ModalNavigationDrawer

Component in Tv Material Compose

Navigation drawers provide ergonomic access to destinations in an app. Modal navigation drawers are good for infrequent, but more focused, switching to different destinations.

It displays content associated with the closed state when the drawer is not in focus and displays content associated with the open state when the drawer or its contents are focused on. Modal navigation drawers are elevated above most of the app’s UI and don’t affect the screen’s layout grid.

    drawerContent: @Composable NavigationDrawerScope.(DrawerValue) -> Unit,
    modifier: Modifier = Modifier,
    drawerState: DrawerState = rememberDrawerState(DrawerValue.Closed),
    scrimBrush: Brush = SolidColor(LocalColorScheme.current.scrim.copy(alpha = 0.5f)),
    content: @Composable () -> Unit
)

Parameters

name	description
drawerContent	Content that needs to be displayed on the drawer based on whether the drawer is [DrawerValue.Open] or [DrawerValue.Closed]. Drawer-entries can be animated when the drawer moves from Closed to Open state and vice-versa. For, e.g., the entry could show only an icon in the Closed state and slide in text to form (icon + text) when in the Open state.To limit the width of the drawer in the open or closed state, wrap the content in a box with therequired width.
modifier	the [Modifier] to be applied to this drawer
drawerState	state of the drawer
scrimBrush	brush to paint the scrim that obscures content when the drawer is open
content	content of the rest of the UI. The content extends to the edge of the container under the modal navigation drawer. Focusable content that is not part of the background must have start-padding sufficient to prevent it from being drawn under the drawer in the Closed state.
