Flutterengine get Pluginregistry

注册原生组件

class MapPlug {
    companion object {
        fun registerWith(flutterEngine: FlutterEngine) {
            val shimPluginRegistry = ShimPluginRegistry(flutterEngine)

            val key = MapPlug::class.java.getCanonicalName()
            if (shimPluginRegistry.hasPlugin(key)) return

            val registrar = shimPluginRegistry.registrarFor(key)

            val mapVF = MapVF(flutterEngine.dartExecutor.binaryMessenger, StandardMessageCodec.INSTANCE)

            registrar.platformViewRegistry().registerViewFactory("GoogleMapView", mapVF)
        }
    }

}

registry 改为 flutterEngine，然后使用

val shimPluginRegistry = ShimPluginRegistry(flutterEngine)

MainActivity中

class MainActivity: FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

    }

    override fun configureFlutterEngine(flutterEngine: FlutterEngine) {
        super.configureFlutterEngine(flutterEngine)

        GeneratedPluginRegistrant.registerWith(flutterEngine)
        MapPlug.registerWith(flutterEngine)
    }

}
