I have placed a marker on my map which is in a form of image. Now when the photo is clicked in my application using the latitude and longitude, it gets displayed on map. My question is when more than two pictures are clicked on same place then they get overlapped on each other, how can I view both the images? Below is the image provided which I want as a final result.

Is there any way to get a map snapshot with a tile overlay, for example for sharing or widgets?
MKMapView contains an addOverlay function that adds an MKTileOverlay overlay to the map. This is easy to do.
It is not possible to get a snapshot of such a composite view.
To get a snapshot of the map I used MKMapSnapshotter, which simply supplies a snapshot of any map slice. However, MKMapSnapshotter only gives the original map. If I need to add a layer, I have to draw it into the map snapshot. For simple layers like icons this is easy. But I don't know how to do it at all with a tile overlay.
I suppose I need to use MKTileOverlay to get an overlay image for the same area as the map snapshot. It is not a problem to merge such images. Unfortunately I don't know how to get it.
How to get a map image with a tile overlay?
I have this basic application where with a help of a REST API backend I fetch some custom locations(with lat long values).
I call this GET api, with a given boundary of NE and SW latlong values. So after the network call executes it gives me a list of custom markers where then I draw the google map on the screen and draw(overlay) these markers on top of the map.
The full set of markers will be fetched as explained above in init() method when Home Screen loads. so when user sees the map the custom markers are already there and visible.
This approach takes time when there are few hundred of markers coming from that GET api call.
Instead I want to modify the app so. when user sees the map view, it should inly load markers in that visible screen area(of the map) only. and when user moves from that area to another then the markers which should be in that new area comes to visible. and so on and so forth.
I am not sure of how to execute such a thing with flutter.
Can I get some guidance help on this?
The map I'm making has the labels for markers overlapping unless I zoom in so much that only a small section of the map is visible. I'm presenting the map as one static picture of the entire state that is supposed to show all of the marker labels. Is there a way I can display a view of the map that will show the entire state I'm trying to display in one image with all of the marker labels visible? Here is what it looks like now
I've been long time searching for a way to achieve placing pins on an image just like the mapview, but have not been able to do this yet. I thought someone could give a clue as what kind of class is used in this picture.As you can see everything is like MKMapView with Annotation pins and callout except for that it's not a map but an ordinary image. How can I achive the same thing?
Yeah, basically a matter of creating the pin image, then placing image views of that image over your background image. Create the image view, set it's position as needed, and call addSubview from the background image.
You can try a simple way, first find out the position of the user tap on the image or screen. Then place that pin image on that tap position in such a manner the height of the pin image should point the y axis of the tap. If you want to store that data then store it in some array or file and you can also save that image (the map containing pins) as png.
I am trying to build 15-puzzle game.
Here I need to swap a blank image with a clicked on image. I would like to know how to swap these images.
I have stored the co-ordinates of the two images,but don't know the format to identify the blank image and then set its origin to clicked image.
Present each tile as a CALayer. To swap two tiles, set each layer's position to the other's position.
