Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

angleDx(double degrees, double radius) → double

For a given angle and radius, finds the X portion of the offset. @param {number} degrees Angle in degrees (zero points in +X direction). @param {number} radius Radius. @return {number} The x-distance for the angle and radius.

angleDy(double degrees, double radius) → double

For a given angle and radius, finds the Y portion of the offset. @param {number} degrees Angle in degrees (zero points in +X direction). @param {number} radius Radius. @return {number} The y-distance for the angle and radius.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

angle(double x1, double y1, double x2, double y2) → double

Computes the angle between two points (x1,y1) and (x2,y2). Angle zero points in the +X direction, 90 degrees points in the +Y direction (down) and from there we grow clockwise towards 360 degrees. @param {number} x1 x of first point. @param {number} y1 y of first point. @param {number} x2 x of second point. @param {number} y2 y of second point. @return {number} Standardized angle in degrees of the vector from x1,y1 to x2,y2.

atan2(num a, num b) → double

atan2

cos(num radians) → double

cos

degreesToRadians(double angleDegrees) → double

Converts degrees to radians. @param {number} angleDegrees Angle in degrees. @return {number} Angle in radians.

log10(num value) → double

log10

max<T extends num>(T a, T b) → T

Return highest of two values

min<T extends num>(T a, T b) → T

Return lowest of two values

modulo(double a, double b) → double

The % operator in JavaScript returns the remainder of a / b, but differs from some other languages in that the result will have the same sign as the dividend. For example, -1 % 8 == -1, whereas in some other languages (such as Python) the result would be 7. This function emulates the more correct modulo behavior, which is useful for certain applications such as calculating an offset index in a circular list.

pow<T extends num>(num x, num exponent) → num

pow

radiansToDegrees(double angleRadians) → double

Converts radians to degrees. @param {number} angleRadians Angle in radians. @return {number} Angle in degrees.

sin(num radians) → double

sin

sqrt(num x) → double

sqrt

standardAngle(double angle) → double

Normalizes an angle to be in range [0-360). Angles outside this range will be normalized to be the equivalent angle with that range. @param {number} angle Angle in degrees. @return {number} Standardized angle.

Constants

DOUBLE_MAX_VALUE → const double

DOUBLE_MIN_VALUE → const double

INT_MAX_VALUE → const int

A constant holding the maximum value an int can have, 231-1.

INT_MIN_VALUE → const int

PI → const double

The PI constant.
