MethodChannelGoogleMapsFlutter class Null safety

An implementation of GoogleMapsFlutterPlatform that uses MethodChannel to communicate with the native code.

The google_maps_flutter plugin code itself never talks to the native code directly. It delegates all those calls to an instance of a class that extends the GoogleMapsFlutterPlatform.

The architecture above allows for platforms that communicate differently with the native side (like web) to have a common interface to extend.

This is the instance that runs when the native side talks to your Flutter app through MethodChannels, like the Android and iOS platforms.
