vector_map_tiles high zoom level shows grey map

[jeff-matawan]

Hi,
I was wondering if it was possible to keep showing the last lower zoom level tile if when zooming there aren't any more ?
Maybe this video will explain it more clearly.

I'm using the following code

if (tileProvider != null) {
  return VectorTileLayer(
    theme: widget.mapTheme,
    tileProviders: TileProviders({'protomaps': tileProvider!}),
  );
} else {
  return const SizedBox();
}

Hi @jeff-matawan, yes this is possible by using the maximumZoom parameter in the VectorTileLayer.
See this example as a reference:

flutter_map_plugins/example/lib/vector_map_tiles_mbtiles/page.dart

Lines 67 to 77 in 2a6a678

	VectorTileLayer(
	theme: _theme,
	tileProviders: TileProviders({
	'openmaptiles': MbTilesVectorTileProvider(
	mbtiles: _mbtiles!,
	),
	}),
	// do not set maximumZoom here to the metadata.maxZoom
	// or tiles won't get over-zoomed.
	maximumZoom: 18,
	),
