MutableRectangle<T extends num> class
A class for representing two-dimensional axis-aligned rectangles with mutable properties.
Legacy: New usages of MutableRectangle are discouraged.
- If you are using the
MutableRectangle
class withdart:html
, we recommend migrating topackage: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 fromdart:ui
.
- Implemented types
- Rectangle<
T>
- Rectangle<
Constructors
- MutableRectangle.new(T left, T top, T width, T height)
- Create a mutable rectangle spanned by
(left, top)
and(left+width, top+height)
. - MutableRectangle.fromPoints(Point<
T> a, Point<T> b) - Create a mutable rectangle spanned by the points
a
andb

Methods
- boundingBox(
Rectangle< T> other) → Rectangle<T> - Returns a new rectangle which completely contains
this
andother
.inherited - containsPoint(
Point< num> another) → bool - Tests whether
another
is inside or along the edges ofthis
.inherited - containsRectangle(
Rectangle< num> another) → bool - Tests whether
this
entirely containsanother
.inherited - intersection(
Rectangle< T> other) → Rectangle<T> ? - Computes the intersection of
this
andother
.inherited - intersects(
Rectangle< num> other) → bool - Returns true if
this
intersectsother
.inherited - noSuchMethod(
Invocation invocation) → dynamic - Invoked when a nonexistent method or property is accessed.inherited
- toString(
) → String - A string representation of this object.inherited
Operators
- operator ==(
Object other) → bool - The equality operator.inherited
