A simple function to interpolate between a list of colors

interpolate_colors.dart

  Color interpolateColors(double value, List<Color> colors) {
    assert(value >= 0 || value <= 1, 'value must be between 0 and 1');
    final int colorListLength = colors.length - 1;
    final int maxExpectedIndex = (colorListLength * value).ceil();
    final int minExpectedIndex = (colorListLength * value).floor();

    final Color minColor = colors[minExpectedIndex];
    final Color maxColor = colors[maxExpectedIndex];

    return Color.lerp(minColor, maxColor, value)!;
  }
