Navigation
Navigation is essential for building engaging and intuitive Flutter apps, enabling users to seamlessly move between different screens and sections.
Using the Navigator
The Navigator class in Flutter manages a stack of Route objects and allows for navigation between different screens or routes within an app. To navigate to a new screen, access the Navigator
through the route's BuildContext
and utilize imperative methods like push()
or pop()
:
onPressed: () {
Navigator.of(context).push(
MaterialPageRoute(
builder: (context) => const SongScreen(song: song),
),
);
},
child: Text(song.name),
Because the Navigator maintains a stack of Route objects representing the navigation history, the push()
method requires a Route object. The MaterialPageRoute class, a subclass of Route, specifies transition animations, particularly for Material Design.
Using named routes
Named routes offer a way to define and navigate to specific screens using unique identifiers rather than directly referencing the widget class. While useful for simpler navigation (Navigator
) and deep linking requirements (MaterialApp.routes).
Routes specified here are called named routes. For a complete example:
routes: {
'/': (context) => HomeScreen(),
'/details': (context) => DetailScreen(),
},
Using the Router
For advanced navigation needs, like web apps with direct links or apps with multiple Navigator
widgets, consider using a routing package like go_router. Configure it through MaterialApp's router constructor:
MaterialApp.router(
routerConfig: GoRouter( // Configuration details
)
);
Using Router and Navigator together
The Router
and Navigator
complement each other. Navigate using the Router
API or directly through the Navigator. Routes from the Router are page-backed, while those from Navigator.push() are pageless. Removing a page-backed route also removes subsequent pageless routes until the next page-backed one.

Adding Tabs to Your App
Adding Tabs to Your App
Tabs are a familiar feature in apps adhering to Material Design principles. Flutter simplifies tab layout creation through its material library.
Here's how to create a tabbed layout:
Set up a
TabController
.Define the tabs.
Populate each tab with content.
Create a TabController
To enable tab functionality, synchronize the selected tab with its corresponding content using a TabController. You can create a TabController
manually or opt for the easier route by utilizing the DefaultTabController widget, which automatically generates and shares a TabController
with all descendant widgets.
return MaterialApp(
home: DefaultTabController(
length: 3,
child: Scaffold(),
),
);
Create the tabs
To display content when a tab is selected, utilize the TabBar widget. In this scenario, construct a TabBar with three Tab widgets and nest it within an AppBar.
return MaterialApp(
home: DefaultTabController(
length: 3,
child: Scaffold(
appBar: AppBar(
bottom: const TabBar(
tabs: [
Tab(icon: Icon(Icons.directions_car)),
Tab(icon: Icon(Icons.directions_transit)),
Tab(icon: Icon(Icons.directions_bike)),
],
),
),
),
),
);
By default, the TabBar searches for the nearest DefaultTabController in the widget tree. If you're manually creating a TabController, ensure to pass it to the TabBar.
Create content for each tab
To display content corresponding to each tab selection, incorporate the TabBarView widget.
body: const TabBarView(
children: [
Icon(Icons.directions_car),
Icon(Icons.directions_transit),
Icon(Icons.directions_bike),
],
),

In Flutter, routes represent screens or pages in an app. Using the Navigator widget, you can navigate between routes. This recipe focuses on navigating between two routes using Navigator.push() to move to the second route and Navigator.pop() to return to the first route.
Create two routes
Let's set up the visual structure by creating two routes. Each route will consist of a single button. Tapping the button on the first route will navigate to the second route, and tapping the button on the second route will return to the first route.
class FirstRoute extends StatelessWidget {
const FirstRoute({super.key});
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('First Route'),
),
body: Center(
child: ElevatedButton(
child: const Text('Open route'),
onPressed: () {
// Navigate to second route when tapped.
},
),
),
);
}
}
class SecondRoute extends StatelessWidget {
const SecondRoute({super.key});
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Second Route'),
),
body: Center(
child: ElevatedButton(
onPressed: () {
// Navigate back to first route when tapped.
},
child: const Text('Go back!'),
),
),
);
}
}
Navigate to the second route using Navigator.push()
To transition to a new route, utilize the Navigator.push() method. This method adds a Route to the stack of routes managed by the Navigator. You can create your own Route or opt for a MaterialPageRoute, which facilitates seamless transitions to the new route with platform-specific animations.
In the build()
method of the FirstRoute
widget, update the onPressed()
callback accordingly.
// Within the `FirstRoute` widget
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => const SecondRoute()),
);
}
Return to the first route using Navigator.pop()
To return to the first route from the second, use Navigator.pop(). This method removes the current route from the stack. Update the onPressed()
callback in the SecondRoute
widget to achieve this.
// Within the SecondRoute widget
onPressed: () {
Navigator.pop(context);
}
Navigation with CupertinoPageRoute
In Flutter, besides Material components, you also have access to Cupertino (iOS-style) widgets. You can use CupertinoPageRoute for iOS-style transitions between screens. Replace MaterialApp
with CupertinoApp
, Scaffold
with CupertinoPageScaffold
, and ElevatedButton
with CupertinoButton
to align with iOS design.

Sending Data to a New Screen
Sending Data to a New Screen
Let's explore how to navigate to a new screen while passing data to it. Consider a scenario where you want to pass information about a tapped item.
Here's how you can achieve this:
Define a todo class to represent each todo item.
Display a list of todos.
Create a detailed screen capable of showing information about a todo.
Navigate to the detail screen and pass data about the selected todo.
Define a todo class
To represent todos, create a class containing two pieces of data: title and description.
class Todo {
final String title;
final String description;
const Todo(this.title, this.description);
}
Create a list of todos
Generate 20 todos and display them using a ListView.
final todos = List.generate(
20,
(i) => Todo(
'Todo $i',
'A description of what needs to be done for Todo $i',
),
);
ListView.builder(
itemCount: todos.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todos[index].title),
);
},
);
Create a Todo screen to display the list
Create a StatelessWidget
called TodosScreen
. Require the list of todos within the widget's scope and use ListView.builder
to display the list.
class TodosScreen extends StatelessWidget {
// Requiring the list of todos.
const TodosScreen({super.key, required this.todos});
final List<Todo> todos;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Todos'),
), //passing in the ListView.builder
body: ListView.builder(
itemCount: todos.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todos[index].title),
);
},
),
);
}
}
Create a DetailScreen to display information
Create a StatelessWidget
called DetailScreen. Require a Todo in the constructor and use it to build the UI.
class DetailScreen extends StatelessWidget {
// In the constructor, require a Todo.
const DetailScreen({super.key, required this.todo});
final Todo todo; // Declare a field that holds the Todo.
@override
Widget build(BuildContext context) {
return Scaffold( // Use the Todo to create the UI.
appBar: AppBar(
title: Text(todo.title),
),
body: Padding(
padding: const EdgeInsets.all(16),
child: Text(todo.description),
),
);
}
}
Navigate and pass data to the detail screen
Implement navigation to DetailScreen when a user taps a todo in the list. Pass the selected todo to DetailScreen using Navigator.push().
body: ListView.builder(
itemCount: todos.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todos[index].title),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => DetailScreen(todo: todos[index]),
),
);
},

Let's explore how to navigate to a new screen while passing data to it. Consider a scenario where you want to pass information about a tapped item.
Here's how you can achieve this:
Define a todo class to represent each todo item.
Display a list of todos.
Create a detailed screen capable of showing information about a todo.
Navigate to the detail screen and pass data about the selected todo.
Define a todo class
To represent todos, create a class containing two pieces of data: title and description.
class Todo {
final String title;
final String description;
const Todo(this.title, this.description);
}
Create a list of todos
Generate 20 todos and display them using a ListView.
final todos = List.generate(
20,
(i) => Todo(
'Todo $i',
'A description of what needs to be done for Todo $i',
),
);
ListView.builder(
itemCount: todos.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todos[index].title),
);
},
);
Create a Todo screen to display the list
Create a StatelessWidget
called TodosScreen
. Require the list of todos within the widget's scope and use ListView.builder
to display the list.
class TodosScreen extends StatelessWidget {
// Requiring the list of todos.
const TodosScreen({super.key, required this.todos});
final List<Todo> todos;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Todos'),
), //passing in the ListView.builder
body: ListView.builder(
itemCount: todos.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todos[index].title),
);
},
),
);
}
}
Create a DetailScreen to display information
Create a StatelessWidget
called DetailScreen. Require a Todo in the constructor and use it to build the UI.
class DetailScreen extends StatelessWidget {
// In the constructor, require a Todo.
const DetailScreen({super.key, required this.todo});
final Todo todo; // Declare a field that holds the Todo.
@override
Widget build(BuildContext context) {
return Scaffold( // Use the Todo to create the UI.
appBar: AppBar(
title: Text(todo.title),
),
body: Padding(
padding: const EdgeInsets.all(16),
child: Text(todo.description),
),
);
}
}
Navigate and pass data to the detail screen
Implement navigation to DetailScreen when a user taps a todo in the list. Pass the selected todo to DetailScreen using Navigator.push().
body: ListView.builder(
itemCount: todos.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(todos[index].title),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => DetailScreen(todo: todos[index]),
),
);
},
);

When you need to return data from a new screen, you can utilize the Navigator.pop() method. Here's how you can achieve this:
Define the home screen
Add a button that launches the selection screen
Show the selection screen with two buttons
When a button is tapped, close the selection screen
Show a snackbar on the home screen with the selection

);
}
}
When a button is tapped, close the selection screen:
Update the onPressed() callback for both buttons to close the screen and return the selected option. Use the Navigator.pop()
method, which accepts an optional second argument called result
.
// Close the screen and return "Yep!" as the result.
ElevatedButton(
onPressed: () {
Navigator.pop(context, 'Yep!');
},

Adding a Drawer to a Screen
In Material Design apps, navigation options include tabs and drawers. When space is limited, drawers serve as a practical alternative.
In Flutter, use the Drawer widget along with a Scaffold to implement a layout with a Material Design drawer. Here's how:
Create a Scaffold.
Add a drawer.
Populate the drawer with items.
Programmatically close the drawer.
Create a Scaffold
To add a drawer to your app, use a Scaffold widget. It provides a consistent layout and supports Material Design components. Here's a basic setup:
Scaffold(
appBar: AppBar(
title: const Text('AppBar without hamburger button'),
),
drawer: // Add a Drawer here in the next step.
);
Add a drawer
Let's integrate a drawer into the Scaffold. For a Material Design-compliant drawer, utilize the Drawer widget from the material library. Here's how:
Scaffold(
appBar: AppBar(
title: const Text('AppBar with hamburger button'),
),
drawer: Drawer(
child: // Populate the Drawer in the next step.
),
);
Populate the drawer with items
Let's fill the drawer with content. Utilize a ListView for this purpose. Though you could use a Column
widget, ListView
is preferable as it enables scrolling if the content exceeds the screen space.
Include a DrawerHeader and two ListTile widgets within the ListView. Here's how:
Drawer(
// Add a ListView to the drawer. This ensures the user can scroll
// through the options in the drawer if there isn't enough vertical
// space to fit everything.
child: ListView(
// Important: Remove any padding from the ListView.
padding: EdgeInsets.zero,
children: [
const DrawerHeader(
decoration: BoxDecoration(
color: Colors.blue,
),
child: Text('Drawer Header'),
),
ListTile(
title: const Text('Item 1'),
onTap: () {
// Update the state of the app.
// ...
},
),
ListTile(
title: const Text('Item 2'),
onTap: () {
// Update the state of the app.
// ...
},
),
],
),
);
Close the drawer programmatically
To close the drawer after a user taps an item, utilize the Navigator. When the drawer is opened, Flutter adds it to the navigation stack. Therefore, to close the drawer, call Navigator.pop(context)
.

Let's fill the drawer with content. Utilize a ListView for this purpose. Though you could use a Column
widget, ListView
is preferable as it enables scrolling if the content exceeds the screen space.
Include a DrawerHeader and two ListTile widgets within the ListView. Here's how:
Drawer(
// Add a ListView to the drawer. This ensures the user can scroll
// through the options in the drawer if there isn't enough vertical
// space to fit everything.
child: ListView(
// Important: Remove any padding from the ListView.
padding: EdgeInsets.zero,
children: [
const DrawerHeader(
decoration: BoxDecoration(
color: Colors.blue,
),
child: Text('Drawer Header'),
),
ListTile(
title: const Text('Item 1'),
onTap: () {
// Update the state of the app.
// ...
},
),
ListTile(
title: const Text('Item 2'),
onTap: () {
// Update the state of the app.
// ...
},
),
],
),
);
Close the drawer programmatically
To close the drawer after a user taps an item, utilize the Navigator. When the drawer is opened, Flutter adds it to the navigation stack. Therefore, to close the drawer, call Navigator.pop(context)
.
