getRatioPoint method

Point getRatioPoint(
  1. Segment segment,
  2. double r
)
override

Calculate projection point on a segment segment segment of calculation Segment r division ratio Returns ratio point Point

Example:

// Get point at specific ratio
double ratio = 0.5;
Point ratioPoint = GeometryUtils.getRatioPoint(segment1, ratio);
print("Point at ratio $ratio: (${ratioPoint.x.toStringAsFixed(2)}, ${ratioPoint.y.toStringAsFixed(2)})");

Implementation

    final _segmentHandle = navigine_sdk_flutter_Segment_ToFfi(segment);
    final _rHandle = navigine_sdk_flutter_double_ToFfi(r);
