Properties

centerValue → Angle
The value at the center of the range.
no setterinherited
delta → Angle
The change in value from start to end, which may be negative.
no setteroverride
endAngle → Angle
The ending angle in the range.
no setter
hashCode → int
Two equal quantity ranges will have the same hash code.
no setterinherited
isAnticlockwise → bool
True if the range represents a anticlockwise direction.
no setter
isClockwise → bool
True if the range represents a clockwise direction.
no setter
isCounterclockwise → bool
True if the range represents a counterclockwise direction.
no setter
maxValue → Angle
The maximum value in this range.
no setterinherited

ranges360 → List<AngleRange>
Returns the equivalent range(s) projected onto the 0-360 degree circle.
no setter
revolutions → int
The number of full revolutions encompassed by the range.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
span → Angle
The magnitude of the range. This value is always positive (or zero). Get delta for the signed version of the range.

Methods

angleClosestTo(Angle angle, [bool strict = false]) → Angle
Find the angle within this range closest to the specified angle.
contains(Angle quantity, [bool inclusive = true, double epsilon = 1.0e-10]) → bool
True if this range contains quantity, with a tolerance, epsilon, of rounding errors of 1.0e-10 and inclusive of the endpoints by default.
inherited
contains360(Angle angle, [bool inclusive = true, double epsilon = 1.0e-10]) → bool
True if this range, projected onto the 0-360 degree circle contains angle when it also is projected onto the 0-360 circle.
deriveRange({double? rotate, double? scale, bool? reverse}) → AngleRange
Derive a AngleRange from this one by applying one or more transforms.
encompasses(QuantityRange<Angle> range2) → bool
True only if this range completely encompasses range2.
inherited
isTiny({Angle? epsilon}) → bool
A range is considered tiny if its width is less than or equal to epsilon, which is 0.001 degree by default.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
overlaps(QuantityRange<Angle> range2) → bool
Returns true if this range overlaps range2 (exclusive of the endpoints).
inherited
overlaps360(AngleRange range2) → bool
Returns true if this angle range overlaps range2's angle range (exclusive of the endpoints).
toString() → String
Returns a String representation of this range in the form '
inherited

Operators

operator ==(Object obj) → bool
Two quantity ranges are considered equal only if their endpoints are exactly equal.
