[FlutterFirebaseMessagingPlugin] Application.kt: (13, 44): Unresolved reference: registerWith

[m-amin]

Getting error when running app in flutter. Seems that error come from firebase messaging plugin, anyone had this issue before? Here is details of the error message:

`path/xxx/Application.kt: (13, 44): Unresolved reference: registerWith

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> Compilation error. See log for more details`

Here is my Application.kt file:

class Application() : FlutterApplication(), PluginRegistry.PluginRegistrantCallback {
    override fun registerWith(registry: PluginRegistry?) {
        val key: String? = FlutterFirebaseMessagingPlugin::class.java.canonicalName
        if (!registry?.hasPlugin(key)!!) {
            FlutterFirebaseMessagingPlugin.registerWith(registry?.registrarFor("io.flutter.plugins.firebase.messaging.FlutterFirebaseMessagingPlugin"));
        } 
    }
}

Android/buld.gradle:

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