google_maps_flutter Memory Leak when map is shown, memory allocated never dispose #35243
Description
Steps to Reproduce
Problem:
I have been facing a critical issue with the GoogleMap plugin, the problem is on iOS devices, when the GoogleMap widget is RENDERED (please note that the problem is not when instantiating the object) it appends a lot of memory to the current app, when the map is disposed, that memory allocated never goes away, it keeps growing as the Map is called to be shown.
Why it is a critical issue:
This is a critical issue because on iOS when the app reaches approximately 1gb the OS closes the app unexpectedly, and its a blocker to launch our app to production.
Replicate:
Use the memory monitor of XCode, not the dart tools,
This is not replicable on the emulator, only on real iOS devices, you can use the google_maps_flutter example to test.
Request:
Please let us know if you can replicate the issue just to be sure that this is on your scope
