[BUG] Cannot run Flutter app on real device

[divan]

Description

Tried to use maestro-runner with simulator - works great. Connected iPad via USB, installed Flutter app via flutter run -d $MY_IPAD_UUID - it was installed. Then ran maestro-runner, so app flashing and disappearing immediately and got this:

maestro-runner --platform ios --team-id $MY_TEAM_ID --device $MY_IPAD_UUID--app-file ../app/build/ios/iphoneos/Runner.app test --output reports flows/test.yaml

  maestro-runner 1.0.9 - by DeviceLab.dev
  Fast, lightweight Maestro test runner
