BarColorPicker class

A widget that allows users to pick colors from a gradient bar.

The BarColorPicker widget provides a horizontal or vertical bar with a thumb that users can drag to select a color from a gradient.

Example Usage:

BarColorPicker(
  pickMode: PickMode.color,
  length: 200,
  initialColor: Color(0xffff0000),
  thumbColor: Colors.black,
  colorListener: (colorValue) {
    // Handle the selected color change here
  },
)
