Reproduce the failure using the affected gcr.io/cloud-builders-community/flutter image and the shown gcloud builds submit --config cloudbuild.yaml . command. Start with the Docker build step running flutter doctor --android-licenses and verify that the completed image can locate sdkmanager and process Android license acceptance without the reported errors.
