如何在flutter中制作像谷歌地图这样的可滚动控件？

dependencies:
  google_maps_flutter: ^2.0.10

import 'package:google_maps_flutter/google_maps_flutter.dart';

GoogleMap(
  initialCameraPosition: CameraPosition(
    target: LatLng(37.7749, -122.4194), // 初始位置的经纬度
    zoom: 12.0, // 初始缩放级别
  ),
)

Marker(
  markerId: MarkerId('marker_1'),
  position: LatLng(37.7749, -122.4194), // 标记的经纬度
  infoWindow: InfoWindow(title: 'Marker 1'), // 标记的信息窗口
)

Scaffold(
  appBar: AppBar(
    title: Text('Google Maps'),
  ),
  body: GoogleMap(
    initialCameraPosition: CameraPosition(
      target: LatLng(37.7749, -122.4194),
      zoom: 12.0,
    ),
    markers: Set<Marker>.of([marker]),
  ),
)
