VectorMB Tiles is a Flutter plugin for working with Mapbox Vector Tiles in FlutterMap.

By extending VectorTileProvider and specifying VectorMBTiles as the argument of MemoryCacheVectorTileProvider to delegate, it can operate at high speed in memory.

Add the package with the following command

flutter pub add vector_mbtiles

refer to the following. See /example folder for details

VectorTileLayerWidget(
    options: VectorTileLayerOptions(
        theme: Theme,
        tileProviders: TileProviders({
            'openmaptiles': VectorMBTilesProvider(
                mbtilesPath: '/path/to/mbtiles',
                maximumZoom: 18)
        })
    ),
)

Added support of reading uncompressed tiles from database. This could speed up loading of tiles on low power devices.

To use this option supply TileCompression.none to the constructor of VectorMBTilesProvider class

VectorMBTilesProvider(
  mbtilesPath: _basemapPath(),
  // this is the maximum zoom of the provider, not the
  // maximum of the map. vector tiles are rendered
  // to larger sizes to support higher zoom levels
  maximumZoom: 15,
  // option to use map with uncompressed tiles
  tileCompression: TileCompression.none)

Added sqflite_common_ffi package to enable work on Linux and Windows.
