geometry_kit 1.2.2

A set of utils that help with geometry (line, circle, triangle, polygon, arc, ring, capsule, bezier, spline, ellipse, rectangle, ray).

1.2.2

• update git hub info

1.2.1

• fix: Line — tightened NaN checks across slope/intercept calculations
• refactor: Quadrilateral and Triangle — clearer getter names for sides and special points
• docs: expanded dartdoc on Circle, Line, Point, Polygon, Quadrilateral, Ring, Triangle, and units
• chore: moved package into geometry_kits_mono monorepo alongside new geometry_kit_widgets

1.2.0

New Classes

• feat: added Rectangle class with AABB constructors (fromPoints, fromCenter, square), containment, overlap detection, diagonal, corners, intersectsLine(), intersectsCircle()
• feat: added Ellipse class with dual radii, area, perimeter (Ramanujan approximation), containment, eccentricity, foci
• feat: added Ray class with origin/direction, pointAt, intersection with Line and Circle
• feat: added Arc class with arc length, sector area, start/end/mid points, parametric sampling, fromDegrees factory
• feat: added Quadrilateral class with classification checks (isParallelogram, isRhombus, isTrapezoid, isKite, isRectangle, isSquare, isConvex), diagonals, center, containment
• feat: added Ring class (annulus) with innerRadius, outerRadius, width, circumferences, containment
• feat: added Capsule class (stadium shape) with medialAxis, radius, boundingBox, endCaps, fromRect() and circle() factories, containment
• feat: added Polyline class (open path) with length, segments, boundingBox, parametric pointAt(), simplify() (Ramer-Douglas-Peucker)
• feat: added Bezier class (quadratic Bezier curve) with parametric pointAt(), split(), boundingBox, length
• feat: added Spline class (Catmull-Rom) with sample(), tangentAt(), toPolyline(), approximateLength()
• feat: added Segment type alias for Line

New Methods on Existing Classes

• feat: Point — added angleTo(), dot(), magnitude, normalized, midPointTo()
• feat: Line — added isVertical, isHorizontal, isParallelTo(), isPerpendicularTo(), translate(), scale(), rotate()
• feat: Triangle — added isScalene, centroid, circumcenter, incenter, contains()
• feat: Polygon — added centroid, isConvex, intersectsLine(), intersectsCircle(), regular() factory
• feat: Circle — added contains(), distanceTo(), intersectsLine(), intersectsCircle()

Bug Fixes

• fix: Point.translate() now correctly translates instead of doubling input (variable shadowing bug)
• fix: Circle.hasPoint() inverted logic — now correctly returns true when point is inside; added type annotation
• fix: Circle.scale() now actually scales radius and center
• fix: Line.getIntersectPoint() checks both segment parameters, preventing false positives
• fix: Line.slope handles vertical lines (returns infinity instead of crashing)
• fix: Line.yIntercept returns NaN for vertical lines instead of crashing
• fix: Line.xIntercept returns NaN for horizontal lines instead of crashing
• fix: Line.hasPoint() uses epsilon-based comparison instead of exact float equality
• fix: Triangle.orthocenter rewritten with vector-based formula — no longer crashes on vertical/horizontal sides
• fix: Polygon.getInnerCentroid() corrected centroid formula using proper shoelace calculation
• fix: Polygon.area now always returns positive value (.abs() applied)
• fix: AngleUtils.minOfArcToRadian() corrected formula (was multiplying instead of dividing)
• fix: removed debug print() left in Triangle.angles

Breaking Changes

• refactor: Shape subclasses now use implements Shape instead of extends Shape
• feat: Polygon transform methods now return Polygon instead of Shape (covariant return types)
• feat: exported Shape abstract class for consumers to extend

Maintenance

• chore: deprecated AngleUtils in favor of Rad/Deg extensions from units.dart
• chore: removed unused TransformationsMixin dead code
• chore: established angle convention — transforms take degrees, Line angle methods return Rad
• test: comprehensive test suite covering all classes
