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

 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. [...]

 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.
readonly
 hashCode → int

readonly
 height → double

The vertical extent of this size.
readonly
 isEmpty → bool

Whether this size encloses a nonzero area. [...]
readonly
 longestSide → double

The greater of the magnitudes of the width and the height.
readonly
 shortestSide → double

The lesser of the magnitudes of the width and the height.
readonly
 width → double

The horizontal extent of this size.
readonly
 isFinite → bool

Whether both components are finite (neither infinite nor NaN). [...]
readonly, 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 topleft 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 topleft 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 topleft 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 topleft 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 topleft 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 topleft 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 topleft 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 topleft 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 topleft corner) and this size. [...]

toString(
) → String 
noSuchMethod(
Invocation invocation) → dynamic 
Invoked when a nonexistent 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.

operator ~/(
double operand) → Size  Integer (truncating) division operator. [...]

operator <(
OffsetBase other) → bool 
Lessthan operator. Compares an Offset or Size to another Offset or
Size, and returns true if both the horizontal and vertical values of the
lefthandside operand are smaller than the horizontal and vertical values
of the righthandside operand respectively. Returns false otherwise. [...]
inherited

operator <=(
OffsetBase other) → bool 
Lessthanorequalto operator. Compares an Offset or Size to another
Offset or Size, and returns true if both the horizontal and vertical
values of the lefthandside operand are smaller than or equal to the
horizontal and vertical values of the righthandside operand
respectively. Returns false otherwise. [...]
inherited

operator >(
OffsetBase other) → bool 
Greaterthan operator. Compares an Offset or Size to another Offset
or Size, and returns true if both the horizontal and vertical values of
the lefthandside operand are bigger than the horizontal and vertical
values of the righthandside operand respectively. Returns false
otherwise. [...]
inherited

operator >=(
OffsetBase other) → bool 
Greaterthanorequalto operator. Compares an Offset or Size to
another Offset or Size, and returns true if both the horizontal and
vertical values of the lefthandside operand are bigger than or equal to
the horizontal and vertical values of the righthandside operand
respectively. Returns false otherwise. [...]
