I have a card that contains row of items (text and checkbox widgets). The problem is that the card can only fill up limited space each row, but it isn't going to the next line in the row. I tried using the wrap widget but it had no effect. I keep getting this:
As you can see it is not wrapping to the next but trying to fit everything in that one line. Here is my code:
Widget _buildCategories() {
return Card(
margin: const EdgeInsets.only(top: 20.0),
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
children: <Widget>[
Text(
'Categories',
style: TextStyle(fontFamily: 'MonteSerrat', fontSize: 16.0),
),
Wrap(
children: <Widget>[
Row(
children: <Widget>[
_checkBox('Gaming'),
_checkBox('Sports'),
_checkBox('Casual'),
_checkBox('21 +'),
_checkBox('Adult'),
_checkBox('Food'),
_checkBox('Club'),
_checkBox('Activities'),
_checkBox('Shopping'),
],
)
],
)
],
),
));
}
Widget _checkBox(String category) {
return Expanded(
child: Column(
children: <Widget>[
Text(
'$category',
textAlign: TextAlign.center,
style: TextStyle(fontFamily: 'MonteSerrat'),
),
Checkbox(
value: false,
onChanged: (value) {
// We will update the value to the firebase data here
print('updated value to: $value');
},
)
],
));
}
A Wrap lays out each child and attempts to place the child adjacent to the previous child in the main axis, given by direction, leaving spacing space in between. If there is not enough space to fit the child, Wrap creates a new run adjacent to the existing children in the cross axis.
Steps to add border to container in Flutter:Step 1: Go to the Container in which you want to add a border. Step 2: Add the decoration parameter and assign the BoxDecoration class. Inside the BoxDecoration add the parameter border and set it to Border. all().
I fixed your code with the following changes:
Removed Row
widget inside Wrap
.
Removed Expanded
widget.
Add the property maxLines
to your Text
widget.
Widget _buildCategories() {
return Card(
margin: const EdgeInsets.only(top: 20.0),
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
children: <Widget>[
Text(
'Categories',
style: TextStyle(fontFamily: 'MonteSerrat', fontSize: 16.0),
),
Wrap(
children: <Widget>[
_checkBox('Gaming'),
_checkBox('Sports'),
_checkBox('Casual'),
_checkBox('21 +'),
_checkBox('Adult'),
_checkBox('Food'),
_checkBox('Club'),
_checkBox('Activities'),
_checkBox('Shopping')
],
)
],
),
));
}
Widget _checkBox(String category) {
return Column(
children: <Widget>[
Text(
'$category',
maxLines: 1,
textAlign: TextAlign.center,
style: TextStyle(fontFamily: 'MonteSerrat'),
),
Checkbox(
value: false,
onChanged: (value) {
// We will update the value to the firebase data here
print('updated value to: $value');
},
)
],
);
}
}
Also you can add the properties runSpacing
and spacing
to your Wrap
widget to give more space between your items in horizontal and vertical.
Wrap(
runSpacing: 5.0,
spacing: 5.0,
