Rectangle<T extends num> class

A class for representing two-dimensional rectangles whose properties are immutable.

Legacy: New usages of Rectangle are discouraged.

  • If you are using the Rectangle class with dart:html, we recommend migrating to package:web. To learn how and why to migrate, check out the migration guide.
  • If you want to store the boundaries of a rectangle in some coordinate system, consider using a record. Depending on how you will use it, this could look like var boundaries = (mixX: x1, maxX: x2, minY: y1, maxY: y2).
  • If you need to perform intersection calculations or containment checks, consider using a dedicated library, such as package:vector_math.
  • If you are developing a Flutter application or package, consider using the Rect type from dart:ui.
