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.

isNavigationKey(LogicalKeyboardKey key) → bool

Whether key drives keyboard value changes (arrows, page, home/end).

keyboardStep(double min, double max, int? divisions, {required bool coarse}) → double

Arrow step, or the Space+arrow step when coarse is true.

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

lerp.

pageStep(double step, int? divisions) → double

Larger keyboard step: one division, or 10% of the range when continuous.

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.

stepSize(double min, double max, int? divisions) → double

Single keyboard step: one division, or 1% of the range when continuous.

tickFractions(int? divisions) → List<double>

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

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

Maps a 0..1 fraction back into min..max.

valueFromOffset({required double localPrimary, required double extent, required double min, required double max, required int? divisions, required bool reverse}) → double

Local pointer position → value along the track axis.
