AngleRange class
Represents angle ranges as a circular sector by using an absolute start angle and a relative range angle called extent.
They both define a sector on a circle. All angles are in degrees and are clockwise-oriented. By default, the AngleRange represents the entire circle, the value is in the range of [0, 360]. Values will be corrected during construction using normalization for the start angle and clamping for the extent angle, ensuring a valid range for all possible inputs.

Methods
-
closestInRange(
double angleClockwiseInDegreesFromNorth) → double - Get the angle that is closest to the given one and in range.
-
inRange(
double angleClockwiseInDegreesFromNorth) → bool - Check if a given angle in degrees, clockwise from north is in range or not.
-
max(
) → double - Get the maximum angle defined by the range in degrees, clockwise from north, normalized to [0,360).
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.

operator ==(
Object other) → bool - The equality operator.
Static Methods
-
fromDirectionDegreesClockwise(
double center, double extent) → AngleRange - Constructs an AngleRange from the provided center angle defining the direction and an angular width to extent the range by 50% clockwise and 50% counter-clockwise from its center angle.
-
fromMinMaxDegreesClockwise(
double min, double max) → AngleRange - Constructs an AngleRange from the provided minimum and maximum angles.
