A complete theme (spec §5.1). Immutable; == compares every field; hashCode is stableHash, identical on every run and platform.

Parses source produced by toJsonString.

factory

Properties

accessible → bool

Generated under the Accessible lock (labels ≥ 7:1, rims ≥ 3:1).

final

background → BackgroundSpec

final

brightness → ThemeBrightness

final

effects → EffectsSpec

final

engineVersion → int

Generator version that produced this theme (share codes carry it).

final

family → ThemeFamily

final

hashCode → int

The hash code for this object.

no setter, override

heroId → int?

Hero id when variant is ThemeVariant.hero.

final

intent → ThemeIntent?

The steering intent of a ThemeVariant.steered theme (without its families and name: the name is name); null otherwise. Serialised only when set, like seedHueTenths.

final

intentCentred → bool

Whether a steered theme was generated centred (the first theme of a steered feed: every narrowed choice at the middle of its range).

final

isDark → bool

Whether this is a dark theme.

no setter

keyShape → KeyShapeSpec

final

keyStyle → KeyStyleSpec

final

motion → MotionSpec

final

name → String

Generated name, e.g. "Mango Midnight".

final

nonColourOperatorCue → OperatorCue

The non-colour cue the family supplies for operator / = keys, if the guardrail relies on it (spec §5.4).

final

palette → Palette

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

seed → int

32-bit unsigned seed.

final

seedHueTenths → int?

The base hue (tenths of a degree) that replaced the palette draw, for the ThemeVariant.wallpaper variant ("Match my wallpaper"); null otherwise. Serialised only when set, so every other theme's canonical JSON and stable hash are unchanged.

final

sound → SoundPackId

Default sound pack (a user-pinned pack overrides it at runtime and is not part of the theme).

final

stableHash → int

FNV-1a-32 over the UTF-8 bytes of toJsonString: identical on every run and platform (unlike Object.hash, which is seeded per process).

no setter

type → TypeSpec

final

variant → ThemeVariant

final

Methods

copyWith({int? seed, ThemeFamily? family, int? engineVersion, ThemeVariant? variant, int? heroId, int? seedHueTenths, ThemeIntent? intent, bool? intentCentred, ThemeBrightness? brightness, bool? accessible, Palette? palette, KeyShapeSpec? keyShape, KeyStyleSpec? keyStyle, TypeSpec? type, BackgroundSpec? background, MotionSpec? motion, EffectsSpec? effects, SoundPackId? sound, String? name, OperatorCue? nonColourOperatorCue}) → ThemeSpec

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, Object?>

Canonical JSON (fixed key order, colours as aarrggbb).

toJsonString() → String

toJson encoded as a compact string (byte-identical everywhere).

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.

override

Constants

jsonFormat → const int

Version of the JSON layout (not the generator; see engineVersion).
