Point(double x, double y, [double? pressure])
const

Properties

direction → double
The angle of this offset as radians clockwise from the positive x-axis, in the range -pi to pi, assuming positive values of the x-axis go to the right and positive values of the y-axis go down.
no setterinherited
distance → double
The magnitude of the offset.
no setterinherited
distanceSquared → double
The square of the magnitude of the offset.
no setterinherited
dx → double
The x component of the offset.
no setterinherited
dy → double
The y component of the offset.
no setterinherited
hashCode → int
Returns a hash of the x and y values. This matches the hashcode of an Offset with those same values.
no setterinherited
isFinite → bool
Whether both components are finite (neither infinite nor NaN).
no setterinherited
isInfinite → bool
Returns true if either component is double.infinity, and false if both are finite (or negative infinity, or NaN).
no setterinherited
p → double
Deprecated non-nullable pressure value.
no setterinherited
pressure → double?
The pressure of the point, between 0 and 1, or null if the pressure is unknown.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
x → double
Identical to dx
finalinherited
y → double
Identical to dy

inherited
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 ==(Object other) → bool
Compares this PointVector to an Offset or PointVector other for equality.
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.
inherited
operator unary-() → PointVector
Negates the vector.
inherited
operator ~/(double operand) → Offset
