• breaking Custom colorScale is removed. Color is now automatically calculated based on Highest ContributionEntry's value as 100% and 0(Zero) as 0%

Before

// Custom color scale
  colorScale: (value) {
    if (value == 0) return Colors.grey[100]!;
    if (value <= 2) return Colors.green[200]!;
    if (value <= 5) return Colors.green[400]!;
    return Colors.green[600]!;
  },

After

// Default color is green like Github
// But you can choose other value.
heatmapColor: HeatmapColor.green,

Now its easy to change color. Just supply the HeatmapColor value.
