BMFHeatMap.fromMap constructor

BMFHeatMap.fromMap(
  1. Map map
)

map => BMFHeatMap

Implementation

BMFHeatMap.fromMap(Map map)
    : assert(map != null,
          'Construct a BMFHeatMap，The parameter map cannot be null'),
      assert(map.containsKey('data')) {
  if (map['data'] != null) {
    data = new List<BMFHeatMapNode>();
    map['data'].forEach((v) {
      data.add(BMFHeatMapNode.fromMap(v as Map));
    });
  }

  radius = map['radius'];
  opacity = map['opacity'];
  gradient =
      map['gradient'] == null ? null : BMFGradient.fromMap(map['gradient']);
