String, dynamic> map) -
Creates a point from a Map with 'x' and 'y' keys.
factory
- Point.fromPolar(double radius, double angle)
-
Creates a point from polar coordinates.

Properties
- angle → double
-
Returns the angle of this point relative to the origin.
no setter
- hashCode → int
-
The hash code for this object.
no setteroverride
- hasNaN → bool
-
Returns true if this point has NaN values.
no setter
- isFinite → bool
-
Returns true if this point is finite.
no setter
- magnitude → double
-
Returns the magnitude (length) of this point as a vector.
no setter
- normalized → Point
-
Returns a normalized version of this point (unit vector).
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- squaredMagnitude → double
-
Returns the squared magnitude of this point as a vector.
no setter

final
- y → double
-
The y coordinate.

Methods
-
clamp(
{double? minX, double? maxX, double? minY, double? maxY}) → Point - Clamps this point to the given bounds.
-
copyWith(
{double? x, double? y}) → Point - Returns a copy with updated values.
-
cross(
Point other) → double - Returns the cross product (z-component) with another point.
-
distanceTo(
Point other) → double - Returns the Euclidean distance to another point.
-
dot(
Point other) → double - Returns the dot product with another point.
-
lerp(
Point other, double t) → Point - Linearly interpolates between this point and another.
-
manhattanDistanceTo(
Point other) → double - Returns the Manhattan distance to another point.
-
midpointTo(
Point other) → Point - Returns the midpoint between this point and another.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
rotate(
double angle) → Point - Returns a rotated version of this point around the origin.
-
rotateAround(
Point center, double angle) → Point - Returns a rotated version around a center point.
-
squaredDistanceTo(
Point other) → double - Returns the squared distance to another point. More efficient than distanceTo when comparing distances.
-
toList(
) → List< double> -
Converts to a List
x, y. -
toMap(
) → Map< String, double> - Converts to a Map.
-
toString(
) → String -
A string representation of this object.

Operators
-
operator *(
double scalar) → Point - Multiplies the point by a scalar.
-
operator +(
Point other) → Point - Adds two points.
-
operator -(
Point other) → Point - Subtracts two points.
-
operator /(
double scalar) → Point - Divides the point by a scalar.
-
operator ==(
Object other) → bool -
The equality operator.
override
-
operator unary-(
) → Point - Negates the point.
