Parameters
navigator: ThreePaneScaffoldNavigator<T>

rememberListDetailPaneScaffoldNavigator

Cmn 
@ExperimentalMaterial3AdaptiveApi
@Composable
fun rememberListDetailPaneScaffoldNavigator(
    scaffoldDirective: PaneScaffoldDirective = calculatePaneScaffoldDirective(currentWindowAdaptiveInfo()),
    adaptStrategies: ThreePaneScaffoldAdaptStrategies = ListDetailPaneScaffoldDefaults.adaptStrategies(),
    isDestinationHistoryAware: Boolean = true
): ThreePaneScaffoldNavigator<Any>

Returns a remembered default implementation of ThreePaneScaffoldNavigator for ListDetailPaneScaffold, which will be updated automatically when the input values change. The default navigator is supposed to be used independently from any navigation frameworks and handles the navigation purely inside the ListDetailPaneScaffold.

Parameters
scaffoldDirective: PaneScaffoldDirective = calculatePaneScaffoldDirective(currentWindowAdaptiveInfo())

the current layout directives to follow. The default value will be calculated with calculatePaneScaffoldDirective using WindowAdaptiveInfo retrieved from the current context.
adaptStrategies: ThreePaneScaffoldAdaptStrategies = ListDetailPaneScaffoldDefaults.adaptStrategies()

adaptation strategies of each pane.
isDestinationHistoryAware: Boolean = true

true if the scaffold value calculation should be aware of the full destination history, instead of just the current destination. See calculateThreePaneScaffoldValue for more relevant details.

    initialDestinationHistory: List<ThreePaneScaffoldDestinationItem<T>> = DefaultListDetailPaneHistory
): ThreePaneScaffoldNavigator<T>

Returns a remembered default implementation of ThreePaneScaffoldNavigator for ListDetailPaneScaffold, which will be updated automatically when the input values change. The default navigator is supposed to be used independently from any navigation frameworks and handles the navigation purely inside the ListDetailPaneScaffold.

Parameters
<T : Any?>

the type representing the content key/id for a navigation destination. This type must be storable in a Bundle. Used to customize navigation behavior (for example, BackNavigationBehavior). If this customization is unneeded, you can pass Any.
scaffoldDirective: PaneScaffoldDirective = calculatePaneScaffoldDirective(currentWindowAdaptiveInfo())

the current layout directives to follow. The default value will be calculated with calculatePaneScaffoldDirective using WindowAdaptiveInfo retrieved from the current context.
adaptStrategies: ThreePaneScaffoldAdaptStrategies = ListDetailPaneScaffoldDefaults.adaptStrategies()

adaptation strategies of each pane.
isDestinationHistoryAware: Boolean = true

true if the scaffold value calculation should be aware of the full destination history, instead of just the current destination. See calculateThreePaneScaffoldValue for more relevant details.
initialDestinationHistory: List<ThreePaneScaffoldDestinationItem<T>> = DefaultListDetailPaneHistory

the initial pane destination history of the scaffold, by default it will be just the list pane.
