Your project requires a newer version of the Kotlin Gradle plugin.

When I try to deploy th Google Play Store I get a "Failed" message and I found this in the log file

Gradle task bundleRelease failed with exit code 1


Build failed :|
Step 8 script `Build AAB with Flutter` exited with status code 1

Any idea how I could fix that?
