Step 2 – Create bundle release via following commands
cd android
./gradlew bundleRelease
This should update your bundle file in your android/app/build/outputs/bundle/release
Right click to check properties if the file is updated with new version.
In case if the above command doesn’t update .aab file then follow the following steps.
cd android
./gradlew clean
./gradlew bundleRelease
This should update the .aab file.
