I want to set divider between PopupMenuItem and I want to change styling PopupMenuDivider color which that have default color. How can i do this ?
You can do this very easily using the Theme class, using which you can change the icon color, text color and Default PopupMenuDivider color.
Again, you can easily do this on Divider at PopupMenuItem using PopupMenuDivider.
actions: [
Theme(
data: Theme.of(context).copyWith(
dividerTheme: DividerThemeData(
color: Colors.black,
),
iconTheme: IconThemeData(color: Colors.white),
textTheme: TextTheme().apply(bodyColor: Colors.white),
),
child: PopupMenuButton<int>(
color: Colors.indigo,
//onSelected: (item) => onSelected(context, item),
itemBuilder: (context) => [
PopupMenuItem<int>(
value: 0,
child: Text('Settings'),
),
PopupMenuDivider(),
PopupMenuItem<int>(
value: 1,
child: Text('Share'),
),
PopupMenuDivider(),
PopupMenuItem<int>(
value: 2,
child: Row(
children: [
Icon(Icons.logout),
const SizedBox(width: 8),
Text('Sign Out'),
],
),
),
],
),
),
],

I've tried to change the child from column to other types but still it didn't work. I'm not sure what's causing the error here but I'm suspecting its the screens[_currentindex] placement. Also when i click on one of the items in the bottom bar. The background color (dark blue) doesn't change to the color of my desired page. but current content disappears.
class _MyStatefulWidgetState extends State<focalPointProfile> {
**int _currentIndex = 0;**

return Scaffold(

}
class _MyStatefulWidgetState extends State<focalPointProfile>
cant be the same as here
**final List<Widget> screens = [
dashboardScreen(),
focalPointProfile(),
mentorRegistrationScreen(), ];

How can I narrow the width of the popup menu in the navbar?
How can I zoom the icon and text?
I can't open the width tag, I think a different customization is required.
actions: <Widget>[
PopupMenuButton<_MenuValues>(
color: const Color(0xFF212121),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(15.0))
),
itemBuilder: (BuildContext context) => [
PopupMenuItem(
child: ListTile(
leading: Icon(Icons.settings, color: Colors.white),
title: Text("Settings", style: TextStyle(color: Colors.white)),
),
value: _MenuValues.settings
),
],
onSelected: (value) {
switch(value) {
case _MenuValues.settings:
Navigator.of(context).push(MaterialPageRoute(
builder: (context) => settings(),
));
break;
}
},
),
],
use sizedBox
PopupMenuItem(
value: 1,
// row has two child icon and text.
child: SizedBox(
width: 500,
child: Row(
children: [
Icon(Icons.settings , size: 10,),
Text("Settings", style: TextStyle(fontSize: 10),)
],
),
)
),
],
I tried to change the text color of CupertinoDatePicker following this answer and it was successful but when i wanted to change the color of CupertinoTimerPicker it did not change it i want the color of text to be white and the style to be same as the one below
showDialog(
context: context,
builder: (context) {
return AlertDialog(
backgroundColor: const Color(0xff2e2e2e),
title: Column(
children: [
Text(
'Set Duration',
style: TextStyle(
color: Colors.white, fontSize: 16),
),
Divider(
height: 6,
color: Colors.white,
),
],
),
content: CupertinoTheme(
data: CupertinoThemeData(
brightness: Brightness.light,
textTheme: CupertinoTextThemeData(
dateTimePickerTextStyle: TextStyle(color: Colors.red),
),
),
child: CupertinoTimerPicker(
mode: CupertinoTimerPickerMode.hms,
minuteInterval: 1,
secondInterval: 1,
initialTimerDuration: Duration(hours:0, minutes: 0, seconds: 0),
onTimerDurationChanged: (Duration changedTimer) {
setState(() {
initialTimer = changedTimer;
});
},
),
),
);
},
);
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
backgroundColor: Colors.white,
leading: const Icon(Icons.home),
automaticallyImplyLeading: true,
title: const Text('test app'),
foregroundColor: Colors.black,
actions: [
IconButton(
onPressed: () {},
icon: const Icon(Icons.menu),
),
],
),
body: Container(
child: Column(
children: [
Row(
children: [
const Text(
'New',
style: TextStyle(
color: Colors.black54,
fontSize: 40,
fontWeight: FontWeight.bold,
fontStyle: FontStyle.italic,
height: 2,
shadows: [
Shadow(color: Colors.black12, offset: Offset(4, 10))
]),
),
ElevatedButton.icon(onPressed: (){}, icon: Icon(Icons.navigate_next),label: Text(' '),
style: ButtonStyle(
backgroundColor: MaterialStateProperty.all(Colors.grey),
),
),
],
),
Row(),
],
),
),
),
);
}
use the Row widget properties for laying out its childrens
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [....]
)
the official docs are helpful in that matter
https://api.flutter.dev/flutter/widgets/Row-class.html
sidenote: if you are not planning to use any of the first container() properties then its better to get rid of it
There are 4 options u can use depending on what you want
If u want it below new u can use Column instead of Row .
If u want to put some space next to new u can use SizedBox(width:X) between the Text and the elevated button.
You can use mainAxisAlignment or crossAxisAlignment inside the row or column to customize the position
you can find examples about them here https://docs.flutter.dev/development/ui/layout
you can use margin or padding on elevated button to customize its own position
In this simple implementation code I added some PopupMenuButton items into AppBar actions argument and now I want to styling PopupMenuDivider color which that have default color.
You can do this very easily using the Theme class, using which you can change the icon color, text color and PopupMenuDivider color.
Again, you can easily do this on Divider at PopupMenuItem using PopupMenuDivider.
appBar: AppBar(
title: Text("PopUpMenu Flutter"),
centerTitle: true,
actions: [
Theme(
data: Theme.of(context).copyWith(
dividerTheme: DividerThemeData(
color: Colors.black,
),
iconTheme: IconThemeData(color: Colors.white),
textTheme: TextTheme().apply(bodyColor: Colors.white),
),
child: PopupMenuButton<int>(
color: Colors.indigo,
//onSelected: (item) => onSelected(context, item),
itemBuilder: (context) => [
PopupMenuItem<int>(
value: 0,
child: Text('Settings'),
),
PopupMenuDivider(),
PopupMenuItem<int>(
value: 1,
child: Text('Share'),
),
PopupMenuDivider(),
PopupMenuItem<int>(
value: 2,
child: Row(
children: [
Icon(Icons.logout),
const SizedBox(width: 8),
Text('Sign Out'),
],
),
),
],
),
),
],
),
You can use PopupMenuItem child and assign Column like
PopupMenuItem<WhyFarther>(
value: WhyFarther.harder,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('Working a lot harder'),
Divider(
color: Colors.grey,
)
],
),
),
