StatefulNavigationShell class

Widget for managing the state of a StatefulShellRoute.

Normally, this widget is not used directly, but is instead created internally by StatefulShellRoute. However, if a custom container for the branch Navigators is required, StatefulNavigationShell can be used in the builder or pageBuilder methods of StatefulShellRoute to facilitate this. The container is created using the provided ShellNavigationContainerBuilder, where the List of Widgets represent the Navigators for each branch.

Example:

builder: (BuildContext context, GoRouterState state,
    StatefulNavigationShell navigationShell) {
  return StatefulNavigationShell(
    shellRouteState: state,
    containerBuilder: (_, __, List<Widget> children) => MyCustomShell(shellState: state, children: children),
  );
}
