gorouter_with_stored_tabs

An example of implementing the classic "Stateful Tabs" or "Nested Tabs" style navigation with GoRouter.

• Pages within each tab should remember their state
• When changing tabs, the tabs should remember what page they were showing last
• When pressing a selected tab, it should pop all routes and return to the root tab

Classically this is achieved by having multiple child Navigators that internally hold their own state by being rendered offstage.

This takes a different approach:

• Uses the PageStorage API to allow each route to restore state and remember scroll positions etc.
• Uses the users location history to determine which view we should show when a tab is pressed.
