   The blanking appears to originate in the native Android Maps SDK [...] From the plugin's Dart API there is currently no flicker-free way to invalidate a tile overlay on Android at all

   It's not clear to me why you've added "from the plugin's Dart API" here if the behavior you are describing is from the native SDK. Can you provide code that achieves the behavior you want when using the SDK directly?

   Suggested resolutions, in order of preference:

   1. Make the Android implementation match iOS, e.g. by internally double-buffering: create a replacement native overlay with the same provider, and remove the old one once the new one has rendered.

   Requests for changes in behavior of the native SDK need to be filed against the SDK, rather than against the Flutter wrapper.

   2. At minimum, document the platform difference on GoogleMapController.clearTileCache

   Based on the description here, it seems like this is the only part of the request that can be done in the plugin, so retitling. If there is a call that has the behavior you want, please provide that information and we can adjust the scope.
