FollowsUserLocation 不适用于 Android (react-native-maps)

Question

地图会跟随用户在 iOS 上的位置，但不会跟随 Android 上的用户位置。用户的位置显示在地图上，"my location" 按钮也可以正常工作。

Android 不跟随位置可能是什么问题？

<MapView
  style={styles.map, { flex: 1, marginBottom: this.state.marginBottom }}
  onMapReady={this._onMapReady}
  initialRegion={initialRegion}
  showsUserLocation={true}
  followsUserLocation={true}
  showsMyLocationButton={true}

我按照这个 https://github.com/react-community/react-native-maps/issues/1038#issuecomment-404223242 设法解决了这个问题。这正是我想要实现的。地图默认跟随用户位置，但拖动地图时将禁用跟随。

然后我在 https://github.com/react-community/react-native-maps/issues/209#issuecomment-350907665 之后为当前位置创建了一个按钮。使按钮设置 followsUserLocation 回到 true。
