PathSegment class sealed

Base class for path segment primitives.

Path segments represent the building blocks of connection paths. Each segment defines how to draw from the current point to end, and knows how to generate its own hit test rectangles.

Available Segment Types

• StraightSegment: Direct line to endpoint
• QuadraticSegment: Quadratic bezier curve (one control point)
• CubicSegment: Cubic bezier curve (two control points)

Usage Example

final segments = <PathSegment>[
  StraightSegment(end: Offset(100, 50)),  // Horizontal segment
  QuadraticSegment(
    controlPoint: Offset(100, 75),
    end: Offset(100, 100),
    generateHitTestRects: false,  // Corner already covered by adjacent segments
  ),  // Rounded corner
  StraightSegment(end: Offset(60, 100)), // Vertical segment
];
