Blurred and Overly-Shadowed Sprites

[joris-prl]

Description

Hello,

I'm currently using the flutter-vector-map-tiles package to display a vector map with Maptiler's "streets" style. However, I'm encountering a rendering issue with the sprites, which appear blurred and have an overly strong shadow.

Code

  void _readStyle() async {
    Style lightStyle = await StyleReader(
      uri: 'https://api.maptiler.com/maps/streets-v2/style.json?key={key}',
      apiKey: 'XXXXXXXX',
    ).read();
    this.lightStyle = lightStyle;
  }

        final VectorTileLayer tileLayer = VectorTileLayer(
          theme: lightStyle.theme,
          sprites: lightStyle.sprites,
          tileOffset: TileOffset.DEFAULT,
          tileProviders: lightStyle.providers,
          layerMode: VectorTileLayerMode.vector,
        );

pubspec.yaml
(Relevant dependencies only)

dependencies:
  flutter_map: ^6.0.0
  vector_map_tiles: ^7.3.1

Expected Behavior

I expect the sprites to be displayed sharply, without blur or excessive shadow, consistent with the standard appearance of Maptiler's "streets" style.

Question: Do you have any suggestions for resolving this rendering issue? Is this a known problem, or are there specific settings I could adjust to improve the appearance of the sprites?

Thank you in advance for your help!

I'm not sure what's happening here. It's working better with the mapbox streets theme, see https://github.com/greensopinion/flutter-vector-map-tiles-examples

To troubleshoot you could look into what's different between the two themes. E.g. does the theme you're using have a different sprites json?
This could be a good place to start: https://github.com/greensopinion/dart-vector-tile-renderer/blob/85261f80344ca1d521bacfcb0ef58040720662f7/lib/src/themes/sprite_reader.dart#L8
