Static Methods

clampRangeEnd(double start, double end, double max) → double

clampRangeEnd.

clampRangeStart(double start, double end, double min) → double

clampRangeStart.

fraction(double value, double min, double max) → double

0..1 fraction of value within min..max.

lerp(double a, double b, double t) → double

lerp.

snap(double value, double min, double max, int? divisions) → double

Snaps value to the nearest division step.

snapFraction(double fraction, List<double> ticks) → double

Closest tick fraction to fraction, or fraction when there are none.

tickFractions(int? divisions) → List<double>

Tick fractions when divisions > 0 (Compose steps → steps + 2 marks).

valueFromFraction(double fraction, double min, double max) → double
