I put an Image in a Stack because I want to have a x-Button in the upper right corner.
But I don't know, how to set the image like this.
It actual looks like this:
This is the code:
list.add(Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
child: Stack(children: [
Flexible(
child:
Image.network("${globals.api}/download/$nextPicture")),
Align(
alignment: const Alignment(0.95, -0.95),
child: IconButton(
icon:
const Icon(Icons.cancel, color: Colors.white, size: 25),
onPressed: () {
deleteSelectedImageRemote(nextPicture);
},
),
)
]),
)
]));
Do you have any suggestions, how to make it look like the Details page?
Thank you very much!
try this
list.add(Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
child: Stack(children: [
Container(
width:200,
height:200,
child:
Image.network("${globals.api}/download/$nextPicture")),
Align(
alignment: const Alignment(0.95, -0.95),
child: IconButton(
icon:
const Icon(Icons.cancel, color: Colors.white, size: 25),
onPressed: () {
deleteSelectedImageRemote(nextPicture);
},
),
)
]),
)
]));
The icon on FloatingActionButton extended is on left, how can i put the icon on right? after the text
floatingActionButton: FloatingActionButton.extended(
onPressed: (){},
label: Text("Next",),
icon: Icon(Icons.arrow_forward,
),
),
floatingActionButtonLocation: FloatingActionButtonLocation.endFloat
There isn't any direct way to do that.
But as a workaround, you could just pass a Row widget (Which contains a Text and Icon widgets) to label parameter.
floatingActionButton: FloatingActionButton.extended(
onPressed: () {},
label: Row(
children: <Widget>[Text("Proceed"), Icon(Icons.arrow_forward)],
),
icon: Container(),
),
Hope it helps.
I don't think you can do that with FloatingActionButton, but instead you can configure a RaisedButton to look very similar.
Just use it same as you would do it with FloatingActionButton.
floatingActionButton: RaisedButton(
child: Container(
height: 50.0,
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
const SizedBox(width: 16.0),
Text('Next', style: TextStyle(color: Colors.white, fontSize: 25),),
const SizedBox(width: 8.0),
Icon(Icons.arrow_forward, size: 30.0, color: Colors.white,),
const SizedBox(width: 20.0),
]),
),
color: Colors.blue,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(30.0),
),
onPressed: () {
print('Do somenthing');
},
)
Hope this help.

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.
How do I add a new column to a Card in flutter?
Currently, I have 2 Columns and can't figure out how to add a third between these since they are on the left and right sides. When I have tried adding a "new Column", it only creates a new row of text under the first Column.
This is my code so far:
Widget _buildListItem(BuildContext context, Record record) {
return Card(
key: ValueKey(record.activityName),
elevation: 8.0,
margin: new EdgeInsets.symmetric(horizontal: 10.0, vertical: 6.0),
child: Container(
decoration: BoxDecoration(color: Color.fromRGBO(64, 75, 96, .9)),
child: ListTile(
contentPadding:
EdgeInsets.symmetric(horizontal: 20.0, vertical: 10.0),
title: Text(
record.activityName,
style: TextStyle(color: Colors.white, fontWeight: FontWeight.bold, fontSize: 23),
),
subtitle: Row(
children: <Widget>[
new Flexible(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
RichText(
text: TextSpan(
text: "Activations: "+record.activations+
"\n"+record.dateCompleted,
style: TextStyle(color: Colors.white),
),
maxLines: 2,
softWrap: true,
)
],
)
)
],
),
trailing: Container(
child: Hero(
tag: "avatar_" + record.activityName,
child: CircleAvatar(
radius: 32,
backgroundImage: NetworkImage(record.icon),
backgroundColor: Colors.white,
)
)
),
onTap: () {
Navigator.push(
context, MaterialPageRoute(builder: (context) => new DetailPage(record: record)));
}
),
)
);
}
I am wanting 3 columns so that I can add either an image in the middle of this card.
Current output
Expected output
Based on your screenshot, here is the solution. You can modify it according to your needs.
Widget _buildListItem(BuildContext context) {
return Card(
margin: EdgeInsets.all(12),
elevation: 4,
color: Color.fromRGBO(64, 75, 96, .9),
child: Padding(
padding: const EdgeInsets.symmetric(vertical: 8.0, horizontal: 16),
child: Row(
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text("Jumping", style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold)),
SizedBox(height: 4),
Text("Activations 9", style: TextStyle(color: Colors.white70)),
Text("03-08-19", style: TextStyle(color: Colors.white70)),
],
),
Spacer(),
CircleAvatar(backgroundColor: Colors.white),
],
),
),
);
}
Output:
Good morning. I made this screen and it works like a charm on high resolutions. Problem is, I want to support lower resolutions like Nexus 4 (768x1280).
So when I run this on an emulator (Nexus 4 size) and I touch the input fields, the keyboard either: blocks the inputs, or moves the two buttons at the bottom and overlaps them on something else.
So, to solve it I wrapped the entire layout on a ListView(), but now the bottom buttons, which are wrapped on a Row(), just won't stay at the bottom.
This is my code without the ListView and working on high res, but not on low:
return Form(
Stack(
Center(
Column(
...
),
),
Align(
alignment: Alignment.bottomCenter,
child: Row(
...
),
),
),
);
This is how it looks with resizeToAvoidBottomPadding: false
And this is how it looks with the value set to true
Thanks, everyone.
Did you try to use SingleChildScrollView ?
It is a widget for making the page able to resize the height and as well scrolling , for the listview thats not what is the listview for , you should add listview when you get an unknown amount of data,
We don't normally use it to just adjust the view.
ok so i edited the code as in here and i can scroll normally after the keyboard pop up and the view is good and i can click on the button normally try it.
Widget formWidget(){
return new Scaffold(
// appBar: AppBar(
// // Here we take the value from the MyHomePage object that was created by
// // the App.build method, and use it to set our appbar title.
// title: Text(widget.title),
// ),
body:Column(

In your Scaffold can you try this.
Scaffold(
resizeToAvoidBottomInset: false,
...
);
I position two elements in the center and bottom of the screen by this code.
body: Column(
children: [
Expanded(
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
SizedBox(

width: 80,
child:
Image(image: AssetImage("assets/images/logo.png"))),
SizedBox(height: 10),
Text(
"Tings App",
style: TextStyle(fontSize: 36),
),
SizedBox(height: 10),
TextFormField(
controller: _emailController,
decoration: InputDecoration(
border: OutlineInputBorder(),
isDense: true,
labelText: 'Email/phone'),
validator: (value) {
if (value.isEmpty) {
return 'Please enter a valid email';
}
return null;
},
),
],
),
),
),
Align(
alignment: Alignment.bottomCenter,
child: Container(
padding: EdgeInsets.all(20),
child: Column(
