how to change icon colour on PopupMenuButton, I have used Theme with iconTheme but it doesn't affect the icon on CheckedPopupMenuItem nor PopupMenuItem.
Scaffold(
backgroundColor: Colors.transparent,
appBar: AppBar(
elevation: 0.0,
backgroundColor: Colors.transparent,
actions: <Widget>[
Theme(
data: Theme.of(context).copyWith(
cardColor: Colors.indigo,
iconTheme: IconThemeData(color: Colors.white),
),
child: ListTileTheme(
iconColor: Colors.white,
child: PopupMenuButton<String>(
onSelected: _showCheckedMenuSelections,
itemBuilder: (BuildContext context) => <PopupMenuEntry<String>>[
CheckedPopupMenuItem<String>(
value: _checkedValue1,
checked: _showRoles,
child: Text(_checkedValue1, style: Theme.of(context).textTheme.body1),
),
const PopupMenuDivider(),
PopupMenuItem<String>(
value: 'Get Link',
child: ListTile(
leading: Icon(Icons.phonelink),
title: Text('Get link', style: Theme.of(context).textTheme.body1),
),
),
],
),
),
),
],
),
The result is look like this :
Just do this
appBar: AppBar(
iconTheme: IconThemeData(color: Colors.white, size: 10.0),
elevation: 4.0,
backgroundColor: Colors.black,
)
You can wrap the Icon widget inside IconButton which provides color property to change the icon color. Sample code below:
value: 'Get Link',
child: ListTile(
leading: IconButton(
icon: Icon(Icons.phonelink,
color: Colors.blue,),
onPressed: () {},
),
title: Text('Get link', style: Theme.of(context).textTheme.body1),
),

I'm trying to recreate this ui template in which a I have list under that list is a list of items and after all the items is a container displaying a summary. I'm trying to achieve this by wrapping the listview.builder and a container inside a list view however it doesn't show anything. This is the code.
Container(
height: 550.0,
child: ListView(
children: <Widget>[
Expanded(
child: ListView.builder(
physics: ClampingScrollPhysics(),
scrollDirection: Axis.vertical,
itemCount: itemList.length,
itemBuilder: (BuildContext context, int index) {
return SingleItem(
itemImage: itemList[index]['image'],
itemPrice: itemList[index]['price'],
itemName: itemList[index]['name'],
itemCode: itemList[index]['code'],
);
},
),
),
Expanded(
child: Container(
color: Colors.brown,
),
)
],
)
),
import 'package:flutter/material.dart';

I have four cards simply now i want a button in the end and center how would it would be
Insert GridView.counter in a Column
set shrinkWrap and primary property as true
put your button inside Column and below gridview, not inside button.
put the button in Center Widget / set crossAxisAlignment: CrossAxisAlignment.center
import 'package:flutter/material.dart';
class Test extends StatefulWidget {
#override
_TestState createState() => _TestState();
}
class _TestState extends State<Test> with SingleTickerProviderStateMixin{
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Page - 2"),
),
body: SafeArea(
child: Column(
children: <Widget>[
GridView.count(
shrinkWrap: true,
primary: true,
crossAxisCount: 2,
children: <Widget>[
Container(
color: Colors.red,
),
Container(
color: Colors.green,
),
Container(
color: Colors.blue,
),
Container(
color: Colors.yellow,
),
],
),
Divider(
color: Colors.grey.shade600,
),
Center(
child: RaisedButton(
child: Text("Button"),
onPressed: (){},
),
)
],
),
),
);
}
}
Am writing a very basic app that just displays numbers on the screen and you can increase and decrease the value of this number with some buttons.
Works fine, except for some reason the text display often goes nuts. I'll show you what I mean:
The above text is trying to display a value of 20, but it is struggling for some reason, as you can see.
This only appears to be happening with double-digit or higher values. My code:
class _SinglePlayerModeParentState extends State<SinglePlayerMode> {
#override
void initState() {
super.initState();
SystemChrome.setEnabledSystemUIOverlays([]);
SystemChrome.setPreferredOrientations([DeviceOrientation.landscapeLeft,]);
}
#override
Widget build(BuildContext context) {
Widget numberDisplay = GestureDetector(
onTap: () {
print("GestureDetector");
_incrementBy1();
},
child: Center(child: Text(_numberValue.toString(),
style: TextStyle(
fontSize: 200.0,
color: Colors.white,
),
),
),
);
This code was already displaying these text issues before I rearranged the code to include the following as well:
Widget buttonRow() {
return Row(
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.end,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[
Padding(
padding: EdgeInsets.only(left: 40.0, right: 20.0),
child: FloatingActionButton(
heroTag: null,
onPressed: _numberValueMinus5,
child: Text('-5'),
),
),
Padding(
padding: EdgeInsets.only(left: 20.0, right: 40.0),
child: FloatingActionButton(
heroTag: null,
onPressed: _numberValueMinus1,
child: Text('-1'),
),
),
],
),
Row(
children: <Widget>[
Padding(
padding: EdgeInsets.only(left: 40.0, right: 20.0),
child: FloatingActionButton(
heroTag: null,
onPressed: _numberValuePlus1,
child: Text('+1'),
),
),
Padding(
padding: EdgeInsets.only(left: 20.0, right: 40.0),
child: FloatingActionButton(
heroTag: null,
onPressed: _numberValuePlus5,
child: Text('+5'),
),
),
],
),
],
);
}
return MaterialApp(
title: 'Bean Counter',
home: Scaffold(
backgroundColor: Colors.blueAccent,
body: Column(
children: [
Padding(
padding: EdgeInsets.only(top: 90.0, bottom: 40.0),
child: numberDisplay,
),
buttonRow(),
],
),
),
);
}
Not sure what I can do differently here, it's just text!
Any thoughts?
Edit: Testing the FittedBox solution.
#override
Widget build(BuildContext context) {
Widget numberDisplay = GestureDetector(
onTap: () {
print("GestureDetector");
_incrementBy1();
},
child: Center(
child: FittedBox(
fit: BoxFit.scaleDown,
child: Text(_numberValue.toString(),
style: TextStyle(
fontSize: 200.0,
color: Colors.white,
),
),
),
),
);
}
Results: this is trying to display the number 30:
As you can see, it still isn't displaying properly. I also tried BoxFit.contain, same issue. Information obtained from this reference: https://docs.flutter.io/flutter/painting/BoxFit-class.html
Any other ideas guys? Or did I implement FittedBox incorrectly?
Edit: Tried with AutoSizeText, as recommended below. Code:
#override
Widget build(BuildContext context) {
Widget scoreText = GestureDetector(
onTap: () {
print("GestureDetector");
_incrementBy1();
},
child: Center(
child: AutoSizeText(_numberValue.toString(),
style: TextStyle(
fontSize: 200.0,
color: Colors.white,
),
),
),
);
Results:
Argh! Displaying text on a clear screen. Level: difficult.
I am calling this dialog while getting data from server. This dialog box is having white spaces around it. I can I remove this white space around my dialog box. Here is my code.
var bodyProgress = new Container(
decoration: new BoxDecoration(
color: Colors.blue[200],
borderRadius: new BorderRadius.circular(10.0)
),
width: 300.0,
height: 200.0,
//color: Colors.blue,
alignment: AlignmentDirectional.center,
child: new Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Center(
child: new SizedBox(
height: 50.0,
width: 50.0,
child: new CircularProgressIndicator(
value: null,
strokeWidth: 7.0,
),
),
),
new Container(
margin: const EdgeInsets.only(top: 25.0),
child: new Center(
child: new Text(
"Signing up...",
style: new TextStyle(
color: Colors.white
),
),
),
),
],
),
);
Here I am calling this dialog. I've tried with both AlertDialog() and SimpleDialog() having same issue with both.
showDialog(context: context, child: new AlertDialog(
content: bodyProgress,
));
Inside AlertDialog set contentPadding 0
contentPadding: EdgeInsets.zero,
make title to have Container, and add
width: MediaQuery.of(context).size.width,
Then give 0 (or what value you want to have for horizontal patting) to insetPadding like this:
insetPadding: EdgeInsets.symmetric(horizontal: 0),
Below is my example show dialog code, contains alertDialog with horizontal padding = 15 :
Future<void> _showLogoutDialog(BuildContext context) async {
return showDialog<void>(
context: context,
barrierDismissible: true,
builder: (BuildContext context) {
return AlertDialog(
titlePadding: EdgeInsets.only(top: 12, left: 24, right: 12),
contentPadding: EdgeInsets.only(top: 12, left: 24, bottom: 20),
insetPadding: EdgeInsets.symmetric(horizontal: 15),
titleTextStyle: TextStyle(
color: ColorStyles.primary_blue500,
fontFamily: 'Muli',
fontWeight: FontWeight.w500,
fontStyle: FontStyle.normal,
fontSize: 16.0,
),
contentTextStyle: TextStyle(
color: ColorStyles.grey2,
fontFamily: 'Muli',
fontWeight: FontWeight.w400,
fontStyle: FontStyle.normal,
fontSize: 14.0,
),
title: Container(
width: screenUsableHeight(context),
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text('Log out'),
IconButton(
icon: Icon(
Icons.close,
color: ColorStyles.grey2,
size: 28,
),
onPressed: () => Navigator.of(context).pop(),
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
tooltip: "close",
)
],
),
),
//EN: Logging out
content: SingleChildScrollView(
child: ListBody(
children: <Widget>[
Text('Do you want to leave?'),
],
),
),
actions: <Widget>[
FlatButton(
child: Text(
'Yes',
style: TextStyle(
color: ColorStyles.primary_blue500,
fontFamily: 'Muli',
fontWeight: FontWeight.w500,
fontStyle: FontStyle.normal,
fontSize: 16.0,
),
), //EN: Yes
onPressed: () {
_logOut(context);
},
),
FlatButton(
child: Text(
'No',
style: TextStyle(
color: ColorStyles.grey2,
fontFamily: 'Muli',
fontWeight: FontWeight.w500,
fontStyle: FontStyle.normal,
fontSize: 16.0,
),
), //EN: No
onPressed: () {
Navigator.of(context).pop();
},
),
],
);
},
);
}
This looks like:
display of alert dialog
titlePadding: EdgeInsets.zero,
contentPadding: EdgeInsets.zero,
Don't use AlertDialog at all. Just send bodyProgress to showDialog
showDialog(context: context, builder: (_) => bodyProgress,);
add the file to your project https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/material/dialog.dart, use the CustomAlertDialog and set the contentPadding to 0.0 by using EdgeInsets.all(0.0), finally adjust the border raidius to that of your bodyprogress
use like this ->
using get: ------------->
Get.generalDialog(
pageBuilder: (BuildContext buildContext, Animation animation,
Animation secondaryAnimation) =>
AlertDialog(
contentPadding: EdgeInsets.zero,
// this padding user for outside of alert padding
insetPadding: EdgeInsets.symmetric(horizontal: 10),
content: Container(
height: Get.height - 300, // Change as per your requirement
width: Get.width, // Change as per your requirement
child: <Your Widget>
),
),
));
using alert dialog:------>
CustomAlertDialog(
content: new Container(
width: 260.0,
height: 230.0,
decoration: new BoxDecoration(
shape: BoxShape.rectangle,
color: const Color(0xFFFFFF),
borderRadius:
new BorderRadius.all(new Radius.circular(32.0)),
),
child: <Your widget>
),
);
});
