I'm trying to personalize what's inside a RaisedButton for my home automation project, in with I add different types of text and icons to the Button. but I'm getting an overflow by 1 pixel for some reason.
ClipRRect(
borderRadius: BorderRadius.circular(10),
child: SizedBox(
width: 90.0,
height: 90.0,
child: RaisedButton(
onPressed: () {},
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Icon(Icons.stay_primary_portrait),
Column(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Padding(
padding: EdgeInsets.only(left: 0),
child: Text('Lock'),
),
Padding(
padding: EdgeInsets.only(left: 0),
child: Text('100%'),
),
],
),
],
),
),
),
),
The app:
The RaisedButton has some default padding. Fix it by removing the default padding.
This would work perfectly, check it out.
ClipRRect(
borderRadius: BorderRadius.circular(10),
child: SizedBox(
width: 90.0,
height: 90.0,
child: RaisedButton(
// remove the default padding the raised button has
padding: EdgeInsets.zero,
onPressed: () {},
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Icon(Icons.stay_primary_portrait),
Column(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Padding(
padding: EdgeInsets.only(left: 0),
child: Text('Lock'),
),
Padding(
padding: EdgeInsets.only(left: 0),
child: Text('100%'),
),
],
),
],
),
),
),
),
The output looks like this

I didn't figure out why you get this result but you can use InkWell + Container instead of RaisedButton:
ClipRRect(
borderRadius: BorderRadius.circular(10),
child: SizedBox(
width: 90.0,
height: 90.0,
child: InkWell(
onTap: () {},
child: Container(
color: Colors.grey,
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Icon(Icons.stay_primary_portrait),
Column(
mainAxisAlignment: MainAxisAlignment.start,
children: <Widget>[
Padding(
padding: EdgeInsets.only(left: 0),
child: Text('Lock'),
),
Padding(
padding: EdgeInsets.only(left: 0),
child: Text('100%'),
),
],
),
],
),
),
),
),
),

I want to show these two buttons click the middle button in the bottom navigation. Already I created the bottom dialog box but it's not working. on click of image button. please help me!
void _bottomSheet() {
Container(
height: 500,
width: double.infinity,
color: Colors.white,
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.end,
children: [
Row(
children: [
Flexible(
flex: 1,
child: Align(
alignment: Alignment.centerRight,
child: FloatingActionButton(
onPressed: () {
// Add your onPressed code here!
},
backgroundColor: Colors.black,
child: const Icon(
MyBottomIcon.barcode,
),
),
),
),
SizedBox(
width: 20,
),
Flexible(
flex: 1,
child: Align(
alignment: Alignment.centerLeft,
child: FloatingActionButton(
onPressed: () {
// Add your onPressed code here!
},
backgroundColor: Colors.black,
child: const Icon(
MyBottomIcon.barcode,
),
),
),
),
],
),
],
),
);
}
Please review my code and correct me when I call this method showing nothing on the screen.
My suggestion is by using floatingActionButton
floatingActionButton: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.end,
children: [
Container(
padding: const EdgeInsets.all(5),
width: 80.0,
height: 80.0,
child: FloatingActionButton(
onPressed: () => showAlertDialog(context), // Call the function from example below
elevation: 7.0,
child: const Icon(
Icons.add,
size: 50,
),
),
),
],
),
floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
Create the showAlertDialog(context) function and suit the Widget as your needs.
showAlertDialog(BuildContext context) {
showDialog(
context: context,
builder: (BuildContext context) {
return Center(
child: Container(
padding: const EdgeInsets.only(top: 380.0),
child: Stack(
clipBehavior: Clip.none,
alignment: Alignment.center,
children: <Widget>[
Container(
width: double.infinity,
height: 800,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15),
color: Colors.transparent),
padding: const EdgeInsets.fromLTRB(20, 50, 20, 20),
child: Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,

Container(

padding: const EdgeInsets.all(5.0),

Padding(

Why does the 1st two work but not the 3rd?? what's the alternative to add vertical divider with height that stretch to the max height of the row?
These 2 works
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
// crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Container(
child: Text('Kicukiro'),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
)
],
)
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
// Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
this does not work
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
Test this and it will work
IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
Container(color:Colors.black, width: 1),
Expanded(
child: Container(
padding: const EdgeInsets.symmetric(horizontal: 10),
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
],
),
),
In the last screenshot please add the Container under an Expanded widget. Use children property under Row widget.
Here is an example code
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 5,
child: Padding(
padding: EdgeInsets.all(10.0),
child: Center(
child: Text(
'This is question',
style: TextStyle(
fontSize: 25.0,
color: Colors.white,
),
),
),
),
),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.green,
child: Text(
'True',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.red,
child: Text(
'False',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
]
The third is true, in fact, its existence in an SingleChildScrollView has created a problem
It is fixed by putting SizedBox in Row and giving it height
The reason for this problem is the size of the height of the container, which is determined by double.infinity and due to its presence in an SingleChildScrollView, it continues indefinitely and an error was created.
SingleChildScrollView(
child: SizedBox(
height: 250,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(child: Container(child: Text("Kicukiro"))),
Container(
width: 1,color: Colors.black,height: double.infinity,
),
Expanded(child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text("Kicukiro"))),
],
),
),
),
I'm new to Flutter and have been trying to clone a screen that requires a scroll architecture.Here is the link of the screen that i'm working on. https://i.stack.imgur.com/1OW2b.pngThe code is as below.PS: Ignore the fields that are incomplete. As soon as I get the scroll view, i'll add the functionalities afterwards.
Scaffold(
body: Column(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(15.0, 40.0, 15.0, 0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,

Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: const <Widget>[
Icon(Icons.menu),
Image(), //Asset image
],
),
Row(
children: <Widget>[
const Icon(Icons.notifications_none),
const SizedBox(width: 27.0),
CircleAvatar(
child: Text("JM"),
),
],
)
],
),
Row(
children: const <Widget>[
Icon(Icons.arrow_back),
SizedBox(width: 20.0),
Text("Public page"),
],
),
const SizedBox(

),
const Text(" Please fill the form following the proper order."),
const SizedBox(height: 10.0),
OverviewWidget(), //Widget with lots of TextFormField
SizedBox(height: 10.0),
DescriptionWidget(), //Widget with lots of TextFormField
],
),
),
Align([enter image description here][1]
alignment: Alignment.bottomCenter,
child: GestureDetector(
onTap: () {
print("Hello");
},
child: Container(
height: 130.0,
width: double.infinity,
alignment: Alignment.center,
decoration: BoxDecoration(
color: Colors.white,
boxShadow: [
BoxShadow(

blurRadius: 10,
spreadRadius: 1,
)
],
),
child: Container(
margin: const EdgeInsets.only(top: 10.0, bottom: 30.0),
decoration: BoxDecoration(

borderRadius: BorderRadius.circular(35),
),
child: const Padding(

vertical: 15.0,
horizontal: 150.0,

child: Text(
"Save",
style: TextStyle(

fontWeight: FontWeight.w600),
),
),
),
),
),
),
],
),
);
So far, i've only created the Overview and Description widgets and i'm already getting RenderFlex overflow error. I tried wrapping the very first Column widget with a SingleChildScrollView widget but it can be noticed that the Save button at the bottom should stay fixed. I tried wrapping the whole widget with Stack widget instead of a Column widget but it didn't help either. I also used ListView widget but got the same results.What shall I do to achieve this view?
I guess you had all the elements but did not quite manage to use them as needed.
Your screen is composed of two important layout:
A stack (containing a button on top of a scrollable widget)
The scrollable widget
The stack has to be a stack, the scrollable can be anything but in your case SingleChildScrollView+Column seems the best choice.
Here is the concrete implementation:
Scaffold(
body: Stack(
children: <Widget>[
Padding(
padding: const EdgeInsets.fromLTRB(15.0, 40.0, 15.0, 0),
child: SingleChildScrollView(
child: Padding(
padding: const EdgeInsets.only(bottom: 100.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Icon(Icons.menu),
Container(
height: 100,
width: 100,
color: Colors.redAccent,
),
//Asset image
],
),
Row(
children: <Widget>[
const Icon(Icons.notifications_none),
const SizedBox(width: 27.0),
CircleAvatar(
child: Text("JM"),
),
],
)
],
),
Row(
children: const <Widget>[
Icon(Icons.arrow_back),
SizedBox(width: 20.0),
Text("Public page"),
],
),
const SizedBox(
height: 20.0,
),
const Text(" Please fill the form following the proper order."),
const SizedBox(height: 10.0),
Container(
height: 400,
color: Colors.blueAccent,
), //Widget with lots of TextFormField
SizedBox(height: 10.0),
Container(
height: 400,
color: Colors.greenAccent,
), //Widget with lots of TextFormField
],
),
),
),
),
Align(
alignment: Alignment.bottomCenter,
child: GestureDetector(
onTap: () {
print("Hello");
},
child: Container(
height: 130.0,
width: double.infinity,
alignment: Alignment.center,
decoration: BoxDecoration(
color: Colors.white,
boxShadow: [
BoxShadow(
color: Colors.grey.shade400,
blurRadius: 10,
spreadRadius: 1,
)
],
),
child: Container(
margin: const EdgeInsets.only(top: 10.0, bottom: 30.0),
decoration: BoxDecoration(
color: Colors.green.shade400,
borderRadius: BorderRadius.circular(35),
),
child: const Padding(
padding: EdgeInsets.symmetric(
vertical: 15.0,
horizontal: 150.0,
),
child: Text(
"Save",
style: TextStyle(
color: Colors.white, fontSize: 17, fontWeight: FontWeight.w600),
),
),
),
),
),
),
],
),
)
Note that you have to put a bottom padding inside the SingleChildScrollView to take into account the button. This is fine in your case since the button has a static height. However if you need something more fancy you might want to check How to create a scroll view with fixed footer with Flutter? as #Csisanyi suggested
Consider wrapping the Column with an Expanded widget
You can also check out this flutter doc. It addresses this common issue in detail.

I am implementing a card where I have rows, I want to add column below rows inside the card in flutter. I am unable to add column at the bottom inside the card.
Column buildWorkshopSection() {
return Column(
children: [
Card(
margin: EdgeInsets.symmetric(horizontal: 20.0, vertical: 5.0),
clipBehavior: Clip.antiAlias,
color: Colors.white,
elevation: 5.0,
child: Padding(
padding:
const EdgeInsets.symmetric(horizontal: 8.0, vertical: 22.0),
child: Row(
children: <Widget>[
Expanded(
child: Column(
children: <Widget>[
SizedBox(
height: 5.0,
),
buildStartTimeWorkshop(),
],
),
),
Expanded(
child: Column(
children: <Widget>[
SizedBox(
height: 5.0,
),
buildCloseTimeWorkshop(),
],
),
),
],
),
),
)
],
);
}
Add submit button like this
Card(
margin:
EdgeInsets.symmetric(horizontal: 20.0, vertical: 5.0),
clipBehavior: Clip.antiAlias,
color: Colors.white,
elevation: 5.0,
child: Padding(
padding: const EdgeInsets.symmetric(
horizontal: 8.0, vertical: 22.0),
child: Column(
children: [
Row(
children: <Widget>[
Expanded(
child: Column(
children: <Widget>[
SizedBox(
height: 5.0,
),
buildStartTimeWorkshop(),
],
),
),
Expanded(
child: Column(
children: <Widget>[
SizedBox(
height: 5.0,
),
buildCloseTimeWorkshop(),
],
),
),
],
),
SizedBox(
height: 20,
),
RaisedButton(
onPressed: () {},
child: Text("Submit"),
)
],
),
),
),
It look like this
I am using Slidable and whenever it is used, the widget below is moved up.
Widget buildItemList(BuildContext context, DocumentSnapshot document) {
return new Container(
child: Card(
elevation: 10.0,
margin: new EdgeInsets.symmetric(horizontal: 10.0, vertical: 10.0),
child: Slidable(
actionPane: SlidableDrawerActionPane(),
//actionExtentRatio: 0.25,
closeOnScroll: false,
secondaryActions: <Widget>[
IconSlideAction(
caption: 'Delete',
color: Colors.red,
icon: Icons.delete,
onTap: (){},
)
],
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
// Unnecessary code was removed
children: <Widget>[
Container(
padding: const EdgeInsets.only(right: 12.0),
child: Row(
children: <Widget>[
Text('0'),
Text('/'),
Text(document['value'].toString())
],)
)
]
),
),
),
);
}
It does not matter where i put Slidable, it always resizes the widget.
Someone able to help?
Thank you!
This will fix the issue
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Expanded(
child: Container(
height: double.maxFinite,
width: double.maxFinite,
padding: const EdgeInsets.only(right: 12.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.end,
children: <Widget>[
Text('0'),
Text('/'),
Text('value'.toString())
],
)),
)
],
),
If you don't need extra functionality you can remove the two rows and simply write something like
child: Container(
alignment: Alignment.centerRight,
padding: const EdgeInsets.only(right: 12.0),
child: Text('0/${document['value'].toString()}'),
),
