Flutter Android - Gradle task bundleRelease failed with exit code 1

Question

I am trying to run the command "flutter build appbundle --verbose" to generate the android version of my app and i am receiving the error "Gradle task bundleRelease failed with exit code 1".

I don't know yet a lot of things about gradle and your dependencies to each package, I have read some stack-overflow answers, refactored the bundle.properties file among other things without success. Here is my build information:

flutter build appbundle --verbose part of output

Do you all have any suggestion to solve this problem?

I have also tried to migrate to AndroidX without success.

Solution

It's a minor issue, Run "Flutter clean" and then "Flutter build appbundle" or "Flutter build apk".

That should fix the issue
