Solution

  • The following steps will fix the problem (update to new renderer in kotlin project):

    1. Add this line to your app's build.gradle:

      implementation 'com.google.android.gms:play-services-maps:18.0.2'

    2. Import these lines to MainActivity.kt:

      import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.MapsInitializer.Renderer
import com.google.android.gms.maps.OnMapsSdkInitializedCallback

    3. Add MapsInitializer.initialize(applicationContext, Renderer.LATEST, this) in your MainActivity onCreate method.

    Implement OnMapsSdkInitializedCallback interface for verify the new renderer. example (MainActivity.kt):

    package com.example.application

import android.os.Bundle
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugin.common.MethodChannel
import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.view.FlutterMain
import android.os.Build;
import android.view.WindowManager
import android.util.Log;
import com.google.android.gms.maps.MapsInitializer
import com.google.android.gms.maps.MapsInitializer.Renderer
import com.google.android.gms.maps.OnMapsSdkInitializedCallback


class MainActivity: FlutterActivity(), OnMapsSdkInitializedCallback{
    override 
    fun onCreate(savedInstanceState: Bundle?){
        super.onCreate(savedInstanceState);
        MapsInitializer.initialize(applicationContext, Renderer.LATEST, this)
    }

    override fun onMapsSdkInitialized(renderer: MapsInitializer.Renderer) {
      when (renderer) {
        Renderer.LATEST -> Log.d("NewRendererLog", "The latest version of the renderer is used.")
        Renderer.LEGACY -> Log.d("NewRendererLog","The legacy version of the renderer is used.")
      }
    }
}
    1. Run & Check the logs, you should see these lines:

    D/MapsInitializer: loadedRenderer: LATEST D/NewRendererLog: The latest version of the renderer is used.
