I am quite a beginner at Flutter so I have a question why can't I fit sematicLabel in here?
Container doesn't have a property called semanticLabel. You can use instead Semantics.
Semantics(
label: 'Venus',
child: Container(
child: Image.asset('assets/images/venus.png'),
height: 200,
width: 200,
),
)

I am wondering if it is possible to repeat an actual icon widget like the image I have attached.
Currently getting this result using ImageRepeat but would like to be able to use and actual icon so it can be modular and the icon can change.
( the repeating image can currently change but I don't want to have to create 100 images of icons. )
Current Solution:
SizedBox.expand(
child: Image.asset(
_backGroundImage,
repeat: ImageRepeat.repeat,
)),
try Wrap:
Container(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height,
color: Colors.orange,
child: Wrap(
children: List<Widget>.generate(2000, (int index) {
return Icon(Icons.add);
}),
),
),
I am trying to get a text label with graphics over the image. Labels like new arrival, best seller, limited, on sale just like on the pic attached.
enter image description here
Here's what i think the skeletal layout would be :
return Stack(
children: [
Card(
color: Colors.black54,
child: Image.asset('assets/xyz.png'),
),
Align(
//for bottomRight
alignment: Alignment.bottomRight,
child: Image.asset(
'assets/fireimg.png',
), //can be an SVG converted to png
),
Align(
//for topLeft
alignment: Alignment.topLeft,
child: Image.asset(
'assets/label.png',
), //can be an SVG converted to png
),
],
);
Feel free to give the Padding of your choice.
it has so much code to write , so i will give some examples to achieve that output
in this image ,i mentioned 0 and one .
for all 1
solution 1
you can use image like this way
Stack(
children: [
Container(
width: 200,
height: 200,
color: Colors.amber,// added only for view this example
child:Image() // add Product image here
),
Positioned(
top: 20, //change according to your use case position
left: 0,// change according to your use case position
child: Container(
color: Colors.black, // added only for view this example
decoration: BoxDecoration(image: ),// add label image here
width: 100,
height: 50,
child: Row(
children: [Text('hi')],
),
))
],
)
solution 2
you can use custom paint for label layout
not that
in both solution you have to use stack and position widgets , you can control position according to your use case
for all 0
you can use RotationTransition widgets to achieve this
not that
you have to use stack and position widgets , you can control position according to your use case
for the vertical Text
use this example
String exText = "meta";
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('hi'),
),
body: Container(
width: 200,
height: 200,
color: Colors.amber,
child: Column(
children: exText.characters
.map((e) => Container(
child: Text('$e'),
))
.toList()),
),
out put will be
I want to decorate a container with a single stripe down the middle with white on each side like in the picture, I'm guessing I need to use Linear Gradient but I am struggling to get it right.Any Ideas?
Single Stripe Pic
Easy, You need to create a container and make a child of it as Stack and further create a container with aligned it to center. Give it some width and decorate it with linear gradient that's all
Here's some code I've written to help you. Feel free to customize on top of it and use within your app. Cheers!
Container(
width: 200,
height: 150,
color: Colors.white,
child: Stack(
children: [
Align(
alignment: Alignment.center,
child: Container(
width: 50,
color: Colors.red,
),
)
],
),
);
I have a widget that exceeds the size of the display and I would like to show different parts depending on user input.
When using this code:
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.red,
...
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Transform.translate(
offset: const Offset(-50, 0), // offset hardcoded to -50
child: Container(
width: 2000,
height: 100,
color: Colors.yellow,
),
...
The widget respects the constraints, so the container is fitted to the display. After the transform, you see the background instead of a continuation of the widget.
I could wrap the widget in an UnconstrainedBox:
UnconstrainedBox(
alignment: Alignment.topLeft,
child: Transform.translate(...)
)
This fixes the problem, but results in an error:
A RenderConstraintsTransformBox overflowed by 1500 pixels on the
right.
I want it to overflow, I don't think this is an error! Any ideas on how I can fix this?
Note: I could use a SingleChildScrollView with NeverScrollableScrollPhysics() and use the controller to set position, but to me, this feels like overkill. Hope there is a simpler method. Thanks for the read :)
UnconstrainedBox is not the widget to use for getting rid of inner child overflow warnings. It's used to loosen the constraints.
You can use an OverflowBox in this case. Usage example:
SizedBox(
width: 100,
height: 100,
child: OverflowBox(
minWidth: 150,
minHeight: 150,
maxWidth: 150,
maxHeight: 150,
child: FlutterLogo(),
),
)
How to achieve following shape in flutter without using plugins? I want to implement the customized container using clippath. I'm trying to use lineTo() method. I did not get exactly this one.
try this package, clippy_flutter, using Point:
Point(
triangleHeight: 30.0,
edge: Edge.LEFT,
child: Container(
color: Colors.pink,
width: 100.0,
height: 100.0,
child: Center(child: Text('Point')),
),
),
and then stack them and overlap a little at the egde.
