I have two recommendations for this issue, also did you try flutter run or did you just try ./gradlew build ?

1st Recommendation:

• Run flutter clean

• then try to sync the Gradle version in android/gradle/wrapper/gradle-wrapper.properties

  to the latest available build.

• Right now, I'm using gradle-8.5-all.zip on Flutter 3.29.2

If the 1st recommendation doesn't work, I recommend re-building the android folder, many times when I was building on iOS when I switched back to Android on a specific project that helped too, I've had some problems with versioning. Simply re-building the Android folder could solve the issue:

2nd recommendation:

• Delete android/

• Run flutter create --platforms=android .

Lastly, if this doesn't help can you please provide flutter doctor ?
