I'm not sure about this on remove. Maybe just mapView?.viewport

I don't understand the comment exactly - mapView
doesn't need optional chaining if acquired in the withMapView
callback. What's the concern?

First it should be map.withMapView { }
we're in remove so we have a RNMBXMapView we're removing from, passed in as argument .
Second if mapView of RNMBXMapView is null then what was the satusObserver was attached to? Why do we need to remove?
So I think withMapView is unnecessary in this case. Likely not harmful but you have the check carefully as it could easily keep the camera object alive, until we'll have a mapView. Which doesn't sound right, but probably no leak here.

I don't have a strong sense of the implications of the callback architecture (_mapCallbacks.append(callback)
, etc.).
We can do
map._mapView.viewport.removeStatusObserver(self)
but since _mapView
is force-unwrapped, I'm not sure if it could be nil when acquired that way. It'd be the only place in the camera module where map.mapView
is referenced that way. Do you prefer the map._mapView
syntax?

I've found that I have more consistant results by using zoom: .zero
. If zoom is set on this camera is seems to effect the positioning.

@mfazekas @naftalibeder I'll aim to make a demo this afternoon of why i've highlighted this.. but when moving the camera with setCamera from a centerCoordinates position to setCamera with bounds it seems that zoom is applied to the final position. Adding this zoom: .zero
looks to fix this problem thou I need to look at why.

why do we use coordinatePadding and not camera padding?
