After I tap an item in the Scaffold's drawer I want it to automatically hide itself. How do I do it in Flutter?

As of flutter v3.27.X
To close the Scaffold's drawer after tapping an item use the following example
if (Scaffold.of(context).isDrawerOpen) {
Scaffold.of(context).closeDrawer();
}

To close the Scaffold's drawer after an item tap, you can use the Navigator.pop(context) method. Here's an example of how you might use it:
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Drawer Example'),
),
drawer: Drawer(
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
DrawerHeader(
child: Text('Drawer Header'),
decoration: BoxDecoration(
color: Colors.blue,
),
),
ListTile(
title: Text('Item 1'),
onTap: () {
// Do something when the item is tapped
// Close the drawer
Navigator.pop(context);
},
),
ListTile(
title: Text('Item 2'),
onTap: () {
// Do something when the item is tapped
// Close the drawer
Navigator.pop(context);
},
),
],
),
),
body: Center(
child: Text('Home Page'),
),
);
}
}

Simply add Navigator.pop to your button or widget you tap
Navigator.pop(context);

First Pop widget, after that Push your route it will automatically close the Drawer when you come back next time.
Navigator.pop(context); // Widget will be poped
Navigator.pushNamed(context, '/routename'); // New Route will be pushed

ListTile(
title: Text(
'Notification Setting',
style: TextStyle(
fontSize: 16.0, color: HexColor(HexColor.gray_text)),
),
leading: Icon(
Icons.notifications_outlined,
size: 24.0,
color: HexColor(HexColor.primarycolor),
),
onTap: () {
_scaffoldKey.currentState?.openEndDrawer();
Navigator.push(context, MaterialPageRoute(builder: (context) {
return NotificationSettingActivity();
}
));
},
),

First create a ScaffoldState key
GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
Scaffold(
key: _scaffoldKey,)
Now you can open and close the drawer using the toggleDrawer()
method.
for the left drawer
toggleDrawer() async {
if (_scaffoldKey.currentState.isDrawerOpen) {
_scaffoldKey.currentState.openEndDrawer();
} else {
_scaffoldKey.currentState.openDrawer();
}
}
for the right drawer
toggleDrawer() async {
if (_scaffoldKey.currentState.isDrawerOpen) {
_scaffoldKey.currentState.openDrawer();
} else {
_scaffoldKey.currentState.openEndDrawer();
}
}

Well its quite Easy
Problem Statement : In default Home Page when someone presses back button , (if drawer is open) it is closed, else a prompt is thrown asking for Exit Application "Yes" and "No".
Solution
Add
GlobalKey _scaffoldKey = new GlobalKey();
Make Function Future _onWillPop() async handling the required problem statement
Call key and onWillPop as given in the below source code
See Through full source code For the additions done related to this problem statement in source code
import 'package:flutter/material.dart';
class HomePage extends StatefulWidget {
@override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
Future<bool> _onWillPop() async {
if(_scaffoldKey.currentState != null && _scaffoldKey.currentState!.isDrawerOpen){
return true;
}
return (await showDialog(
context: context,
builder: (context) => new AlertDialog(
title: new Text('Leaving our App?'),
content: new Text('Are you sure you want to Exit?'),
actions: <Widget>[
TextButton(
onPressed: () => Navigator.of(context).pop(false),
child: new Text('No'),
),
TextButton(
onPressed: () => Navigator.of(context).pop(true),
child: new Text('Yes'),
),
],
),
)) ??
false;
}
@override
Widget build(BuildContext context) {
return Scaffold(
key: _scaffoldKey,
body: WillPopScope(
onWillPop: _onWillPop,
child: Container(
child: Center(
child: Text("Welcome My App"),
),
),
),
drawer: SideDrawer(),
);
}
}

You can use the below code according to your requirement.
When you want to remove and push new route:
Navigator.of(context).popAndPushNamed('/routeName');
When you want to just pop:
Navigator.of(context).pop();

Navigate.of(context).pop();
OR
Navigate.pop(contex);
must be the first in onTap() function
for example :
onTap: () {
Navigator.of(context).pop();//before pushing to any other route
Navigator.push(
context,
MaterialPageRoute(
builder: (BuildContext context) => Screen2(),
),
);
}

This is the answer
First in Class
GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
Second In Widget
Scaffold(key: _scaffoldKey,)
Third in code
if (_scaffoldKey.currentState.isDrawerOpen) {
_scaffoldKey.currentState.openEndDrawer();
}

I think what the OP is possibly trying to say is that even though Navigator.of(context).pop() and Navigator.pop(context) should work, they aren't in his case- I'm having the same issue.
Early on in a project the drawer works as it should - opening and closing properly. Since several changes have been made (none directly to the drawer or its scaffold) the drawer is no longer closing with Navigator.of(context).pop() and Navigator.pop(context).
I did a little more digging and found that instead of using Navigator.pop you can use Scaffold.of(context).openEndDrawer to close the drawer - even though it doesn't seem like it should. I've never used this function until now but it works perfectly. Hope this helps anyone with the same issue.

If you simply want to close the Drawer
, you can use any of the following:
Navigator.pop(context);
Navigator.of(context).pop();
And if you want to navigate to a new page, you can use
Navigator.popAndPushNamed(context, "/new_page");
or
Navigator.pop(context);
Navigator.push(context, MaterialPageRoute(builder: (_) => Page2()));

Shorthand for closing the drawer and navigating to a new route:
Navigator.popAndPushNamed(context, '/newroute');

For the lastest Flutter version (v0.3.2 when I am writing this), the implementation changed a bit and Navigator.pop()
now requires a given context.
Navigator.pop(context) is the typical usage for closing a route.
Navigator.pop(context, true) is the usage for closing a route with a returned result.
See Drawer Class and example on Flutter's Cookbook.

Navigator.of(context).pop()
should do what you want :)

Navigator.pop() will pop the Drawer
route off the stack and cause it to close.
