check method

Future<int> check(
  1. DownloadableRegion<BaseRegion> region
)

Check how many downloadable tiles are within a specified region

Returns the number of tiles.

Implementation

Future<int> check(DownloadableRegion region) => compute(
      region.when(
        rectangle: (_) => TileCounters.rectangleTiles,
        circle: (_) => TileCounters.circleTiles,
        line: (_) => TileCounters.lineTiles,
        customPolygon: (_) => TileCounters.customPolygonTiles,
      ),
      region,
    );
