fastlane for configuration App_A. My project:

• configuration: (Debug-App_A, Debug-App_B, Release-App_A, Release-AppB)
• targets: (App_A, App_B)
• scheme: (App_A, App_B)

List of command I do:

• flutter clean
• flutter build ios --flavour App_A
• cd ios
• fastlane ios beta

output:
