I want to make logout and settings in bottom of drawer navigation but I have tried many suggestion but doesn't work at all
any suggestion?
This is my drawer navigation
Drawer(
child: ListView(
padding: EdgeInsets.zero,
children: <Widget>[
_createHeader(),
_createDrawerItem(icon: Icons.event, text: 'Event', onTap: () => Navigator.pushReplacementNamed(context, Routes.event)
),
Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
_createFooterItem(icon: Icons.event, text: 'Settings', onTap: () => Navigator.pushReplacementNamed(context, Routes.event)),
_createFooterItem(icon: Icons.event, text: 'Logout', onTap: () => Navigator.pushReplacementNamed(context, Routes.event))
],
),
],
),
);
this is my widget for header
Widget _createHeader() {
return DrawerHeader(
margin: EdgeInsets.zero,
padding: EdgeInsets.zero,
decoration: BoxDecoration(
image: DecorationImage(
fit: BoxFit.fill,
image: AssetImage('res/images/drawer_header_background.png'))),
child: Stack(children: <Widget>[
Positioned(
bottom: 12.0,
left: 16.0,
child: Text("Flutter Step-by-Step",
style: TextStyle(
color: Colors.white,
fontSize: 20.0,
fontWeight: FontWeight.w500))),
]));
}
and this is my widget for footer item
Widget _createFooterItem({IconData icon, String text, GestureTapCallback onTap}){
return ListTile(
title: Row(
children: <Widget>[
Icon(icon),
Padding(
padding: EdgeInsets.only(left: 8.0),
child: Text(text),
)
],
),
onTap: onTap,
);
}
You can change the ListView to a Column then add a Expanded widget with a child Container
Drawer(
child: Column( // Changed this to a Column from a ListView
children: <Widget>[
_createHeader(),
ListTile(title: Text('First item')),
Expanded(child: Container()), // Add this to force the bottom items to the lowest point
Column(
children: <Widget>[
_createFooterItem(
icon: Icons.event,
text: 'Settings',
onTap: () => Navigator.pushReplacementNamed(context, '/')),
_createFooterItem(
icon: Icons.event,
text: 'Logout',
onTap: () => Navigator.pushReplacementNamed(context, '/'))
],
),
],
),
);

PopupMenuButton<String>(
///Icon
child: SizedBox(
child: Stack(
children: [
const Icon(
Icons.notifications_outlined,
),
Container(
child: Container(
child: Padding(
padding: const EdgeInsets.all(0.0),
child: Center(
child: Text(
''
),
),

)
],
),
),
onSelected: (value) {},
itemBuilder: (BuildContext context) {
///generating list on the fly
var myList = someList!.map((listItem) {
return PopupMenuItem<String>(
value: listItem.id.toString(),
child: SizedBox(
child: Column(
children: [
Text(
listItem.name!,
),
],
),
),
);
}).toList();
var closeButtonList = [
PopupMenuItem<String>(
child: Column(
children: [
Align(
alignment: Alignment.centerRight,
child: IconButton(
onPressed: Navigator.of(context).pop,
icon: const Icon(
Icons.close,
),
),
),
],
),
),
///appending list using spread operator
...myList
];
return closeButtonList;
},
This code works fine and displays a cross(close) icon as the first element of the list.
The problem is when I scroll the list, the icon get scrolled and disappears from the screen.
How can I make it fixed while the rest of the list is scrollable?
I am using a package fab_circular_menu, That package is for an animated floating action button which opens up a circular menu. within it I want a widget as a menu item such that there is an icon and a text below. the icon is centered with text.
e.g.
How can I achieve this, as of now I am using the code below but it does not work well with different screen size.
FlatButton(
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(100),
),
padding: EdgeInsets.only(bottom: 15),
onPressed: () async {
await _auth.signOut().then((value) {
Navigator.of(context).popUntil((route) => route.isFirst);
});
},
child: Stack(
overflow: Overflow.visible,
children: <Widget>[
Icon(Icons.power_settings_new),
Positioned(
bottom: -12,
right: -10,
child: Text('Logout'),
),
],
),
),
Another Solution which could use in many ways
Wrap(
direction: Axis.vertical,
crossAxisAlignment: WrapCrossAlignment.center,
children: <Widget>[
Icon(Icons.power_settings_new),
Text('Logout'),
],
),
You can achieve this result with Column widget instead of Stack.
Here is the example:
.....
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Icon(Icons.power_settings_new),
Text('Logout'),
],
),
Short answer:
Column(
mainAxisSize: MainAxisSize.min,
children: [
Icon(Icons.call),
SizedBox(height: 4), // spacing between two
Text('Call Icon'),
],
)
Long answer:
Copy this class:
class TextWithIcon extends StatelessWidget {
final IconData icon;
final String text;
final double spacing;
const TextWithIcon({Key key, this.icon, this.text, this.spacing = 2}) : super(key: key);
#override
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.all(8),
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
Icon(icon),
SizedBox(height: spacing),
Text(text),
],
),
);
}
}
Usage:
TextWithIcon(
icon: Icons.call,
spacing: 6, // Space between icon and text
text: 'Call Icon',
)
You can use columns for this like:
FlatButton(
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(100),
),
padding: EdgeInsets.only(bottom: 15),
onPressed: () async {
await _auth.signOut().then((value) {
Navigator.of(context).popUntil((route) => route.isFirst);
});
},
child: Column(
children: <Widget>[
Icon(Icons.power_settings_new),
SizedBox(height:10), // set height according to your needs
Text('Logout'),
],
),
),
I have been trying to put a line indicator on the left most margin of the card in my flutter app. I've tried a lot of things but didn't work.
There's an exact question here, which is actually the same issue I've been trying to solve.
The problem with the accepted solution is that it restricts the height of the hardcoded value, which I don't want. Rather the color should automatically fill the height of the card.
The Problem
I've tried all the three solutions and none of them fit my use case.
Output from first solution
Here I've to hardcode the value to something larger so that all the text being displayed lies well inside it. That's something I feel is not a solution.
Card(
key: ObjectKey(noteList[index]),
elevation: 2.0,
child: IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Container(
width: 4,
color: Color(noteList[index].intcolor),
),
Flexible(
flex: 100,
child: ListTile(
~~~~~~~~~~~~~~~~~ SNIP ~~~~~~~~~~~~~~~~~~~~~~~~
chip goes outside
Output from Second solution
This doesn't show anything at all.
Card(
key: ObjectKey(noteList[index]),
elevation: 2.0,
child: Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
constraints: BoxConstraints.expand(),
color: Color(noteList[index].intcolor),
),
),
Flexible(
flex: 100,
child: ListTile(
~~~~~~~~~~~~~~~~~ SNIP ~~~~~~~~~~~~~~~~~~~~~~~~
No output at all
Output from last solution
There's no color from the container.
There's no color from the container
Thanks a lot.

Added code and repo for easy replication.

class HomePage extends StatelessWidget {
final List<String> notes;
HomePage(this.notes);
Widget build(BuildContext context) {
return ListView.builder(
itemCount: notes.length,
itemBuilder: (context, pos) {
return Padding(
padding: EdgeInsets.only(bottom: 16.0),

Perhaps one way of doing it is to use Stack
ListView.builder(
itemCount: notes.length,
itemBuilder: (context, pos) {
return Padding(
padding: EdgeInsets.all(8),
child: Stack(
children: <Widget>[
Card(
margin: EdgeInsets.zero,
child: ListTile(
leading: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Icon(Icons.receipt),
],
),
title: Text(
notes[pos],
),
subtitle: Row(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Text(notes[pos].substring(0, 10)),
if ((pos % 2) == 0)
Chip(
avatar: CircleAvatar(
backgroundColor: Colors.grey.shade800,
child: Icon(Icons.timer),
),
label: Text('2FA'),
),
],
),
trailing: Padding(
padding: EdgeInsets.all(10),
child: Wrap(
spacing: 10,
direction: Axis.vertical,
alignment: WrapAlignment.spaceEvenly,
children: <Widget>[
IconButton(
icon: Icon(
Icons.check,
color: Colors.grey,
),
onPressed: () {},
)
]),
),
onTap: () {},
),
),
Positioned(
top: 0,
bottom: 0,
child: Container(
width: 5,
color: Colors.green,
),
)
],
),
);
},
)
Output
i am trying to add item in list when i click on add button, all code is ok, but i am getting error invalid reference to this expression. i am using stateful widget.
List<Widget> _listSection = [];
body: Container(
child: Stack(
children: [
FloatingActionButton(
onPressed: () {
_listSection.add(
listSectionMethod(
"title three", "hello from click", Icons.forward),
);
setState(() {});
},
),
],
),
),
),
);
}
}
Widget listSection = Container(
margin: EdgeInsets.only(top: 210),
child: ListView(
children: [
Column(
children: [
Column(
children: this._listSection, // ----> ERROR HERE
),
],
),
],
),
);
List Section Method:
Card listSectionMethod(String title, String subtitle, IconData icon) {
return new Card(
child: ListTile(
title: Text(
title,
style: TextStyle(fontWeight: FontWeight.bold),
),
subtitle: Text(subtitle),
trailing: Icon(
icon,
color: Colors.blue,
),
),
);
}
change this:
Widget listSection = Container(
margin: EdgeInsets.only(top: 210),
child: ListView(
children: [
Column(
children: [
Column(
children: this._listSection,
),
],
),
],
),
);
for this:
Widget listSection() {
return Container(
margin: EdgeInsets.only(top: 210),
child: ListView(
children: [
Column(
children: this._listSection,
),
],
),
);
}
So I'm trying to remove the bottom margin of raisedButton so it will look like it is merged with the card below it.
here's what it looks like
here is my code
Expanded(
child: Card(
elevation: 5,
// shape:
// RoundedRectangleBorder(borderRadius: BorderRadius.circular(22)),
child: Column(
children: <Widget>[
Row(
children: <Widget>[
Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Apakah anak sudah bisa ... ?",
style: TextStyle(fontWeight: FontWeight.bold)),
),
],
),
Row(
children: <Widget>[
Expanded(
child: RaisedButton(
child: Text(
"Iya",
style: TextStyle(color: Colors.white),
),
color: Colors.green[300],
onPressed: () {}),
),
Expanded(
child: RaisedButton(
child: Text(
"Tidak",
style: TextStyle(color: Colors.white),
),
color: Colors.red[200],
onPressed: () {}))
],
)
],
),
),
)
or do you guys have any other alternative solution to achieve that?
You can explicitly set your Row height to match the height of your RaisedButton. Simply wrap it inside a Container and add the height attribute.
If you want to, you can access the default height by using Theme.of(context).buttonTheme.height. Theme.of returns the ThemeData used in the current context.
Here a minimal example:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: Container(
child: Card(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('Test'),
Container(
height: Theme.of(context).buttonTheme.height,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
RaisedButton(
onPressed: () {},
child: Text('Yes'),
color: Colors.green,
),
RaisedButton(
onPressed: (){},
child: Text('No'),
color: Colors.red,
)
],
),
),
],
)
),
),
)),
);
}
}
I had the same problem. NikasPor's answer didnt work for me, unfortunately. The way I fixed it is by seeting the crossAxisAlignment on the row to .stretch
Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
children:[ /* Buttons Here */]
)
