AppDimensScope class abstract final

EN: Global resolution scope — the Flutter analog of the KMP metricsScope / Compose LocalDimenMetrics. AppDimensProvider publishes each window snapshot here so num.sdp-style getters resolve through one static read + one multiply (the fast lane).

Every publication fires notifier, so widgets that must track live window changes (resize, rotation, split-screen) can subscribe through AppDimensReactiveBuilder — the analog of Compose readers recomposing on LocalDimenMetrics.current changes.

PT: Escopo global de resolução — o análogo Flutter do metricsScope / LocalDimenMetrics do KMP. O AppDimensProvider publica cada snapshot de janela aqui para que getters como num.sdp resolvam com uma leitura estática e uma multiplicação (a faixa rápida).

Cada publicação dispara notifier, então widgets que precisam acompanhar mudanças ao vivo da janela (resize, rotação, split-screen) podem assinar via AppDimensReactiveBuilder — o análogo dos leitores Compose que recompostam quando LocalDimenMetrics.current muda.

Static Properties

context → AppDimensContextLike?

Currently published window context, or null.

no setter

metrics → DimenMetrics?

Currently published snapshot, or null before any publication.

no setter

metricsOrDefault → DimenMetrics

The effective snapshot: explicit slot, else the engine fallback.

no setter

notifier → MetricsChangeNotifier

Fired once per publication cycle; reactive widgets listen to this.

final

uiModeTypeOrDefault → UiModeType

The effective ui-mode type: published value, else undefined.

no setter

Static Methods

clear() → void

Clears every slot (used by tests).

fireIfChanged(DimenMetrics metrics, UiModeType uiModeType) → void

EN: Fires notifier only when the visible snapshot actually changed. PT: Dispara o notifier apenas quando o snapshot visível mudou de fato.

publish(DimenMetrics metrics) → void

Publishes metrics as the process-wide snapshot (fast-lane slot).

publishContext(AppDimensContextLike context) → void

Publishes the window context used by facilitators and the full engine.

publishUiModeType(UiModeType type) → void

Publishes the detected/forced UiModeType (used by *Mode/*Screen).

withMetrics<T>(DimenMetrics metrics, T body()) → T

Runs body with an explicit metrics scope (save/restore), mirroring DimenCache.withMetrics.
