Issues with Google Maps enabled App using flutter framework on Android Studio

Question

Trying to build a cross platform connected device Google Maps enabled App using flutter framework on Android Studio without success. The flutter run works seemlessly until device dependency google_maps_flutter: is used under pubspec.yaml. AndroidX is enabled in the gradle. So far trying only on the emulators.

The warning message furnished below seems appropriate, but the steps given in the link are difficult to realize. Build keeps on searching for version 5.4.1. The gradle wrapper is configured for gradle-4.10.2 and the gradle as com.android.tools.build:gradle:3.2.1. The Android version and SDK toolchains are up-to-date. Need help here.

The terminal warning message:

The plugin `flutter_plugin_android_lifecycle` is built using an older version of the Android
plugin API which assumes that it's running in a full-Flutter environment. It may have undefined 
behaviors when Flutter is integrated into an existing app as a module.The plugin can be 
updated to the v2 Android Plugin APIs by following https://flutter.dev/go/android-plugin-migration.

More error messages:

Project evaluation failed including an error in afterEvaluate {}. Run with --stacktrace for details of the afterEvaluate {} error.

FAILURE: Build failed with an exception.

To pass this error, add below line to app/proguard-rules.pro

-keep class androidx.lifecycle.** { *; }

And add bellow line to app/build.gradle

  lintOptions {
    checkReleaseBuilds false
}
