keepStateInParameters property

bool keepStateInParameters

Indicates if persisting of navigation state in destination parameters is needed.

When it is true, the following is happened on navigation to a destination:

• If DestinationSettings.reset is not set in the requested destination, the current navigation state is saved in the requested destination parameters. Particularly, the currentDestination is saved in the DestinationParameters.upwardParameterName parameter, and current destination of each nested NavigationController is saved in the DestinationParameters.nestedParameterName parameter of the requested destination.
• If DestinationSettings.reset is true, the navigation state is restored from the requested destination parameters.

Implementation

bool get keepStateInParameters =>
    builder.keepStateInParameters == KeepingStateInParameters.always ||
    builder.keepStateInParameters == KeepingStateInParameters.auto && kIsWeb;
