Base class for Size and Offset, which are both ways to describe a distance as a two-dimensional axis-aligned vector.
Constructors
- OffsetBase(double _dx, double _dy)
-
Abstract const constructor. This constructor enables subclasses to provide const constructors so that they can be used in const expressions.

Properties
- hashCode → int
-
read-only
- isInfinite → bool
-
Returns true if either dimension is
double.INFINITY, and false if both are finite (or negative infinity, or NaN).read-only - runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
Operators
-
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.
-
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.
-
operator ==(
other) → bool -
Equality operator. Compares an Offset or Size to another Offset or Size, and returns true if the horizontal and vertical values of the left-hand-side operand are equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.
-
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.
-
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.
Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited -
toString(
) → String -
Returns a string representation of this object.
