I have a somewhat complicated widget tree and can't figure this out. I've tried wrapping the Scaffold body in a SingleChildScrollView but for some reason it just makes the Container shrink and does not scroll. Here is the build function code:
return Stack(
children: [
Scaffold(
resizeToAvoidBottomInset: false,
body: Stack(
children: [
background(),
Padding(
padding: const EdgeInsets.only(top: 55),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset('assets/logo.png', height: 100),
const SizedBox(width: 5),
const Text('GLOBE',
style: TextStyle(
fontSize: 40,
fontWeight: FontWeight.bold,
color: Color(0xFF7FCCDC)))
],
),
),
Padding(
padding: const EdgeInsets.only(
top: 175, left: 35, right: 35, bottom: 50),
child: Container(
decoration: BoxDecoration(
color: const Color(0xFFFCFBF4).withOpacity(0.5),
borderRadius: BorderRadius.circular(20),
),
child: Column(
mainAxisSize: MainAxisSize.max,
children: [
const SizedBox(height: 20),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: const [
Text('Welcome!',
style: TextStyle(
fontSize: 30, color: Color(0xFF6B6FAB))),
],
),
loginForm()
],
),
),
),
],
),
),
if (_isLoading)
const Opacity(
opacity: 0.8,
child: ModalBarrier(dismissible: false, color: Colors.black),
),
if (_isLoading)
const Center(
child: CircularProgressIndicator(color: Color(0xFFb1bbd8)),
),
],
);
Return a scaffold and add a sized box of height and width same as device. As a body use stack. Then in children add the next stack.
return Scaffold(
resizeToAvoidBottomInset: false,
body: SizedBox(
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
child: Stack(
children: [
background(),
SizedBox(
height:MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
child: SingleChildScrollView(
child: Column(
mainAxisSize : MainAxisSize.min,
children:[
Padding(
padding: const EdgeInsets.only(top: 55),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset('assets/logo.png', height: 100),
const SizedBox(width: 5),
const Text('GLOBE',
style: TextStyle(
fontSize: 40,
fontWeight: FontWeight.bold,
color: Color(0xFF7FCCDC)))
],
),
),
Padding(
padding: const EdgeInsets.only(
top: 100, left: 35, right: 35, bottom: 50),
child: Container(
decoration: BoxDecoration(
color: const Color(0xFFFCFBF4).withOpacity(0.5),
borderRadius: BorderRadius.circular(20),
),
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
const SizedBox(height: 20),
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: const [
Text('Welcome!',
style: TextStyle(
fontSize: 30, color: Color(0xFF6B6FAB))),
],
),
loginForm()
],
),
),
),
]
)
)
if (_isLoading)
const Opacity(
opacity: 0.8,
child: ModalBarrier(dismissible: false, color: Colors.black),
),
if (_isLoading)
const Center(
child: CircularProgressIndicator(color: Color(0xFFb1bbd8)),
),
]
)
)
)
TextField has a property called scrollPadding.
scrollPadding: EdgeInsets.only(bottom: 40)
By default it is set to EdgeInsets.all(20.0)
I have 3 container in a column i need to show first 2 container in middle and the 3rd in last on the screen
Something like this
my code is this
return Container(
child: Column(
children: <Widget>[
Container(
width: stackWidth * 0.75,
child: Image.asset('assets/logo.png')),
Container(
color: Color(0xffff4b4b),
child: Padding(
padding: EdgeInsets.all(5),
child: Text(
'Only for LunchBox management',
style: TextStyle(color: Colors.white, fontSize: 18),
)),
),
Container(
child: Padding(
padding: EdgeInsets.all(5),
child: Text(
'Powered by LunchBox KSA',
style: TextStyle(color: Colors.white, fontSize: 18),
)),
)
],
),
);
Its showing in column but i need to show first 2 container of column in middle and third in last
You can do the following:
return Container(
child: Column(
children: <Widget>[
const Spacer(), // <---- New
Container(
width: stackWidth * 0.75,
child: Image.asset('assets/logo.png')),
Container(
color: Color(0xffff4b4b),
child: Padding(
padding: EdgeInsets.all(5),
child: Text(
'Only for LunchBox management',
style: TextStyle(color: Colors.white, fontSize: 18),
)),
),
const Spacer(), // <---- New
Container(
child: Padding(
padding: EdgeInsets.all(5),
child: Text(
'Powered by LunchBox KSA',
style: TextStyle(color: Colors.white, fontSize: 18),
)),
)
],
),
);
Please use this!
return Scaffold(
backgroundColor: Colors.black,
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
color: Colors.white,
width: MediaQuery.of(context).size.width * 0.75,
height: 80,
alignment: Alignment.center,
child: Text(
"YOUR LOGO",
style: Theme.of(context).textTheme.headline6,
),
),
SizedBox(height: 10),
Container(
color: Color(0xffff4b4b),
child: Padding(
padding: EdgeInsets.all(5),
child: Text(
'Only for LunchBox management',
style: TextStyle(color: Colors.white, fontSize: 18),
)),
),
],
),
),
bottomNavigationBar: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
child: Padding(
padding: EdgeInsets.all(20),
child: Text(
'Powered by LunchBox KSA',
style: TextStyle(color: Colors.white, fontSize: 18),
)),
),
],
),
);

In my flutter app, I want to have a card and four boxes aligned horizontally with equal width and height inside it. Code follows ;
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Container(
padding: EdgeInsets.fromLTRB(20,10,10,0),
height: 220,
width: double.maxFinite,
child: Card(
elevation: 5,
child: Column(
children: <Widget>[
Row(
children: <Widget>[
Expanded(
child: Container(
height:25,
color:Color(0xff6898F7),
child: Text('Online Pharmacy',
style:TextStyle(color: Color(0xffffffff)))
)
)
],
),
Row(
children: <Widget>[
Expanded(
flex: 1,
child: Container(
height: 150,
padding: EdgeInsets.only(top:40),
color: Colors.red,
child: Column(
children: <Widget>[
Image.asset("images/medicine.jpg"),
Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding:EdgeInsets.only(top:25),
child:Flexible(
child:Text('Medicine', style: TextStyle(color: Colors.white)),
),
),
],
),
),
],
)
),
),
],
),
],
),
The reason I used Flexible is that I wanted the text to be wrapped in multiple lines where necessary.
But I get this error :
════════ Exception caught by widgets library ═══════════════════════════════════════════════════════
The following assertion was thrown building Container(padding: EdgeInsets(0.0, 40.0, 0.0, 0.0), bg: BoxDecoration(color: MaterialColor(primary value: Color(0xfff44336))), constraints: BoxConstraints(0.0<=w<=Infinity, h=150.0)):
Incorrect use of ParentDataWidget.
Flexible widgets must be placed directly inside Flex widgets.
Flexible(no depth, flex: 1, dirty) has a Flex ancestor, but there are other widgets between them:
- Padding(padding: EdgeInsets(0.0, 25.0, 0.0, 0.0))
These widgets cannot come between a Flexible and its Flex.
The ownership chain for the parent of the offending Flexible was:
Padding ← Row ← Center ← Column ← Padding ← DecoratedBox ← ConstrainedBox ← Container ← Expanded ← Row ← ⋯
So how can I wrap the text properly ? Without the wrapping issue, code works well.
EDIT:
My intended layout seems to be like the image below :
Edit2:
Let me give you a more precise idea about the layout:
Edit3:
After getting a solution ( see here ) in chat room from pskink , I had the following layout. See that the red marked part does not get the text aligned in a centered fashion. How to align text in a centered way ?
try textAlign: TextAlign.center, inside text Widget
Please try this...

That my approach to what you need:
UI Layout
If the purple area is inside an Expanded widget, how would I go about to position the button? I've implemented that UI by setting a fixed height to the purple container but haven't been able to understand how to achieve the same effect if the height is variable, depending on the content.
I was able to get close by using Stack and Positioned widgets but then the button is not really clickable. If anyone can give me a general idea on how to achieve the desired goal I would be thankful.
Here's my attempt (demo case)
#override

Explaining what I described in the comments:
You can use the FractionalTranslation widget to shift your FAB half way down.
FractionalTranslation(translation: Offset(0, .5), child: FloatingActionButton(...))
This requires you to have it positioned at the bottom of the purple area (referring to your screenshot) beforehand, but I assume that you have that figured out.
