onStyleLoadedCallback invoked multiple times

[AAverin]

Is there a guarantee that onStyleLoadedCallback will be invoked only once to indicate that the map is ready or it can be invoked multiple times?
At the moment it gets invoked 7 times for me when map is created and I can't understand why.

@AAverin On what platform and with which kind of style are you experiencing this? I'd expect it to be only invoked once but as far as I know that's not something we explicitly guarantee.

This callback is called every time you change the map style and this is been loaded

@m0nac0 on android, will need to check on ios.
I am not changing my map style and just using mapbox streets on map init

[AAverin]

OK, I have found what's the problem.
SDK is fine, problem is that I am using navigator to replace a route and looks like MapBox instance stays alive in the Route that there before and they pile up with new routes replacements.

This kind of brings me back to #245
What would be the right way to do this?

My use case. I have lots of markers on the map and I want to have a route in the app that will open the map tab and focus on a specific marker. I should be able to do this from any screen, which is why I am now using Navigator.

[AAverin]

Same problem happens if I just have multiple different maps on different screens.
I leave the screen, go to another one with a map, but the old map instance is still alive, it seems.
There at least should be a way to destroy mapbox properly.

[AAverin]

Looks like added markers also persist between different maps as if either nothing was destroyed or there is indeed a single map in the background and I should expect this on the flutter side when using multiple maps - clear map instance between screens, expect multiple calls to onMapCreated and onStyleLoaded.

Anything else to expect?

[andrea689]

#315 should fix it

Try to use master branch

@andrea689 Indeed, works great on master, no longer multiple callbacks and markers are also working per map instance.
Thanks
