Rect class
An immutable, 2D, axis-aligned, floating-point rectangle whose coordinates are relative to a given origin.
A Rect can be created with one of its constructors or from an Offset and a
Size using the & operator:
Rect myRect = const Offset(1.0, 2.0) & const Size(3.0, 4.0);
Constructors
- Rect.fromCenter({required Offset center, required double width, required double height})
- Constructs a rectangle from its center point, width, and height.
- Rect.fromCircle({required Offset center, required double radius})
- Construct a rectangle that bounds the given circle.
- Rect.fromLTRB(double left, double top, double right, double bottom)
-
Construct a rectangle from its left, top, right, and bottom edges.
const
- Rect.fromLTWH(double left, double top, double width, double height)
-
Construct a rectangle from its left and top edges, its width, and its
height.
const
- Rect.fromPoints(Offset a, Offset b)
- Construct the smallest rectangle that encloses the given offsets, treating them as vectors from the origin.
