CupertinoTabView class

A single tab view with its own Navigator state and history.

A typical tab view used as the content of each tab in a CupertinoTabScaffold where multiple tabs with parallel navigation states and history can co-exist.

CupertinoTabView configures the top-level Navigator to search for routes in the following order:

  1. For the / route, the builder property, if non-null, is used.

  2. Otherwise, the routes table is used, if it has an entry for the route, including / if builder is not specified.

  3. Otherwise, onGenerateRoute is called, if provided. It should return a non-null value for any valid route not handled by builder and routes.

  4. Finally if all else fails onUnknownRoute is called.

These navigation properties are not shared with any sibling CupertinoTabView nor any ancestor or descendant Navigator instances.

To push a route above this CupertinoTabView instead of inside it (such as when showing a dialog on top of all tabs), use Navigator.of(rootNavigator: true).
