routes
I programmed a simple app to show you how to navigate to a new screen by creating a new route and pushing it to the Navigator.
To work with named routes, I used the Navigator.pushNamed() function.
Getting Started
First, create two screens to work with. The first screen contains a button that navigates to the second screen. The second screen contains a button that navigates back to the first.
a) Navigate to Page404 without printing the route
onUnknownRoute: (RouteSettings settings) =>
MaterialPageRoute(builder: (context) => Page404()),
b) Navigate to Page404 printing the route not founded
onUnknownRoute: (RouteSettings settings) {
print('Not found route: ${settings.name}');
return MaterialPageRoute(builder: (context) {
return Page404();
});
}
