Given two flavor dimensions: app and type
example being in the app dimensionprod being in the type dimension
and Flutter build command: flutter build appbundle --release --flavor exampleProd --verbose flutter_tools is looking for the AAB file in:
build/app/outputs/bundle/release/app.aabbuild/app/outputs/bundle/release/app-release.aabbuild/app/outputs/bundle/exampleprodRelease/app.aabbuild/app/outputs/bundle/exampleprodRelease/app-exampleprod-release.aab
And it's actually located inbuild/app/outputs/bundle/exampleProdRelease/app-example-prod-release.aab therefore the command fails to complete sucessfully.
Gradle build failed to produce an .aab file. It's likely that this file was generated under (...)/build, but the tool couldn't find it.
