How do I wrap the text inside the button, I have used the overflow method in the text widget but it doesn't work. The output I got is this:
this is my code:
Widget build(BuildContext context) {
return TextButton(
onPressed: () {
_awaitValueBottomDrawer(context);
},
style: TextButton.styleFrom(
fixedSize: const Size(200, 120),
primary: Colors.white,
textStyle:TextStyle(
fontSize: 16,
),
shape: RoundedRectangleBorder(
side: BorderSide(color: Colors.transparent)
),
),
child: Row(
children: [
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text('Your Starting Location',style: TextStyle(fontWeight: FontWeight.bold)),
Text(address,overflow: TextOverflow.fade)
],
),
Padding(
padding: const EdgeInsets.all(5.0),
child: Icon(Icons.arrow_drop_down,color: Colors.white,),
)
],
),
);
}
please help
You need to wrap Column widget with Expanded to handle text overflow error set with maxLines property value 1
Widget build(BuildContext context) {
return TextButton(
onPressed: () {
_awaitValueBottomDrawer(context);
},
style: TextButton.styleFrom(
foregroundColor: Colors.white,
fixedSize: const Size(200, 120),
textStyle: const TextStyle(
fontSize: 16,
),
shape: const RoundedRectangleBorder(
side: BorderSide(color: Colors.transparent)),
),
child: Row(
children: [
Expanded(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text(
'Your Starting Location',
style: TextStyle(fontWeight: FontWeight.bold),
maxLines: 1,
),
Text(
address,
overflow: TextOverflow.fade,
// overflow: TextOverflow.ellipsis
maxLines: 1,
)
],
),
),
const Padding(
padding: EdgeInsets.all(5.0),
child: Icon(
Icons.arrow_drop_down,
color: Colors.white,
),
)
],
),
);
}
Ouput: with TextOverflow.fade
Ouput: with TextOverflow.ellipsis
I am having trouble issues aligning my icon buttons to the middle of the card. As you can see in the picture, the icon buttons are on top attached to the top of the card.
How do I make it meet at the half size of the card? Any suggestions? (I want the buttons to be located at the middle of the card)
Tried: I tried putting padding or wrap my Row widget with a center, but it doesn't work.

Try below code and set mainAxisAlignment: MainAxisAlignment.center, to every Column widget. Refer layout and Align
Container(
height: 150.0,
width: MediaQuery.of(context).size.width,
child: Card(
color: Colors.white,
elevation: 8.0,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
IconButton(
onPressed: () {},
icon: Icon(Icons.sticky_note_2),
iconSize: 35,
color: Colors.lightBlue),
Text(
"Notes",
style: TextStyle(
color: Colors.black,
fontSize: 15,
),
),
],
),
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
IconButton(
onPressed: () {},
icon: Icon(Icons.quiz),
iconSize: 35,

What is the issue?
You are using center alignment in the row but not inside the column. Now column is taking the height of entire row but the children of the column is not aligned center.
Solution:
Try adding mainAxisAlignment: MainAxisAlignment.center in each of your column
Present Code:
Row
mainAxisAlignment:MainAxisAlignment.center
|_Column
|_Column
|_Column
Required Code:
Row
mainAxisAlignment:MainAxisAlignment.center
|_Column
mainAxisAlignment:MainAxisAlignment.center 👈 Add these to every column
|_Column
mainAxisAlignment:MainAxisAlignment.center
|_Column
mainAxisAlignment:MainAxisAlignment.center
For the complete code refer : #Ravindra's answer
Replace your "Row" widget with the following code, this will solve your issue.
Solution : Give your Column center alignment
mainAxisAlignment: MainAxisAlignment.center
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
IconButton(
onPressed: () {},
icon: const Icon(Icons.sticky_note_2),
iconSize: 35,
color: Colors.lightBlue),
const Text(
"Notes",
style: TextStyle(
color: Colors.black,
fontSize: 15,
),
),
],
),
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
IconButton(
onPressed: () {
// Navigator.push(
// context,
// MaterialPageRoute(
// builder: (context) => QuizRoute()),
// );
},
icon: const Icon(Icons.quiz),
iconSize: 35,
),
const Text(
"Quizzes",
style: TextStyle(
color: Colors.black,
fontSize: 15,
),
),
],
),
Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
IconButton(

the question is exactly same as this post
but I did not find an answer from the post.
my goal is to set the title widget in the center
and other two buttons on the right side.
the solutions in the link all put the title widget slightly on the left side.
does anyone know how to do this without using Stack? I'm afraid of the title widget being over the button widgets when the title gets too long.
the code:
SizedBox(
height: 40,
width: MediaQuery.of(context).size.width,
child: Row(
children: [
const SizedBox(width: 17),
Text(
'TITLE',
style: const TextStyle(
color: Colors.white, fontSize: 30, fontWeight: FontWeight.w500),
),
Spacer(),
Row(
children: [
GestureDetector(
onTap: (){null;},
child: SizedBox(
child: Icon(Icons.wallet_membership, color: Colors.white),
),
),
const SizedBox(width: 17),
GestureDetector(
onTap: (){Get.toNamed('/wallet_setting');},
child: const SizedBox(
child: Icon(Icons.settings, color: Colors.white),
),
),
]
)
]
),
)
Try this One
Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Expanded(
child: Container(
child: Center(
child: Text(
'TITLE',
style: const TextStyle(color: Colors.white, fontSize: 30, fontWeight: FontWeight.w500),
),
)
)
),
Align(
alignment: Alignment.centerRight,
child: Row(
children: [
GestureDetector(
onTap: (){null;},
child: SizedBox(
child: Icon(Icons.wallet_membership, color: Colors.white),
),
),
const SizedBox(width: 17),
GestureDetector(
onTap: (){Get.toNamed('/wallet_setting');},
child: const SizedBox(
child: Icon(Icons.settings, color: Colors.white),
),
),
]
)
)
],
)
OutPut:
i think you should wrap it with centre
Try this approach:
first make widget from your right widgets:
Widget _rightIcons() {
return Row(children: [
GestureDetector(
onTap: () {
null;
},
child: SizedBox(
child: Icon(Icons.wallet_membership, color: Colors.white),
),
),
const SizedBox(width: 17),
GestureDetector(
onTap: () {
Get.toNamed('/wallet_setting');
},
child: const SizedBox(
child: Icon(Icons.settings, color: Colors.white),
),
),
]);
}
then build your header like this:
Row(
children: [
_rightIcons(),
Expanded(
child: Center(
child: Text(
'TITLE',
style: const TextStyle(
color: Colors.white,
fontSize: 30,
fontWeight: FontWeight.w500),
),
),
),
Opacity(
opacity: 0,
child: _rightIcons(),
)
],
),
You can use centerTitle:true on Appbar
appBar: AppBar(
centerTitle: true,
title: Text("title"),
actions: [
Another way
Container(
color: Colors.purple,
height: 40 * 2,
width: MediaQuery.of(context).size.width,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
IconButton(onPressed: () {}, icon: Icon(Icons.navigate_before)),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(
flex: 1,
child: SizedBox(),
),
Expanded(
flex: 4,
child: Text(
'TITLE',
textAlign: TextAlign.center,
style: const TextStyle(
color: Colors.white,
fontSize: 30,
fontWeight: FontWeight.w500),
),
),
Expanded(
flex: 1,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
GestureDetector(
child: Icon(Icons.wallet_membership,
color: Colors.white),
),
const SizedBox(width: 17),
GestureDetector(
onTap: () {},
child: const SizedBox(
child:
Icon(Icons.settings, color: Colors.white),
),
),
]),
),
)
],
),
],
),
)
Preferable solution:
You can implements PreferredSizeWidget to create custom Appbar. Play with color and other decoration.
class MyAppBar extends StatelessWidget implements PreferredSizeWidget {
const MyAppBar({super.key});
#override
Widget build(BuildContext context) {
return Stack(
children: [
Align(
alignment: Alignment.bottomCenter,
child: Text("title"),
),
Align(
alignment: Alignment.bottomRight,
child: Row(
mainAxisSize: MainAxisSize.min,
children: [
IconButton(
//you can use callback method to get onpressed
onPressed: () {},
icon: Icon(Icons.settings),
),
IconButton(
onPressed: () {},
icon: Icon(Icons.settings),
),
],
),
)
],
);
}
#override
Size get preferredSize => const Size.fromHeight(kToolbarHeight * 2);
}
And use like appBar: MyAppBar(),
Widget build(BuildContext context) {
return Scaffold(
body: SingleChildScrollView(
child: Column(
children: [
Container(
color:Colors.blueGrey.shade900,
width: double.infinity,
height: MediaQuery.of(context).size.height * 0.15,
child: Column(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Text("Available Balance ₹ 10050", style: TextStyle(
color: Colors.white,
fontSize: 18,
),),
],),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
RaisedButton(onPressed: () {}, color: Colors.teal, child: Text("Recharge", style: TextStyle(
color: Colors.white
),),),
RaisedButton(onPressed: () {}, color: Colors.teal, child: Text("Read Rule", style: TextStyle(
color: Colors.white
),),),
Icon(Icons.refresh_rounded, color: Colors.white,)
],),
),
SizedBox(
height: 5,
),
// I need to insert the tabBarHere
],
),
),
],
),
),
);
I have created the widget from flutter but i am not able to display the TabBar after this Widget. I have seen the basic method to create the tabs using DefaultTabController() but it is working when we are using in the bottom of the appbar
You can use a NestedScrollView:
Scaffold(
body: SafeArea(
child: DefaultTabController(
length: 2,
child: NestedScrollView(
headerSliverBuilder: (BuildContext context, bool innerBoxScrolled) {
return <Widget>[
SliverToBoxAdapter(
child: Container(
color: Colors.blueGrey.shade900,
width: double.infinity,
height: MediaQuery.of(context).size.height * 0.15,
child: Column(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Text(
"Available Balance ₹ 10050",
style: TextStyle(
color: Colors.white,
fontSize: 18,
),
),
],
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
RaisedButton(
onPressed: () {},
color: Colors.teal,
child: Text(
"Recharge",
style: TextStyle(color: Colors.white),
),
),
RaisedButton(
onPressed: () {},
color: Colors.teal,
child: Text(
"Read Rule",
style: TextStyle(color: Colors.white),
),
),
Icon(
Icons.refresh,
color: Colors.white,
)
],
),
),
SizedBox(
height: 5,
),
],
),
),
),
SliverToBoxAdapter(
child: Container(
color: Colors.blueGrey.shade900,
child: TabBar(
tabs: <Widget>[
Padding(
padding: const EdgeInsets.symmetric(vertical: 10.0),
child: Icon(Icons.card_giftcard),
),
Padding(
padding: const EdgeInsets.symmetric(vertical: 10.0),
child: Icon(Icons.store),
),
],
),
),
),
];
},
body: Column(
children: <Widget>[
Flexible(
child: TabBarView(
children: [
Center(child: Text('tab 1')),
Center(child: Text('tab 2')),
],
),
),
],
),
),
),
)
)
Result:
you can use bottomNavigationBar
class _MyHomePageState extends State<MyHomePage> {
var selectedIndex = 0;
void onItemTapped(int index) {
setState(() {
selectedIndex = index;
});
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("data"),
backgroundColor: Colors.blueGrey.shade900,
actions: <Widget>[Icon(Icons.notifications)],
),
drawer: Drawer(),
bottomNavigationBar: BottomNavigationBar(
backgroundColor: Colors.amber,
elevation: 12.0,
type: BottomNavigationBarType.shifting,
items: <BottomNavigationBarItem>[
BottomNavigationBarItem(icon: Icon(Icons.store), title: Text('Home')),
BottomNavigationBarItem(
icon: Icon(Icons.warning), title: Text('Warning')),
],
showUnselectedLabels: true,
currentIndex: selectedIndex,
unselectedItemColor: Colors.white,
fixedColor: Colors.teal,
onTap: onItemTapped,
),
body: SingleChildScrollView(
child: Column(
children: [
Container(
color: Colors.blueGrey.shade900,
width: double.infinity,
height: MediaQuery.of(context).size.height * 0.15,
child: Column(
children: [
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Text(
"Available Balance ₹ 10050",
style: TextStyle(
color: Colors.white,
fontSize: 18,
),
),
],
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
RaisedButton(
onPressed: () {},
color: Colors.teal,
child: Text(
"Recharge",
style: TextStyle(color: Colors.white),
),
),
RaisedButton(
onPressed: () {},
color: Colors.teal,
child: Text(
"Read Rule",
style: TextStyle(color: Colors.white),
),
),
Icon(
Icons.refresh,

i am having problems trying to align my widgets. the left side is aligning correctly but the right side is off a little bit.
here is my code
this is the code for the card view
ListView itemList(List<IncomeData> items, AppDatabase database, BuildContext context) {
return ListView(
children: items.map((IncomeData income) {
return Container(
child: Padding(
padding: const EdgeInsets.fromLTRB(15.0, 5.0, 15.0,5.0),
child: new Card( //listView(income),
child: Padding(
padding: const EdgeInsets.fromLTRB(20.0, 0.0, 20.0,0.0),
child: new Column(
children: <Widget>[
listView(income),
new ButtonBar(
children: <Widget>[
new RaisedButton.icon(
label: const Text('Edit'),
icon: Icon(Icons.edit,),
color: colorPrimary,
onPressed: () {
_navigateAndDisplaySelection(context, income);
/* Navigator.push(context,
MaterialPageRoute(builder: (context) => AddEditIncomeForm(incomeData: income)));*/
},
),
new RaisedButton.icon(
label: const Text('Delete'),
icon: Icon(Icons.delete),
color: colorPrimary,
onPressed: () {
//database.deleteEntry(income);
//deleteConfirmation(income, database);
showDialog(
context: context,
builder: (context) {
return CheckBoxAlertDialog(transactionType: delete, data: income, database: database,);
}
);
},
),
],

}).toList(),

}
this is the code for the content of the card view

if you take a look at the pic attached, the buttons and the top switch is not align properly to the number $68.00. see the red line i drawed. the switch on top is off to the left by a few spaces and also the buttons are the bottom are not align exactly to $68.00
am i doing something wrong that the widgets are not aligning to the red line as $68.00 is? how can i change my code to properly align all the widgets on the right side? thanks in advance
For ButtonBar it's buttonPadding parameter. Just be sure not to use any horizontal padding with it (right or left), since it will split it between the buttons. You will have to add a left padding for the buttons inside the ButtonBar.
I've attached an example for it and for the Switch widget, which doesn't have any properties to modify this behavior, but you can always use Transform.translate to overcome this.
Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
Transform.translate(
offset: Offset(10.0, 0.0),
child: Switch(
value: true,
onChanged: (value) {},
activeTrackColor: Colors.lightGreenAccent,
activeColor: Colors.green,
),
),
],
),
ButtonBar(
buttonPadding: EdgeInsets.zero,
children: <Widget>[
RaisedButton.icon(
label: const Text('Edit'),
icon: Icon(
Icons.edit,
),
color: Colors.blue,
onPressed: () {},
),
Padding(
padding: const EdgeInsets.only(left: 10.0),
child: RaisedButton.icon(
label: const Text('Delete'),
icon: Icon(Icons.delete),
color: Colors.blue,
onPressed: () {},
),
),
],
),
