This error could be occurred due to mismatch between gradle version and Android SDK version. I recommend to figure it out by opening just the "android" folder (not the whole Flutter project) with Android Studio. After opening, the Android Studio will automatically download and install the gradle.

If there is any issue related to conflict between gradle version and Android Studio SDK version, you will get specific error message and recommendations in the build section. Then you can follow the recommendations to solve the conflict.

If it builds the gradle successfully, your problem probably will be solved.
