Steering class final

One attempt's steering.

Constructors

Steering(ThemeIntent intent, {bool centred = false})

Properties

baseRange → ({int lo, int span})?

The steered base hue range as (lo tenths, clockwise span tenths), or null when the intent sets no base hue.

no setter

centred → bool

final

hashCode → int

The hash code for this object.

no setter, inherited

intent → ThemeIntent

final

runtimeType → Type

A representation of the runtime type of the object.

Methods

accentHue(Rng r, int index) → int?

The steered operator (index 0) or = (index 1) hue (tenths), drawn from r; null when the intent names no accent colour, or names a harmony (which then places the accents).

baseHue(Rng r) → int?

The steered base hue (tenths), drawn from r; null when the intent sets no base hue. Always draws once when steering hues, so the accent draws keep their place.

brightnessFor(FamilyDefinition def) → ThemeBrightness?

The brightness to use instead of the drawn one, when def can draw it; null keeps the draw.

closestHero(int seed, ThemeFamily family) → ThemeSpec

The deterministic last resort for a steered (seed, family) when every attempt fails: the hero closest to the intent (brightness first, then base hue), preferring the family's own heroes.

nameOr(String generated()) → String

The theme's name: the intent's, else generated.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pickIn(int lo, int span, int u32) → int

A hue in the clockwise range (lo, span) from the 32-bit draw u32 (its middle when centred).

revise(FamilyDefinition def) → FamilyDefinition

def with every role's chroma range narrowed to the intent's chroma level (and the base roles quietened for a neutral first colour).

schemeFor(List<Weighted<HarmonyScheme>> schemes) → HarmonyScheme?

The harmony scheme to use instead of the drawn one, when schemes offers it; null keeps the draw.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
