Size class
Holds a 2D floating-point size.
You can think of this as an Offset from the origin.

Constructors
- Size(double width, double height)
-
Creates a Size with the given
width
andheight
.const - Size.copy(Size source)
- Creates an instance of Size that has the same values as another.
- Size.fromHeight(double height)
-
Creates a Size with the given
height
and an infinite width.const - Size.fromRadius(double radius)
-
Creates a square Size whose width and height are twice the given
dimension. [...]
const
- Size.fromWidth(double width)
-
Creates a Size with the given
width
and an infinite height.const - Size.square(double dimension)
-
Creates a square Size whose width and height are the given dimension. [...]

Properties
- flipped → Size
-
A Size with the width and height swapped.
read-only
- hashCode → int
-
The hash code for this object. [...]
read-only, override
- height → double
-
The vertical extent of this size.
read-only
- isEmpty → bool
-
Whether this size encloses a non-zero area. [...]
read-only
- longestSide → double
-
The greater of the magnitudes of the width and the height.
read-only
- shortestSide → double
-
The lesser of the magnitudes of the width and the height.
read-only
- width → double
-
The horizontal extent of this size.
read-only
- isFinite → bool
-
Whether both components are finite (neither infinite nor NaN). [...]
read-only, inherited
- isInfinite → bool
-
Returns true if either component is double.infinity, and false if both
are finite (or negative infinity, or NaN). [...]

Methods
-
bottomCenter(
Offset origin) → Offset - The offset to the center of the bottom edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
bottomLeft(
Offset origin) → Offset - The offset to the intersection of the bottom and left edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
bottomRight(
Offset origin) → Offset - The offset to the intersection of the bottom and right edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
center(
Offset origin) → Offset - The offset to the point halfway between the left and right and the top and bottom edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
centerLeft(
Offset origin) → Offset - The offset to the center of the left edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
centerRight(
Offset origin) → Offset - The offset to the center of the right edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
contains(
Offset offset) → bool - Whether the point specified by the given offset (which is assumed to be relative to the top left of the size) lies between the left and right and the top and bottom edges of a rectangle of this size. [...]
-
topCenter(
Offset origin) → Offset - The offset to the center of the top edge of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
topLeft(
Offset origin) → Offset - The offset to the intersection of the top and left edges of the rectangle described by the given Offset (which is interpreted as the top-left corner) and this Size. [...]
-
topRight(
Offset origin) → Offset - The offset to the intersection of the top and right edges of the rectangle described by the given offset (which is interpreted as the top-left corner) and this size. [...]
-
toString(
) → String -
Returns a string representation of this object.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed. [...]

Operators
-
operator %(
double operand) → Size - Modulo (remainder) operator. [...]
-
operator *(
double operand) → Size - Multiplication operator. [...]
-
operator +(
Offset other) → Size - Binary addition operator for adding an Offset to a Size. [...]
-
operator -(
OffsetBase other) → OffsetBase - Binary subtraction operator for Size. [...]
-
operator /(
double operand) → Size - Division operator. [...]
-
operator ==(
dynamic other) → bool -
Compares two Sizes for equality.
override
-
operator ~/(
double operand) → Size - Integer (truncating) division operator. [...]
-
operator <(
OffsetBase other) → bool -
Less-than operator. Compares an Offset or Size to another Offset or
Size, and returns true if both the horizontal and vertical values of the
left-hand-side operand are smaller than the horizontal and vertical values
of the right-hand-side operand respectively. Returns false otherwise. [...]
inherited
-
operator <=(
OffsetBase other) → bool -
Less-than-or-equal-to operator. Compares an Offset or Size to another
Offset or Size, and returns true if both the horizontal and vertical
values of the left-hand-side operand are smaller than or equal to the
horizontal and vertical values of the right-hand-side operand
respectively. Returns false otherwise. [...]
inherited
-
operator >(
OffsetBase other) → bool -
Greater-than operator. Compares an Offset or Size to another Offset
or Size, and returns true if both the horizontal and vertical values of
the left-hand-side operand are bigger than the horizontal and vertical
values of the right-hand-side operand respectively. Returns false
otherwise. [...]
inherited
-
operator >=(
OffsetBase other) → bool -
Greater-than-or-equal-to operator. Compares an Offset or Size to
another Offset or Size, and returns true if both the horizontal and
vertical values of the left-hand-side operand are bigger than or equal to
the horizontal and vertical values of the right-hand-side operand
respectively. Returns false otherwise. [...]
