Is there a plugin (like OverlappingMarkerSpiderfier-Leaflet) or does anyone know how to account for polyline overlapping with markers? I am basically trying to avoid situation line this
UPDATE1:
I specifically want the polyline to go around the marker (like an arc) so that its clear to the user that the curved polyline is connecting the end-most markers and middle marker's polylines are then visible
What exactly is the issue with the above? If it's a matter of the markers appearing below the lines, you just need to either
add the markers after you add the lines
or better yet, use leaflet's .bringToFront() and .bringToBack() methods.
Reordering the z index of a feature layer is a pretty straightforward use case, so I don't imagine you'd need a plugin for it.

I'm using google_maps_flutter to display only specific markers on the map. Unfortunately, there are tons of other markers and circles on the map that interrupt the experience (Restaurants, Stores and so on). How can I disable or remove them?
I found out that it can be made by styling the map and removing unwanted parts away. You can also make some sick looking design too. Very useful.

I'm using Leaflet (with omnivore and the MapQuest tile plugins) to display a map with colored polygons. The map and polygons look/work fine, but there are these mysterious blue markers everywhere.
There's nothing in the JS about markers at all, and if I comment out the polygon.addTo(map); line, the markers disappear. So they're definitely related to the polygons, even though they're not directly positioned on the polygons.
Any idea why the markers are appearing, or how I can make them disappear?
SOLVED: It turns out that the problem was that I'm using MSSQL's ".Reduce(n)" function to simplify the polygons (for performance), and if you simplify the polygons too far, the results have "Point(...)" items in them - which leaflet renders as markers!
Now, off to figure out why MSSQL is turning things into points...
Welcome to SO!
Most probably your polygon variable is a Leaflet GeoJSON Layer Group built by the omnivore plugin, and the data you feed it with contains "Point" type geometries.
If you do not specify anything special to handle these points, Leaflet will render them with this default blue marker icon.
In that case, you could simply filter out those point features, whether after omnivore processing (use the ready event) or using a custom GeoJSON Layer Group with its filter option. There should be other posts describing such solutions.
See e.g. Mapbox: Filtering out markers in a Leaflet Omnivore KML layer
If you are not in this case, you would have to provide more information for people to be able to help you. Typically code that you use to build your polygon layer and sample data.
Using leaflet mobile maps, you can easily get "lost" if you zoom in too far or pan in the wrong direction, so I'd like to display some kind of dynamic hint arrows(?) around the edge of the map which point to those offscreen markers. Something like the illustration below which I stumbled on here while trying to find a solution.
You would probably be interested in Leaflet EdgeMarker plugin (demo):
[…] allows you to indicate Markers, Circles and CircleMarkers that are outside of the current view by displaying [a chosen icon (like an arrow)] at the edges of the map.
I try to repeat a marker at the same coordinates when I am moving the map to infinity, in the same way that layers.
example : https://www.mapbox.com/mapbox-gl-js/example/geojson-polygon/
Has anyone found how to do that please?
If it's not possible, conversely is it possible to not repeat layers when you moving the map ?
Thank you
The Link example you provided is not using Markers to render the shaded area. It is using a feature, in this case a polygon, included in a layer (a layer can have many features).
In MapBox the rendered map is made up of any number of layers (including the tile data) which is rendered whenever you scroll or drag to a particular area of the map. For example as you keep dragging to the right in the map it will just keep rendering in the relevant layers and tiles.
The Marker functionality has a different purpose which is as a one off selected point which is useful for a user click or hover interaction.
Screenshot from Mapbox docs:
It seems as though Mapbox won't render given coordinates multiple times on the same map, even if the map is zoomed out far enough to view the same latitude and longitude pairing twice. Is there a way around this?
Use the worldCopyJump option of L.mapbox.map (L.map):
With this option enabled, the map tracks when you pan to another "copy" of the world and seamlessly jumps to the original one so that all overlays like markers and vector layers are still visible.
