WebTiledLayer tile loading indication

[dev4567]

Is there a way to indicate concrete tile is being loaded? Some tiles could be quite massive and users with poort network connection should know the tile is actually loaded and not just empty or "stuck"

You can set how a tile request that returns 'No Data' is resampled by setting noDataTileBehavior  property on the WebTiledLayer,
This lets you choose what to display where the tile should have been displayed,

NoDataTileBehavior.UpSample - Resample the pixels from a lower level of detail tile.

NoDataTileBehavior.Blank - The 'NoData' pixels will show the raster picture as being blank (or disappearing).

NoDataTileBehavior.Show - This will show the raster picture with the text 'No Data' stamped over it once you pass the lowest level-of-detail scale.

unfortunately, this doesn't help when the map is being loaded the first time

You can try using the layerViewStateChanged  callback on the GeoView that gives you the LayerViewStatus on individual layers in the MapView. When the tiles in the WebTiledLayer are not successfully loaded you will get the Warning LayerViewStatus. If you get that then the LayerViewState.error property will provide more details about the specific problem which was encountered.

This is inaccessible in compose toolkit -> please, add same the shared flow functionality to the `GeoViewProxy` – currently there is only `getLayerViewState` which is not that convenient to use
