Flutter – Error: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1

I am encountering an error to my flutter project. I wanted to add firebase service to my flutter project. However when I am following the steps from Firebase by adding the google-json file to my android/app directory and also adding the codes dependencies to both project level and app level build.gradle file. The error of imcompatible version of Kotlin prompted up.

The errors message are

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.compilerRunner.GradleCompilerRunnerWithWorkers$GradleKotlinCompilerWorkAction
