    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.1.2'
        // START: FlutterFire Configuration
        classpath 'com.google.gms:google-services:4.3.10'
        // END: FlutterFire Configuration
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"

Open android/build.gradle file and increase the version of ext.kotlin_version to a compatible version of Kotlin. Can you try these steps in order?

ext.kotlin_version = '1.3.50'

TO

ext.kotlin_version = '1.4.32'

Your build.gradle file may look like this:

buildscript {
    ext.kotlin_version = '1.4.32'
    repositories {
        google()
        mavenCentral()
    }

Now hit the command below:

flutter clean

Now run your app again.

You can also benefit from here: 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
