Line Style Layer

The LineStyleLayer is either used by the map style or can be added to the map programmatically to symbolize data on the map.

Basic Usage

late final MapController _controller;

@override
Widget build(BuildContext context) {
  return MapLibreMap(
      options: MapOptions(center: Position(9.17, 47.68)),
      onMapCreated: (controller) => _controller = controller,
      onStyleLoaded: (style) async {
        final geojsonLine = await rootBundle.loadString('assets/geojson/path.json');
        await style.addSource(
          GeoJsonSource(id: 'Path', data: geojsonLine),
        );
        await style.addLayer(
          const LineStyleLayer(
            id: 'geojson-line',
            sourceId: 'Path',
            paint: {'line-color': '#F00', 'line-width': 3},
          ),
        );
      }
  );
}
