public val LocalAmbientModeManager: ProvidableCompositionLocal<AmbientModeManager?>A androidx.compose.runtime.CompositionLocal that provides the current AmbientModeManager interface.
This local is the primary way for any composable in the hierarchy to access the manager responsible for tracking the ambient (low-power) mode state.
Composables read the manager using LocalAmbientModeManager.current and subscribe to changes via the AmbientModeManager.currentAmbientMode property.
If no AmbientModeManager is explicitly provided higher up the tree (e.g., via rememberAmbientModeManager), this local returns null.
