NavigationStack<T extends RouteTarget> class
A widget that renders a stack of pages based on a NavigationPath.
This is the core widget for imperative navigation. It listens to the path and updates the Navigator with the corresponding pages.
Role in Navigation Flow
NavigationStack is the visual representation of a NavigationPath:
- Listens to path changes via path listeners
- Uses Myers diff algorithm to calculate route changes
- Builds Page objects via the resolver callback
- Updates Flutter's Navigator with the page stack
The widget handles:
- Page creation and disposal
- Guard execution on pop attempts
- Route result completion
- State restoration
