onStyleLoadedCallback fires (n - 1) times the map has been loaded

[JoelGG]

I currently need to navigate to a page containing a MapboxMap, and as suggested in the documentation I'm using onStyleLoadedCallback to generate and add all annotations for the map. Unfortunately I have noticed that on first load onStyleLoadedCallback does not fire, and on every subsequent navigation to the map it fires n times for however many times I have navigated to it (after the first navigation to it)

@JoelGG Thank you for the report. On what platform (android/iOS/web) and with which flutter and plugin version does this happen?

[JoelGG]

@m0nac0 thank you for your reply. This is on iOS and with the latest version of flutter-mapbox-gl available on pub.

[m0nac0]

@JoelGG Thank you. Might be related to #347 and/or #226 (?)

The fact that callback fires more than once points to a memory leak.
#389
#370
#226

[m0nac0]

@AAverin I have very little iOS dev experience, do you happen to have tested #370 and know if it fixes these issues?

[AAverin]

@m0nac0 I also have very little iOS experience.
From what I see in the PR, it users weakReference to avoid capturing and holding the reference inside. Not sure if it is the problem exactly.
At the moment my app is barely usable on iOS due to map issues. I will try to take a look once I have time, but would be best if someone who has more iOS experience could check.
If the iOS SDK is working fine, then the issue should lie in the integration layer somewhere.

@m0nac0 could this be related? Was closed recently and probably is not yet updated in Flutter version: mapbox/mapbox-gl-native-ios#172
I will test on real device today

[AAverin]

This seems to still be an issue on a real device.
onStyleLoadedCallback is not called reliably on iOS

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

Hopefully all style loading issues were resolved in latest PRs
