如何在Flutter中为Google Maps Marker添加动画？

dependencies:
  flutter:
    sdk: flutter
  google_maps_flutter: ^2.0.10
  flutter_google_maps: ^1.1.0

import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';
import 'package:flutter_google_maps/flutter_google_maps.dart';

GoogleMapController? _controller;

void _onMapCreated(GoogleMapController controller) {
  _controller = controller;
}

GoogleMap(
  onMapCreated: _onMapCreated,
  initialCameraPosition: CameraPosition(
    target: LatLng(37.4219999, -122.0840575),
    zoom: 14.0,
  ),
  markers: {
    Marker(
      markerId: MarkerId('marker_1'),
      position: LatLng(37.4219999, -122.0840575),
      infoWindow: InfoWindow(title: 'Marker 1'),
      icon: BitmapDescriptor.defaultMarker,
    ),
  },
),

MarkerAnimationController _animationController = MarkerAnimationController();

void _onMapCreated(GoogleMapController controller) {
  _controller = controller;
  _animationController.setMapController(controller);
}

MarkerAnimationOptions animationOptions = MarkerAnimationOptions(
  startMarkerId: 'marker_1',
  endMarkerId: 'marker_1',
  duration: Duration(seconds: 5),
  curve: Curves.ease,
);

_animationController.addMarkerAnimation(animationOptions);

@override
void dispose() {
  _animationController.dispose();
  super.dispose();
}
