Memory doesn't release when after map render

[thuydao]

For example, I go to user interface > back to main screen > go to user interface again. The memory not reduce.

I have the same problem.

App is crashing on ios when using the map a lot.
It is very easy to reproduce in example app.
Just enter one page with map, go back, enter again, go back.
Repeat several times and app will crash.

In my case on iphone 6s:

• open and close Full screen map 47 times, then crash
• open and close User interface 28 times, then crash

In my project it takes 16-18 times to open and close map page before it crashes.
The only log from xcode that I had after app crashing was:
Message from debugger: Terminated due to memory issue

@thuydao @kleeb Is this only on iOS?

[kleeb]

Yes. I reproduced that even on the example app

This seems to happen only on iOS. Does anyone know if this happens in the flutter-mapbox-gl plugin or in the native code?

Inspecting this with XCode instruments you can see the MapboxMapController does not get cleaned up. The reference count keeps going up.
