Hope you all are doing well. I am making a flutter application. In this interface I am having a issue. I am making a container and circle avatar which are in stack. In stack, in first widget container there is also another container. When I set image as a child to inner container it also applied to outer container. Why is this happening and what is the solution of this problem.
Stack(
children: [
// Container(child:
Container(
decoration: BoxDecoration(
border: Border.all(
color: Colors.indigo,
)),
width: 340,
height: 200,
child: Container(
child: Image.asset(
'assets/pic1.jpg',
fit: BoxFit.cover,
),
width: 340,
height: 150,
decoration: BoxDecoration(
border: Border.all(
color: Colors.black,
)),
),
),
Positioned(
bottom: 10,
right: 10,
child: CircleAvatar(
backgroundColor: Colors.grey,
radius: 40,
))
],
)
I think You just need to Alignment Property to your Parent widget otherwise child widget will not care about height and width
Stack(
children: [
// Container(child:
Container(
alignment: Alignment.center,
decoration: BoxDecoration(
border: Border.all(
color: Colors.indigo,
)),
width: 340,
height: 200,
child: Container(
child: Image.asset(
'assets/pic1.jpg',
fit: BoxFit.cover,
),
width: 340,
height: 150,
decoration: BoxDecoration(
border: Border.all(
color: Colors.black,
)),
),
),
Positioned(
bottom: 10,
right: 10,
child: CircleAvatar(
backgroundColor: Colors.grey,
radius: 40,
))
],
)

I am trying to make the display feature for my app, but I am having a hard time making these outer circles, any input is appreciated
There is a way to draw using coordinates.
You can set the ratio using MediaQuery.of(context).size.
return Scaffold(
body: SafeArea(
child: Stack(
children: <Widget>[
Positioned(
top: 200,
left: 80,
child: Container(
width: 200,
height: 200,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(128.0),
border: Border.all(color: Colors.blue),
),
),
),
Positioned(
top: 225,
left: 105,
child: Container(
width: 150,
height: 150,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(128.0),
border: Border.all(color: Colors.blue),
),
),
),
],
),
),
);
Use this:
Container(
color: Colors.white,
child: Center(
child: Container(
width: 200,
height: 200,
decoration: BoxDecoration(
gradient: const LinearGradient(
colors: [Colors.white,Colors.white, Colors.red, Colors.red, Colors.white,Colors.white],
transform: GradientRotation(pi / 2),
),
borderRadius: BorderRadius.circular(128.0),
),
child: Center(
child: Container(
width: 198,
height: 198,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(120.0),
),
),
),
),
),
),
It leads to this output:
use stack widget and put 2 circle containers with different size as children in stack widget
I'm new to flutter and not that experienced when it comes to programming in general. So I'm trying to do something like this
But I just can't seem to do it, I tried align properties, padding to make it move left and right, I also tried stacks but I don't have any idea how to do it.
This is my code for the image
Widget buildImage() {
return Padding(
padding: EdgeInsets.only(right: 10, left: 10, top: 20),
child: Align(
alignment: Alignment.bottomLeft,
child: Container(
height: 100,
width: 130,
decoration: BoxDecoration(
image: new DecorationImage(
image: new AssetImage(
"assets/images/profile-image.jpeg",
),
fit: BoxFit.cover,
),
shape: BoxShape.circle,
border: Border.all(
color: Colors.white,
width: 5.0,
),
),
),
));
}
This is my current progress
I would appreciate any help.
Here is the working code
Stack(
alignment: Alignment.bottomRight,
children: <Widget>[
Container(
height: 200,
width: 200,
child: InkWell(
onTap: () => {},
child: ClipRRect(
borderRadius: BorderRadius.circular(100),
child: Container(
height: 200,
width: 200,
color: Colors.grey[200],
child: Icon(Icons.person),
),
),
),
),
Container(
height: 60,
width: 60,
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Colors.white,
),
padding: EdgeInsets.all(5),
child: Container(
decoration: BoxDecoration(shape: BoxShape.circle, color: Colors.grey[200]),
child: IconButton(
icon: Icon(Icons.edit),
onPressed: () {},
),
),
),
],
);
This can be achieved with the Stack widget check the docs it has a video explaining it really well.
It lets you positions its children relative to the edges of its box.
You can use Stack to place widget over widget. Here is the working example
Stack(
alignment: Alignment.bottomRight,
children: <Widget>[
Container(
decoration: BoxDecoration(
image: new DecorationImage(
image: new AssetImage(
"assets/images/profile-image.jpeg",
),
fit: BoxFit.cover,
),
shape: BoxShape.circle,
border: Border.all(
color: Colors.white,
width: 5.0,
)),
height: 100,
width: 130,
),
Container(
height: 50,
width: 50,
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Colors.white,
),
padding: EdgeInsets.all(5),
child: Container(
decoration:
BoxDecoration(shape: BoxShape.circle, color: Colors.blue),
child: Center(
child: IconButton(
icon: Icon(Icons.edit),
onPressed: () {},
),
),
),
),
],
)
I am using a Stack to recreate this effect :
But for some reason, using the Ink widget to be able to get the gradient effect, this is what I have :
This is my code :
Stack(
children: [
SizedBox(
height: 100.0,
width: 100.0,
child: ClipRRect(
borderRadius: BorderRadius.circular(20.0),
child: CachedNetworkImage(
imageUrl:
'https://images.unsplash.com/photo-1570296767266-60ccc88974a5',
fit: BoxFit.cover,
placeholder: (context, url) => MC_Shimmer(),
),
),
),
Positioned(
right: -5.0,
bottom: -5.0,
child: SizedBox(
height: 30.0,
width: 30.0,
child: Ink(
decoration: BoxDecoration(
gradient: gradient,
borderRadius:
BorderRadius.all(Radius.circular(5.0)),
),
child: Icon(
OMIcons.cameraAlt,
color: Colors.white,
size: 15.0,
),
),
),
)
],
),
you can use Container instead of Ink and able to use gradient effect.
Positioned(
right: -5.0,
bottom: -5.0,
child: SizedBox(
height: 30.0,
width: 30.0,
child: Container(
decoration: BoxDecoration(
gradient: gradient,
borderRadius:
BorderRadius.all(Radius.circular(5.0)),
),
child: Icon(
OMIcons.cameraAlt,
color: Colors.white,
size: 15.0,
),
),
),
)
I tried this in dart pad it worked alright.
Positioned(
right: -5.0,
bottom: -5.0,
child: SizedBox(
height: 30.0,
width: 30.0,
child: Material(
child: Ink(
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.pink, Colors.yellow]),
borderRadius: BorderRadius.all(Radius.circular(5.0)),
),
child: Icon(
Icons.camera,
color: Colors.white,
size: 15.0,
),
),
),
),
)
Container(
// decoration: BoxDecoration(
// border: Border.all(color: Colors.black45),
// borderRadius: BorderRadius.circular(8.0),
// ),
child: Row(
children: <Widget>[
Container(
child: Text("hi"),
margin : EdgeInsets.fromLTRB(20, 8, 8, 16),
width: MediaQuery.of(context).size.width *0.42,
height: 90,
color: Colors.black12,
),
Container(
child: Text("Hi"),
margin: EdgeInsets.fromLTRB(16, 8, 8, 16),
width: MediaQuery.of(context).size.width * 0.42 ,
height: 90,
color: Colors.black12,
)
],
),
),
I can add border using Box decoration on the outer container, but it's throwing me an error when I am trying to do the same on the inner containers. What is the problem and how to solve it?
In order to add border on container inside row widget , we have to use decoration for the inner containers.
Once you will post the error, we can answer you better but i think the below code will be helpful for you.
If you are using decoration then you must not add colour attribute in container directly, it should be in decoration only.
Container(
child: Row(
children: <Widget>[
Container(
child: Text("hi"),
margin: EdgeInsets.fromLTRB(20, 8, 8, 16),
width: MediaQuery.of(context).size.width * 0.42,
height: 90,
decoration: BoxDecoration(
borderRadius: BorderRadius.all(Radius.circular(4)),
shape: BoxShape.rectangle,
border: Border.all(
color: Colors.blue,
width: 4,
)),
),
Container(
child: Text("Hi"),
margin: EdgeInsets.fromLTRB(16, 8, 8, 16),
width: MediaQuery.of(context).size.width * 0.42,
height: 90,
decoration: BoxDecoration(
borderRadius: BorderRadius.all(Radius.circular(4)),
shape: BoxShape.rectangle,
border: Border.all(
color: Colors.blue,
width: 4,
)),
)
],
),
),
In container widgets you cannot use the color and decoration at the same time. Remove the color property from the Container and move it into the BoxDecoration widget
This should work:
Container(
child: Row(
children: <Widget>[
Container(
decoration: BoxDecoration(
border: Border.all(color: Colors.black45),
borderRadius: BorderRadius.circular(8.0),
color: Colors.black12, //add it here
),
child: Text("hi"),
margin : EdgeInsets.fromLTRB(20, 8, 8, 16),
width: MediaQuery.of(context).size.width *0.42,
height: 90,
//color: Colors.black12, //must be removed
),
Container(
decoration: BoxDecoration(
border: Border.all(color: Colors.black45),
borderRadius: BorderRadius.circular(8.0),
color: Colors.black12, //add it here
),
child: Text("Hi"),
margin: EdgeInsets.fromLTRB(16, 8, 8, 16),
width: MediaQuery.of(context).size.width * 0.42 ,
height: 90,
//color: Colors.black12, // must be removed
)
],
),
),
Consider the humble Divider widget to keep things simple. If you add it to the bottom of a Column in your row it will add a line that will act as a border.
const Divider(height: 1.0,),
Stack(
children: <Widget>[
getChartView(widget.globalData.chartSelectValue),
Container(
decoration: BoxDecoration(
border: Border.all(
color: HexColor("#0C1C3B"), // <--- border color
width: 10.0,
),
),
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height - 280,
)
],
),
I want a click in getChartView() but the container is between click and chartview can any one help me?
yeah i got my answer. by me. this not a good solution but it's full fill my need for now :)
Stack(
children: <Widget>[
getChartView(widget.globalData.chartSelectValue),
Container(
decoration: BoxDecoration(
border: Border.all(

),
),
width: 10,
height: MediaQuery.of(context).size.height - 260,
),
Align(

child: Container(
decoration: BoxDecoration(

width: 10.0,
),
),
width: 10,

),
),
Align(

Stack(

GestureDetector(
child: Container(
decoration: BoxDecoration(

width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height - 280,
),
onTap: ()
{
getChartView(widget.globalData.chartSelectValue);
},
)
],
),
Well you may need to check your hierarchy, the way your view are rendered on top of each other cause your are using a stack. Another view might be getting the impulse instead of your getChartView(....)
Or you can use InkWell, which will handle the tap events and also animate the action.
InkWell(
onTap: () {
getChartView(widget.globalData.chartSelectValue);
},
child: Container(
decoration: BoxDecoration(
border: Border.all(
color: HexColor("#0C1C3B"),
width: 10.0,
),
),
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.height - 280,
),
),
