Show old tiles until new ones are downloaded

[vinicentus]

When a user zooms in enough, new, more zoomed in tiles are loaded and displayed. Would it be possible to show the images of the current layer until the new pictures are loaded instead of just showing a grey map while the new tiles are loading?

Yes, we should always keep the old tiles on the screen when zooming.

I have this issue too,
When it's going to be fixed?

[johnpryan]

Unfortunately, I don't have an estimate on when I'll have time to fix this

That said, we accept pull requests!

What is the work required here?

I have this issue too, when the scrolling happens the tiles which are loading turn white which is bad UX

[johnpryan]

I think this will require some additional investigation into Leaflet's tile fetching strategy. I assume it eagerly loads the tiles at the surrounding zoom levels

[aswinmohanme]

Just glancing over the code I think we can use the placeholder field on the FadeInImage with the previously loaded tile, if we can pass in the old coords right ?

I have the same issue, the usability is not good.

[vinicentus]

Yes, we should really try to fix this, it shouldn't be too hard. I can't make any promises but if I have time I could look into doing what @aswinmohanme suggested.

Guys you can use google_maps_flutter (Google Supported Officially) instead.
It is made alongside flutter release v1.0.

@imaNNeoFighT flutter_map has also great advantages towards google_maps_flutter or is it already possible that each marker on the map is also a widget?

@RaimundWege
I think it's not possible to put a widget as a marker,
And maybe it is Google policy to prevent it because also in android you can't directly put a View as Marker on GoogleMap,
And in android to achieve this we had to use a projection that supported by GoogleMap that converts latitude, longitude to screen pixel position, maybe in future, this functionality added to FlutterGoogleMap (or maybe it exists already).
