I want to put a drawer like this in my Flutter app:
just like https://m3.material.io/develop/flutter
I'm using NavigationRail and it's said that a menu button can be added to open a navigation drawer. Does any knows how to add the menu button and the drawer?
menu button of NavigationRail
thanks.
It's a bit hard to use a regular Scaffold Drawer without the regular scaffold controls, as far as I can tell.
I came up with a solution for your problem, if I understood it correctly. Looks a lot like the spec site, needs a bit of styling.
Took the example from the NavigationRail documentation and added a Visibility widget. Now clicking on the destinations, you can show and hide their child widgets(drawer). No drawer animation though.
import 'package:flutter/material.dart';
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({super.key});
#override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData(
colorSchemeSeed: const Color(0xff6750a4), useMaterial3: true),
home: const NavRailExample(),
);
}
}
class NavRailExample extends StatefulWidget {
const NavRailExample({super.key});
#override
State<NavRailExample> createState() => _NavRailExampleState();
}
class _NavRailExampleState extends State<NavRailExample> {
int _selectedIndex = 0;
NavigationRailLabelType labelType = NavigationRailLabelType.all;
bool showLeading = false;
bool showTrailing = false;
double groupAligment = -1.0;
bool _isClosed = false;
Widget _getWidget(int index) {
switch (index) {
case 1:
return GestureDetector(
child: const Text('Tap!'),
onTap: () => setState(() {
_isClosed = true;
}),
);
case 2:
return const Text('empty');
default:
return ListView(
children: const [
ExpansionTile(
title: Text('whatev'),
children: [Text('1'), Text('2')],
),
ListTile(
title: Text('adfafdafaf'),
)
],
);
}
}
Widget _getPage(int index) {
switch (index) {
case 1:
return const Center(child: Text('sheeesh'));
case 2:
return const Center(child: Text('empty'));
default:
return const Center(child: Text('yolo'),);
}
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Row(
children: <Widget>[
NavigationRail(
selectedIndex: _selectedIndex,
groupAlignment: groupAligment,
onDestinationSelected: (int index) {
setState(() {
_isClosed = (_selectedIndex == index || _isClosed)
? !_isClosed
: _isClosed;
_selectedIndex = index;
});
},
labelType: labelType,
leading: showLeading
? FloatingActionButton(
elevation: 0,
onPressed: () {
// Add your onPressed code here!
},
child: const Icon(Icons.add),
)
: const SizedBox(),
trailing: showTrailing
? IconButton(
onPressed: () {
// Add your onPressed code here!
},
icon: const Icon(Icons.more_horiz_rounded),
)
: const SizedBox(),
destinations: const <NavigationRailDestination>[
NavigationRailDestination(

NavigationRailDestination(

selectedIcon: Icon(Icons.star),
label: Text('Third'),
),
],
),
Visibility(
maintainState: false,
visible: !_isClosed,
child: Row(
children: [
const VerticalDivider(thickness: 1, width: 1),
SizedBox(
height: double.infinity,
width: 200,
child: _getWidget(_selectedIndex),
)
],
),
),
const VerticalDivider(thickness: 1, width: 1),
// This is the main content.
Expanded(

],

),
);
}
}
TabScreen is my main widget in my app that includes a BottomNavigationBar and a PageView to transition between pages.
PageController allows me to change views and everything is fine here, but there is one thing missing. How can I change my PageView controller outside of TabScreen? I'd like to put a button to access my main PageView controller from within my pages.
class _TabsScreenState extends State<TabsScreen> {
bool _isloading = true;
int? _selectedIndex;
List<Widget>? _pages = [
HomeScreen(),
CurrenPlanDetail(),
Container(),
ProfileScreen(),
SettingScreens(),
];
PageController? _pageController;
#override
void initState() {
_selectedIndex = 0;
_pageController = PageController(initialPage: _selectedIndex!);
}
}
Widget build(BuildContext context) {
return Scaffold(
body: PageView(
controller: _pageController,
children: _pages!,
physics: NeverScrollableScrollPhysics(),
),
bottomNavigationBar: Visibility(
visible: !_isloading,
child: BottomNavigationBar(
type: BottomNavigationBarType.fixed,
selectedItemColor: kNewPurple,
//unselectedItemColor: Colors.grey,
currentIndex: _selectedIndex!,
onTap: (value) {
setState(() {
_selectedIndex = value;
_pageController!.jumpToPage(_selectedIndex!);
});
},
backgroundColor: Colors.grey[300],
items: [
BottomNavigationBarItem(
icon: Icon(
Ionicons.home_outline,
size: 15.sp,
),
label: 'Home'),
BottomNavigationBarItem(
icon: Icon(
Ionicons.reader_outline,
size: 15.sp,
),
label: 'Plan'),
BottomNavigationBarItem(
icon: ElevatedButton(
style: ElevatedButton.styleFrom(
shape: CircleBorder(),
fixedSize: Size(50, 50),
),
onPressed: () {
showModalBottomSheet(
context: context,
builder: (context) {
return FloatingButton();
});
},
child: Icon(Ionicons.add)),
label: ''),
BottomNavigationBarItem(
icon: Icon(
Ionicons.happy_outline,
size: 15.sp,
),
label: 'Profile'),
BottomNavigationBarItem(
icon: Icon(
Ionicons.settings_outline,
size: 15.sp,
),
label: 'Setting'),
],
),
),
);
}
}
for example, somewhere in my app, I'd like to put a button and pass a function like this :
_pageController!.jumpToPage(1);
Define PageController as static and
TabScreen.pageController.jumpToPage(1);
I am getting The following error while Run my app default page (Homepage) .

Please help.
the problem is, you are getting your data in the initState method, but your widget's build is being completed before initializing the data to _freespace, and that's why the error is appearing.
as a solution, I suggest removing _getStorgeInfo() call from initState, and implementing the following structure:
#override
Widget build(BuildContext context) {
return Scaffold(
key: scaffoldKey,
endDrawerEnableOpenDragGesture: false, // This way it will not open
// endDrawer: Drawer(),
drawer: new Drawer(
...
),
appBar: AppBar(
...
),
body: SafeArea(
child: Container(
padding: EdgeInsets.all(15.0),
child: FutureBuilder(
future: _getStorgeInfo(),
builder: (context, snapshot) {
if(snapshot.connectionState!=ConnectionState.Done) return CircularProgressIndicator();
return _widgetBody;
},
),
),
));
}
Hi guys I'm trying to build an app with flutter, so I have two screens HomeScreen() and RoutineScreen(). The first one is a Scaffold and in the body has a child Widget (a ListView called RoutinesWidget()) with all the routines. And the second one is to create a routine. The thing is, that when I create the routine, I use a button to pop to the HomeScreen() but it doesn't refresh the ListView (I'm guessing that it's because when I use Navigator.pop() it refreshes the Scaffold but not the child Widget maybe?)
HomeScreen() code here:

import 'package:workout_time/Screens/routine_screen.dart';
class HomeScreen extends StatefulWidget {
#override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
int _selectedIndex = 0;
List<Widget> _views = [
RoutinesWidget(),
StatisticsWidget(),
];
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: kThirdColor,
appBar: AppBar(
leading: Icon(Icons.adb),

onPressed: () => Navigator.push(context,
MaterialPageRoute(builder: (context) => SettingsScreen()))),
],
),
body: _views[_selectedIndex],
floatingActionButton: (_selectedIndex == 1)

onPressed: () async {
await Navigator.push(
context,
MaterialPageRoute(
builder: (context) => RoutineScreen(null)));
setState(() {});

Any idea what can I do to make it work? Thank you
Make it simple
use Navigator.pop() twice
so that the current class and old class in also removed
from the stack
and then use Navigator.push()
When you push a new Route, the old one still stays in the stack. The new route just overlaps the old one and forms like a layer above the old one. Then when you pop the new route, it will just remove the layer(new route) and the old route will be displayed as it was before.
Now you must be aware the Navigator.push() is an asynchronous method and returns a Future. How it works is basically when you perform a Navigator.push(), it will push the new route and will wait for it to be popped out. Then when the new route is popped, it returns a value to the old one and that when the future callback will be executed.
Hence the solution you are looking for is add a future callback like this after your Navigator.push() :
Navigator.push(context,
MaterialPageRoute(builder: (context) => SettingsScreen())
).then((value){setState(() {});}); /// A callback which is executed after the new route will be popped. In that callback, you simply call a setState and refresh the page.
I used a bottom navigation bar in flutter using this widget,
how can I make that bottom navigation bar show on all the pages?
and can I make it appear when I choose a page from drawer??
please help me,
You can actually achieve this with the pageview widget
https://api.flutter.dev/flutter/widgets/PageView-class.html
With this, you can have all the pages inside one class and build the bottom navigation bar underneath the pageview widget. By default the pages are swipeable but you can disable it doing
Scaffold(
body:
Container(
child:
Column(
children: <Widget> [
PageView(
physics:new NeverScrollableScrollPhysics())
controller: _controller,
children: [
MyPage1(),
MyPage2(),
MyPage3(),
],
),
googleNavBar()
]
)
);
May I suggest you to use flutter builtin BottomNavigationBar widget instead of third party widget.
Here is my code you can modify as per you requirement. Hope this will help.
