valueColorMap
→ Map<T, Color>?
-
Provide a map that defines how the cell value in 'selectedMap'
should change color in the heatmap
This map is generally used in color maps when some colors in the map
are too close to the value colors, making it difficult to distinguish them
e.g. colorMap = {0: Colors.white, 10: Colors.black, 20: Colors.blue}
valueColorMap = {0: Colors.Black, 10: Colors.white}

final
-
weekLabelValueBuilder
→ WeekLabelValueBuilder?
