BubbleShape class

A shape that creates speech bubble or tooltip-like containers with an arrow.

BubbleShape generates geometric paths for bubble shapes that resemble speech bubbles or tooltips. The bubble consists of a rounded rectangle with an arrow (tail) that can be positioned on any of the four sides.

The bubble's appearance can be customized with:

• Arrow position (bottom, top, left, right)
• Border radius for rounded corners
• Arrow dimensions (height and width)
• Arrow position along the edge (as a percentage)

Example usage:

// Create a bottom-positioned speech bubble
BubbleShape(
  position: BubblePosition.Bottom,
  borderRadius: 12.0,
  arrowHeight: 10.0,
  arrowWidth: 15.0,
  arrowPositionPercent: 0.5,
)

// Create a left-positioned tooltip
BubbleShape(
  position: BubblePosition.Left,
  borderRadius: 8.0,
  arrowHeight: 8.0,
  arrowWidth: 12.0,
  arrowPositionPercent: 0.3,
)
