I am trying to make a flutter app, which upon entering mobile number sends and otp verfication code, using firebase authentication but later an error showed up:

Execution failed for task ':app:checkDebugDuplicateClasses'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable".
Resolved it by doing this "dependencies{
    implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.22"))
    //..
}"
Then another error showed up : "e: C:/Users/dhruv/.gradle/caches/transforms-3/f495eaf6341c52f3f63244e9b688886b/transformed/jetified-recaptcha-18.4.0-api.jar!/META-INF/third_party.java_src.protobuf.current.java.com.google.protobuf.kotlin_shared_runtime.kotlin_module: 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.

Error: Gradle task assembleDebug failed with exit code 1

I have tried doing this :

buildscript {
    ext.kotlin_version = "1.9.0"
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.1.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // Other dependencies
    }
}

but the error still isn’t solved and the line :classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" is showing a warning that “Kotlin version that is used for building with Gradle (1.9.0) is not properly supported in the IDE plugin (1.8)”. I have tried syncing as well but it’s still not working. PLs guys help me out here!!!????
