I have been getting this message: Right Overflowed by 200 pixels
You can see the code and please help to solve it and make the ow widget a flexible one without changing the alignment
see the image here
I have tried SingleChildScrollView, Wrap but all of them change the alignment to center.
Code:
Row(
children: <Widget>[
Icon(Icons.mail),
Text(
" " + usersData[index]['email'],
style: TextStyle(fontSize: 23),
),
],
),
try to change your Row Widget into Column.
If your Row Widget is like this:
Row(
children: <Widget>[
new Text("..."),
]
)
Change it to :
Column(
crossAxisAlignment: CrossAxisAlignment.start, // for the horizontal alignment
children: <Widget>[
new Text("..."),
]
)

When my Expanded widget has expanded there are 20 items, which cause a vertical overflow issue. How do I get the contents within Expanded widget to scroll? I've tried wrapping the content in a SinglechildScrollView but it still didn't allow scrolling.
Scaffold(
key: key,
appBar: customappbar,
body: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisAlignment: MainAxisAlignment.start,
children: [
ExpansionTile(
title: Text(
"${_getcurrentselection(context)}:",
style: const TextStyle(fontSize: 16),
),
children: <Widget>[
for (Map<String, dynamic> submenuitemdata in subMenuItems)
Padding(
padding: const EdgeInsets.only(bottom:10.0),
child: SubmenuItem(submenuitem: submenuitemdata),
),
Expanded(
child: WebViewWidget(controller: controllerGlobal),
),
],
),
],
),
),
Try putting your widgets inside a ListView which should be inside the Expanded.
I couldn't find a suitable solution sa the Expanded widget below the ExpansionTile widget kept throwing errors no matter what I tried. Instead I placed both inside a Stack, so that the ExpansionTile expands over the top of any other widgets.
Also, minus 2 was a bit harsh
I am facing error in the Text widget which is in Column.
body: Padding(
padding: const EdgeInsets.all(20),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
widget.songModel.displayNameWOExt, <------- here is my text
),
Text(
widget.songModel.artist.toString(),
overflow: TextOverflow.fade,
),
],
),
],
), ), );
This is what happened to me
This is what i need look like
Wrap the Text that is inside a Row widget with an Expanded widget:
Expanded(child: Text(/* Here the text*/),
wrap the text with the container and give a specific size to the container after that use overflow: TextOverflow.fade or any other property of "overflow", because these properties only work when you give a size to textfield but you cant give size to textfield so wrap it with container.
try embedding the Text() widget inside a Expanded() widget expanded documentation
Expanded is a widget that expands a child of a Row, Column, or Flex so that the child fills the available space.
I would like to center the FirstWidget in a row in flutter, not the complete row. The second widget should follow right next to it.
{
return Container(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
FirstWidget(...),
SecondWidget(...), ],
));
}
```
Assuming that the other widgets have the same width, we could use the Spacer widget to fill the space, as per the following code:
Row(
children: [
FirstWidget(),
Spacer(),
CenteredWidget(),
Spacer(),
SecondWidget(),
]
)
Another solution would be to wrap the Row in a Stack and use the power of Positioned to overlay a Widget in the center:
Stack(
alignment: Alignment.center,
children: [
FirstWidget(),
Row(children: _rowChildren),
],
)
How to place a Widget below fixed Centered Widget inside a Container? I am using a GridView to show widgets horizontally. GridView item will have a Text Widget which has to be fixed at the Centered everytime in the screen. I have to place a Text widget below that Centered Widget.
Reference Screenshot:
Adding the build method code of the GridView item I have tried till now. But the Text Widget is not getting centered. The output I am getting. How to fix this part ?
#override
Widget build(BuildContext context) {
return Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
CustomText(
(dayModel?.date?.day ?? "").toString(),
AppTextStyle.Body,
customColor: _getColorBasedOnStyle(
dayModel.style,
),
),
Visibility(
visible: dayModel?.style == CalendarDayStyles.NOT_AVAILABLE,
child: CustomText(
Strings.no_slots_label,
AppTextStyle.SublineForCalendar,
customColor: AppColors.BLACK_20,
),
),
],
);
}
I believe the secret to doing this right is not only in how you build "6", but also in how you build "5" and "7".
E.g. you could build every one of them as column with 3 boxes on top of each other, pseudocode:
Column(
children: [
SizedBox(height: fixedHeight, child: empty)
SizedBox(height: fixedHeight, child: Text("5")) // or "6" or "7"
SizedBox(height: fixedHeihgt, child: empty) // or booking status
]
)
or other way of doing it if we have to avoid using fixedHeight is by using the Expanded Widget inside the Column Widget
Column(
children: [
Expanded(child: Container()),
Expanded(child: Center(child : Text("5"))), // or "6" or "7"
Expanded(child: Center(child : Text("No Slots"))) // or booking status
]
)
If you set crossAxisAlignment of the row to start and then show a column with "no slots" underneath, shouldn't this fix your issue?
You could use the CrossAxisAlignment.center:
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
),
Full snippet code:
#override
Widget build(BuildContext context) {
return Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
CustomText(
(dayModel?.date?.day ?? "").toString(),
AppTextStyle.Body,
customColor: _getColorBasedOnStyle(
dayModel.style,
),
),
Visibility(
visible: dayModel?.style == CalendarDayStyles.NOT_AVAILABLE,
child: CustomText(
Strings.no_slots_label,
AppTextStyle.SublineForCalendar,
customColor: AppColors.BLACK_20,
),
),
],
);
I've tried the following and got the out, but the body went blank.
Is there any way to add a coloumn or a listview inside a bottom navigation bar
Column(
mainAxisAlignment:MainAxisAlignment.end,
children: <Widget>[
Row(
children: <Widget>[
Expanded(
//button1
),
Expanded(
//button2
),
Expanded(
//button3)
),
Row(
children: <Widget>[
Expanded(
//button4
),
Expanded(
//button5)
],
)
],
),
Apart from the issue posed by Expanded widget (as pointed out in the answer by alexandreohara),
Column's mainAxisSize attribute is set to MainAxisSize.max by default. That means the column will try to occupy all the space available (the entire screen height).
Setting Column's mainAxisSize to MainAxisSize.min will wrap the Column widget to occupy the least possible space(vertically) and not span the entire screen.
Following is the way it can be done:
Column(
mainAxisSize: MainAxisSize.min,
children: [...]
);
There's no problem using a Column in a BottomNavigationBar. I think that your problem is wrapping everything in Expanded. It doesn't know the width of the widgets inside, and because of that, it will return blank.
Try to remove those Expanded widgets and try this:
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween
children: [FlatButton(...), FlatButton(...)],
)
