I am getting half of my data loaded in the card, remaining content is not displayed. I tried to place height for the container inside the card, but that is not working.
I need help to sort this out. Any help is appreciated.
Thanks in advance.
Removing the itemExtent property of listView builder solved the issue.

I'm trying to implement a UI design, something like this:
And that's what I've achieved so far:
I got stuck in the stage of filling the screen with boxes, I tried to implement this in multiple ways(expanded, containers etc), but the result didn't satisfy me.
How do i implement this?
And I also have another problem, when i create the drawer it work(i can scroll the screen to the right and the drawer navigation screen appears), But i can't see the drawer icon.
By the way, if you have suggestions for improving the code or things I could write better i'll be glad to hear that
My code:
class Sample extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
drawer: Drawer(),
body: Column(
children: <Widget>[
Stack(
children: <Widget>[
Container(
height: MediaQuery.of(context).size.height / 2,
width: double.infinity,
color: Color.fromRGBO(50, 50, 205, 1),
),
Opacity(
child: Image.network(
'https://cdn.pixabay.com/photo/2015/04/23/21/36/auto-736794__340.jpg',
//half of the screen
height: MediaQuery.of(context).size.height / 2,
fit: BoxFit.cover,
),
opacity: 0.3,
),
SafeArea(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(bottom: 58.0),
child: Text(
'Parking App',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
),
],
),
),
],
),
],
),
);
}
}
There might be better ways to achieve this, but here's the solution with rows and columns:
import 'package:flutter/material.dart';
class SamplePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
final screenHeight = MediaQuery.of(context).size.height;
return Scaffold(
body: Column(
children: <Widget>[
Image.network(
"http://i63.tinypic.com/16p2xu.jpg",
fit: BoxFit.cover,
height: screenHeight / 2,
),
Expanded(
child: Row(
children: <Widget>[
Expanded(
child: Column(
children: <Widget>[
Expanded(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.account_balance),
SizedBox(height: 10),
Text("My Stats"),
],
),
),
Expanded(
child: Container(
color: Colors.indigo,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Icon(Icons.accessibility, color: Colors.white),
SizedBox(height: 10),
Center(
child: Text(
"Component",
style: TextStyle(color: Colors.white),
),
)
],
),
),
),
],
),
),
Expanded(
child: Container(
color: Colors.cyanAccent,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.access_alarm),
SizedBox(height: 20),
Text("Workout"),
],
),
),
),
],
),
),
],
),
);
}
}
Result:
you can achieve similar layout using stack. i demonstrated as below.
Note: make sure that you are using full screen with content otherwise black screen will be there.
class Sample extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Stack(
children: <Widget>[
Column(
children: <Widget>[
Container(
height: MediaQuery.of(context).size.height / 2,
width: double.infinity,
decoration: BoxDecoration(
color: Color.fromRGBO(50, 50, 205, 0.3),
image: DecorationImage(
image: NetworkImage(
'https://cdn.pixabay.com/photo/2015/04/23/21/36/auto-736794__340.jpg',
),
fit: BoxFit.cover,
),
),
),
],
),
Scaffold(
backgroundColor: Colors.transparent,
drawer: Drawer(),
appBar: AppBar(
backgroundColor: Colors.transparent,
elevation: 0.0,
title: new Text("Demo"),
centerTitle: true,
),
body: Column(
children: <Widget>[
Expanded(
child: Center(
child: new Container(
decoration: BoxDecoration(
color: Colors.red
),
child: new Text("book"),
),
),
)
],
),
),
],
);
}
}
Here's a mockup of the dialog I'm trying to create in Flutter:
Here's what I have so far:
I'm unable to position my two button's with rounded bottom corners at the bottom of the dialog so that it looks like in the mockup.
I was able to make those buttons fit within the Dialog width, without the stack, but then it would be positioned at the top.
Here's the code for the dialog:
SimpleDialog carDialog = SimpleDialog(
contentPadding: EdgeInsets.all(0),
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(6)),
children: <Widget>[
Container(
height: 400,
child: Stack(
children: <Widget>[
Positioned(
bottom: 0,
child: IntrinsicWidth(
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Expanded(
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(
bottomLeft: Radius.circular(6)),
color: Colors.lightBlueAccent,
),
height: 45,
child: Center(
child: Text(
allTranslations.text('wait_enroute').toUpperCase(),
textAlign: TextAlign.center,
style: Fonts.appFont(context,
bold: true, color: Colors.white),
),
),
),
),
Expanded(
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(
bottomRight: Radius.circular(6)),
color: AppColors.action_button,
),
height: 45,
child: Center(
child: Padding(
padding:
const EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
allTranslations.text('new_order').toUpperCase(),
textAlign: TextAlign.center,
style: Fonts.appFont(context,
bold: true, color: Colors.white),
),
),
),
),
),
],
),
),
),
],
),
),
],
);
showDialog(context: context, builder: (context) => carDialog);
I have found a working solution. It does not require the Stack widget, everything can be nested within a Column like so:
SimpleDialog carDialog = SimpleDialog(
contentPadding: EdgeInsets.all(0),
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(6)),
children: <Widget>[
Column(
children: <Widget>[
SizedBox(
height: 400,
),
Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Expanded(
child: InkWell(
child: Container(
decoration: BoxDecoration(
borderRadius:
BorderRadius.only(bottomLeft: Radius.circular(6)),
color: Colors.lightBlueAccent,
),
height: 45,
child: Center(
child: Text(
allTranslations.text('wait_enroute').toUpperCase(),
textAlign: TextAlign.center,
style: Fonts.appFont(context,
bold: true, color: Colors.white),
),
),
),
),
),
Expanded(
child: Container(
decoration: BoxDecoration(
borderRadius:
BorderRadius.only(bottomRight: Radius.circular(6)),
color: AppColors.action_button,
),
height: 45,
child: Center(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
allTranslations.text('new_order').toUpperCase(),
textAlign: TextAlign.center,
style: Fonts.appFont(context,
bold: true, color: Colors.white),
),
),
),
),
),
],
),
],
),
],
);
showDialog(context: context, builder: (context) => carDialog);
The result:
You can try this replacing with Row
LayoutBuilder(
builder:(BuildContext context, BoxConstraints constraints){
return Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
SizedBox(
width : constraints.maxWidth/2
child:Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(
bottomLeft: Radius.circular(6)),
color: Colors.lightBlueAccent,
),
height: 45,
child: Center(
child: Text(
allTranslations.text('wait_enroute').toUpperCase(),
textAlign: TextAlign.center,
style: Fonts.appFont(context,
bold: true, color: Colors.white),
),
),
),
),
SizedBox(
width : constraints.maxWidth/2
child:Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(
bottomRight: Radius.circular(6)),
color: AppColors.action_button,
),
height: 45,
child: Center(
child: Padding(
padding:
const EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
allTranslations.text('new_order').toUpperCase(),
textAlign: TextAlign.center,
style: Fonts.appFont(context,
bold: true, color: Colors.white),
),
),
),
),
),
],
);
}
),

i need help to make card stack with parent like
Result I want
i already try with using stack but the result card parent card overlaping the first card.
I know about little bit on Expanded tag but Expanded expand view to both direction, i dont know how to do it. Help me if you know, Thanks in Advance.
You don't need Stack to get that view - it can be done using Column & Material widget.
return Scaffold(
body: new Container(
decoration: new BoxDecoration(color: Colors.blue),
child: new Center(
child: MergeSemantics(
child: Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Card(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Material(
elevation: 24.0,
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Text("Sign Up Here"),
),
),
Padding(
padding: EdgeInsets.fromLTRB(20, 10.0, 20.0, 20.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
TextField(
decoration: InputDecoration(
labelText: "Email",
hintText: "example#mail.com",
),
autofocus: true,
),
TextField(
decoration: InputDecoration(
labelText: "Password",
),
autofocus: true,
),
SizedBox(
width: double.infinity,
// height: double.infinity,
child: new RaisedButton(
color: Colors.blue,
child: Text(
"Sign In",
style: TextStyle(
color: Colors.white,
fontFamily: 'Raleway',
fontSize: 22.0,
),
),
onPressed: () => print('Sign In'),
),
)
],
)),
],
),
),
],
),
),
)),
));
Output:
If you want to resize or alter the card view Then just put Card inside the Container view then adjust your container size.

Just Put Card in Container
Padding(
padding: EdgeInsets.all(20),
child: Container(
height: 50,
width: double.infinity,
child: Card(
child: Align(
alignment: Alignment.centerLeft,
child: Text("Edit Profile")),
),
),
)
Use Material widget that will use as same as card do...and take always a full width and height as same as its parent class...

I think flutter widgets are resized when keyboard pops up, I've resolved this issue by setting value false of resizeToAvoidBottomPadding inside Scaffold. Issue has been resolved but still I am looking for the reason behind this issue.

I am trying to create the below image in to flutter. Trying to follow some examples but unable to get the right mix.
Plan is to connect to firebase in the next stage. So, for now I have to create a single card and then replicate it. But, I am having trouble to get the UI right thru trial and error. Any help looking in to this is much appreciated.
So far below is what I have.
import 'package:flutter/material.dart';
class liberPage extends StatefulWidget {
#override
_liberPage createState() => new _liberPage();
}
class _liberPage extends State<liberPage> {
final ShapeBorder shape;
#override
Widget build(BuildContext context) {
return new Container(
child: new Column(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
new Row(
mainAxisAlignment: MainAxisAlignment.end,
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
new Card(
elevation: 10.0,
shape: shape,
color: Colors.blue,
margin: EdgeInsets.only(top: 20.0),
child: new Column(
children: <Widget>[
new Icon(
Icons.ac_unit,
size: 100.0,
),
new Text(
"Test",
textAlign: TextAlign.left,
),
new Icon(
Icons.menu,
size: 100.0,
),
],
),
),
new Card(
elevation: 10.0,
color: Colors.yellow,
child: new Column(
children: <Widget>[
new Icon(
Icons.ac_unit,
size: 100.0,
),
],
),
)
]
)
]
),
);
}
}
What you need is a GridView with Stack widgets, not nested Rows and Columns. I have created minimal UI that may be of help.
class DishCardExample extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: GridView.count(
shrinkWrap: true,
crossAxisCount: 2,
children: List.generate(
10,

Expanded(
child: Stack(
