RouteNode<TArgs> class abstract

Base class for all nodes in the safe routing tree.

A RouteNode represents a single element in the route hierarchy. It can be either:

• a SafeRoute (a leaf node with a page builder)
• a SafeNestedRoute (a container grouping other routes)

Each node has:

• name → the relative path (e.g. "/settings")
• _parent → reference to its parent node

Together, they allow constructing a full path by walking up the tree.

Example:

final profileRoute = SafeRoute<String, void>(
  name: '/profile',
  builder: (_, username) => ProfilePage(username: username),
);

final accountRoutes = SafeNestedRoute(
  name: '/account',
  routes: [profileRoute],
);

// profileRoute.fullPath == "/account/profile"
