Rect class
An immutable, 2D, axisaligned, floatingpoint 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.
Properties

The offset to the center of the bottom edge of this rectangle.
readonly
 bottomLeft → Offset

The offset to the intersection of the bottom and left edges of this rectangle.

bottom edges of this rectangle.
readonly
 centerLeft → Offset

The offset to the center of the left edge of this rectangle.
readonly
 centerRight → Offset

readonlyoverride
 hasNaN → bool

Whether any of the dimensions are
NaN
.readonly  height → double

 isFinite → bool

Whether all coordinates of this rectangle are finite.
readonly
 isInfinite → bool

Whether any of the coordinates of this rectangle are equal to positive infinity.
readonly
 left → double

rectangle.
readonly
 right → double

The offset of the right edge of this rectangle from the x axis.
final
 runtimeType → Type

A representation of the runtime type of the object.
readonlyinherited
 shortestSide → double

The lesser of the magnitudes of the width and the height of this
rectangle.
readonly
 size → Size

The distance between the upperleft corner and the lowerright corner of
this rectangle.
readonly
 top → double

The offset of the top edge of this rectangle from the y axis.
final
 topCenter → Offset

The offset to the center of the top edge of this rectangle.
readonly
 topLeft → Offset

The offset to the intersection of the top and left edges of this rectangle.
readonly
 topRight → Offset

The offset to the intersection of the top and right edges of this rectangle.
readonly
 width → double

The distance between the left and right edges of this rectangle.

Methods

contains(
Offset offset) → bool  Whether the point specified by the given offset (which is assumed to be relative to the origin) lies between the left and right and the top and bottom edges of this rectangle.

deflate(
double delta) → Rect  Returns a new rectangle with edges moved inwards by the given delta.

expandToInclude(
Rect other) → Rect  Returns a new rectangle which is the bounding box containing this rectangle and the given rectangle.

inflate(
double delta) → Rect  Returns a new rectangle with edges moved outwards by the given delta.

intersect(
Rect other) → Rect  Returns a new rectangle that is the intersection of the given rectangle and this rectangle. The two rectangles must overlap for this to be meaningful. If the two rectangles do not overlap, then the resulting Rect will have a negative width or height.

noSuchMethod(
Invocation invocation) → dynamic 
Invoked when a nonexistent method or property is accessed.
inherited

overlaps(
Rect other) → bool 
Whether
other
has a nonzero area of overlap with this rectangle. 
shift(
Offset offset) → Rect  Returns a new rectangle translated by the given offset.

toString(
) → String 
A string representation of this object.
override

translate(
double translateX, double translateY) → Rect  Returns a new rectangle with translateX added to the x components and translateY added to the y components.
Operators

operator ==(
Object other) → bool 
The equality operator.
