ThreePaneScaffoldValue
Class

@ExperimentalMaterial3AdaptiveApi
class ThreePaneScaffoldValue(
    val primary: PaneAdaptedValue,
    val secondary: PaneAdaptedValue,
    val tertiary: PaneAdaptedValue
)
The adapted value of ThreePaneScaffold. It contains each pane's adapted value.
ThreePaneScaffold will use the adapted values to decide which panes should be displayed
and how they should be displayed. With other input parameters of ThreePaneScaffold fixed,
each possible instance of this class should represent a unique state of ThreePaneScaffold
and developers can compare two ThreePaneScaffoldValue to decide if there is a layout structure
change.
For a Material-opinionated layout, it's suggested to use calculateThreePaneScaffoldValue to
calculate the current scaffold value.
