createSegments method

@override ({List<PathSegment> segments, Offset start}) createSegments(ConnectionPathParameters params)

Creates segments for this connection, using control points if available.

This method is the main entry point called by the rendering system. It delegates to either:

• createSegmentsThroughWaypoints if control points are provided
• createDefaultSegments if no control points exist

Implementation

@override
({Offset start, List<PathSegment> segments}) createSegments(
  ConnectionPathParameters params,
) {
  if (params.controlPoints.isNotEmpty) {
    // Manual mode: use control points as waypoints
    // IMPORTANT: Include start and end points in the waypoints list
    final waypoints = createWaypointsWithEnds(params.controlPoints, params);
    return createSegmentsThroughWaypoints(waypoints, params);
  } else if (!requiresControlPoints) {
    // Algorithmic mode: use default segment creation
    return createDefaultSegments(params);
  } else {
    // Style requires control points but none provided
    // Fall back to simple straight line
    return (
      start: params.start,
      segments: [StraightSegment(end: params.end)],
    );
  }
}
