HeatmapConfig class

Configuration class for heatmap properties, supporting multiple map platforms.

Constructors

HeatmapConfig.new({double heatmapRadius = 20.0, double heatmapOpacity = 0.3, double heatmapIntensity = 1.0, HeatmapInterpolation interpolationMethod = HeatmapInterpolation.linear, List<Color> colors = const [Colors.blue, Colors.green, Colors.yellow, Colors.orange, Colors.red], List<double> stops = const [0.2, 0.4, 0.6, 0.8, 1.0], List<double> zoomStops = const [0.0, 5.0, 10.0], List<double> zoomWeights = const [0.1, 0.5, 1.5], HeatmapReference reference = HeatmapReference.heatmapDensity, List<LatLng> points = const []})
