当我切换黑白两个谷歌地图标签时，它会给出这些错误

Err home google map : PlatformException(error, Error using newLatLngBounds(LatLngBounds, int): Map size can't be 0. 很可能，地图视图的布局尚未发生。要么等到布局发生，要么使用 newLatLngBounds(LatLngBounds , int, int, int) 允许您指定地图的尺寸​​。, null, com.google.maps.api.android.lib6.common.apiexception.c: Error using newLatLngBounds(LatLngBounds, int): Map size can' t 为 0。很可能，地图视图的布局尚未发生。要么等到布局发生，要么使用 newLatLngBounds(LatLngBounds, int, int, int) 来指定地图的尺寸​​。

超出 FrameTime I/chatty (1275) 中的样本计数：uid=11060(com.enbake.entracker) androidmapsapi-相同的 2 行

多次获得这个

MissingPluginException（在通道 plugins.flutter.io/google_maps_5 上找不到方法 polylines#update 的实现）
