Properties

fill → Color

Key background.

final

hashCode → int

The hash code for this object.

no setter, override

label → Color

Label colour (≥ 4.5:1 against fill).

final

labelWeight → FontWeight

Label weight. Operators and = use a heavier weight than digits so they differ by more than colour (spec §5.4).

final

outline → Color?

Optional key outline (high-contrast themes: ≥ 3:1 against the background, so the key's extent is visible); null for none.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

labelWeightFor({required bool boldText}) → FontWeight

The label weight under the platform's Bold Text setting: three steps heavier (w400 → w700, w600 → w900), so roles keep their weight order instead of all becoming bold.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
