It's failing because you have integrated some package in your application that is not compatible with the gradle version you have been using.
On Android studio, you can check your gradle version by : Open the project (If you are using Flutter, my suggestion would be to Click Open Existing project and then just choose the android directory inside your project's root) > File > Project Structure
You can either make that package compatible with your version of gradle (Probably be editing its MainActivity.kt file)
OR
Use a lower version of gradle (You can change this by going to andoid/build.gradle..Look for a line like this : classpath 'com.android.tools.build:gradle:4.1.0' Here 4.1.0 means gradle v6.7
Try a few values and If you are lucky everything would work just fine! :)
