Public constructors

public NavGraphNavigator (NavigatorProvider navigatorProvider)

Construct a Navigator capable of routing incoming navigation requests to the proper destination within a NavGraph.

Parameters
`navigatorProvider`	`NavigatorProvider`: NavigatorProvider used to retrieve the correct `Navigator` to navigate to the start destination

Public methods

createDestination

public NavGraph createDestination ()

Creates a new NavGraph associated with this navigator.

Returns
`NavGraph`	a new NavDestination

public NavDestination navigate (NavGraph destination, 
                Bundle args, 
                NavOptions navOptions, 
                Navigator.Extras navigatorExtras)

Navigate to a destination.

Requests navigation to a given destination associated with this navigator in the navigation graph. This method generally should not be called directly; NavController will delegate to it when appropriate.

Parameters
`destination`	`NavGraph`: destination node to navigate to
`args`	`Bundle`: arguments to use for navigation
`navOptions`	`NavOptions`: additional options for navigation
`navigatorExtras`	`Navigator.Extras`: extras unique to your Navigator.

Returns
`NavDestination`	The NavDestination that should be added to the back stack or null if no change was made to the back stack (i.e., in cases of single top operations where the destination is already on top of the back stack).

popBackStack

public boolean popBackStack ()

Attempt to pop this navigator's back stack, performing the appropriate navigation.

Implementations should return true if navigation was successful. Implementations should return false if navigation could not be performed, for example if the navigator's back stack was empty.

Returns
`boolean`	`true` if pop was successful
