I’ve started to get an error starting today saying:

Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.

This error arises after/during I build the .apk binary of my app. I tried the solution explained in Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15 but did not succeed. My build.gradle files does not contain such line to add/edit the Kotlin version information. I use Flutter project build with VS Code. Both the build.gradle files (found in android/app/build.gradle and android/build.gradle) does not contain such provision.

Here is the flutter doctor output:
