OffsetPoint class - signature library

Constructors

OffsetPoint.new({required double dx, required double dy, required int timestamp, double? pressure}): Creates an OffsetPoint with the given coordinates, timestamp, and optional pressure.
const
OffsetPoint.from(Offset offset, {double? pressure}): Creates an OffsetPoint from a standard Offset with the current timestamp and optional pressure.
factory
OffsetPoint.fromMap(Map<String, dynamic> data): Creates an OffsetPoint from a map of data, typically used for deserialization.

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: The hash code for this object.
no setteroverride
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
pressure → double?: The pressure value at this point, if available.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
timestamp → int: Timestamp of this point. Used to determine velocity to other points.
final

Methods

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
scale(double scaleX, double scaleY) → OffsetPoint: Returns a new offset with the x component scaled by scaleX and the y component scaled by scaleY.
override
toMap() → Map<String, dynamic>: Converts this OffsetPoint to a map of data, typically used for serialization.
toString() → String: A string representation of this object.
inherited
translate(double translateX, double translateY) → OffsetPoint: Returns a new offset with translateX added to the x component and translateY added to the y component.
override
velocityFrom(OffsetPoint other) → double: Calculates the velocity between this point and a other (previous) point. Returns 0.0 if timestamps are the same to avoid division by zero.

Operators

operator %(double operand) → Offset: Modulo (remainder) operator.
inherited
operator &(Size other) → Rect: Rectangle constructor operator.
inherited
operator *(double operand) → Offset: Multiplication operator.
inherited
operator +(Offset other) → Offset: Binary addition operator.
inherited
operator -(Offset other) → Offset: Binary subtraction operator.
inherited
operator /(double operand) → Offset: Division operator.
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 two Offsets for equality.
override
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-() → Offset: Unary negation operator.
inherited
operator ~/(double operand) → Offset: Integer (truncating) division operator.
