The problem I have is that BackdropFilter is applying the blur but on the top border of the child there is a white shadow (screenshot with black background).
The only way to remove it is to set sigmaY=0 but the blur is not homogeneous.
How can I fix it?
This is the code so far:
return Container(
color: Theme.of(context).accentColor,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
SizedBox(height: 5,),
SizedBox(
height: headerHeight,
child: Container(
decoration: new BoxDecoration(
image: new DecorationImage(
image: Image.network("https://coolbackgrounds.io/images/backgrounds/black/pure-black-background-f82588d3.jpg").image,//homeData.imageFromString.image,
fit: BoxFit.cover,
),
),
child: ClipRect(
child: BackdropFilter(
filter: ImageFilter.blur(sigmaX: 5.0, sigmaY: 15.0),
child: Container(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(
child: Row(),
),
CircleAvatar(
radius: 50,
backgroundColor: Colors.blueGrey,
backgroundImage: homeData.imageFromString.image,
),
SizedBox(
height: 10,
),
Text(
homeData.name,
style: TextStyle(fontSize: 30.0, color: Colors.white),
),
Expanded(
child: Row(),
),
],
),
),
),
),
),

Im trying to create a custom listTile which can expand if it has multiple lines and maintain photo centered but my problem is AutosizeText isn't working and if I wrap AutosizeText with Expand an error apears.
I can use listTile class if there is a method to know if is tree line or not
Can you help me to solve this?
here is my code:
Card(
elevation: 8,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Row(
children: [
SizedBox(
width: 70.0,
height: 70.0,
child: ClipRRect(
borderRadius: BorderRadius.circular(8),
child: Image.asset(
'assets/images/photo.jpg',
width: 70,
height: 70,
fit: BoxFit.cover,
),
),
),
SizedBox(
width: 24,
),
Column(
children: [
AutoSizeText(
'{otherUser.name! otherUser.lastName!}',
maxLines: 1,
style: Theme.of(context).textTheme.bodyText1!),
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
margin: const EdgeInsets.symmetric(horizontal: 2),
child: Image(
image: AssetImage(
'assets/icons/icon2.png'),
height: 20,
),
),
AutoSizeText(
otherUser.country![0],
maxLines: 2,
style: Theme.of(context)
.textTheme
.subtitle2!
),
],
),
Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
margin: const EdgeInsets.symmetric(horizontal: 2),
child: const FaIcon(
FontAwesomeIcons.locationDot,
size: 20,
color: Colors.black45,
),
),
AutoSizeText(
otherUser.location!,
maxLines: 2,
overflow: TextOverflow.ellipsis,
style: Theme.of(context)
.textTheme
.subtitle2!
),
]),
])
],
),
],
),
Row(
children: [Icon(Icons.star_half_outlined), Text("4.5")],
)
],
),
),
This may be due to the default minimum and maximum size in AutoSizeText widget. Change the minSize and maxSize parameter to some range that you need.

I'm trying to code a web site with Flutter.
I have a screen like this:
The text in the middle is just a little bit below. I want to take it a little higher. How can I do that?
Codes:
body: ListView(
children: [
Container(
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage("indexBackground.gif"),
colorFilter: ColorFilter.mode(Colors.blue.withOpacity(0.4), BlendMode.dstATop),
fit: BoxFit.cover,
),
),
height: MediaQuery.of(context).size.height - 55,
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text("3D Modelleme Hizmeti", style: TextStyle(fontSize: 30, fontWeight: FontWeight.bold, color: Colors.black),),
),
),
],
),
),
],
),
Thanks in advance for your help.
One way would be to use the EdgeInsets.fromLTRB constructor. In this example I increased the bottom padding to 30.0 which will raise up the text, you should adjust it to what works best for you.
padding: const EdgeInsets.fromLTRB(8.0, 8.0, 8.0, 30.0),
Try this:
body: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage("indexBackground.gif"),
colorFilter: ColorFilter.mode(
Colors.blue.withOpacity(0.4), BlendMode.dstATop),
fit: BoxFit.cover,
),
),
height: MediaQuery.of(context).size.height - 55,
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text(
"3D Modelleme Hizmeti",
style: TextStyle(
fontSize: 30,
fontWeight: FontWeight.bold,
color: Colors.black),
),
),
),
],
),
),
],
),
),
i've a card like this.
Actual card
but i want a card like this
What i want
My code is:
return Card(
semanticContainer: true,
clipBehavior: Clip.antiAliasWithSaveLayer,
margin: EdgeInsets.fromLTRB(20.0, 5.0, 20.0, 5.0),
elevation: 5.0,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(15),
),
child: Container(
padding: EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 5.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text('Example text'),
Text("20-06-2021 - 13:00",
style:
TextStyle(fontSize: 15, fontStyle: FontStyle.italic)),
Text("Example text"),
Text("Example text"),
],
),
Column(
children: <Widget>[
Flag(
'FR',
height: 40,
width: 40,
replacement: Text('Error'),
),
],
),
],
),
),
);
Now, i have fixed height and width, i'm not able to obtain what i want because each attempt enlarge the card in height.(I want to keep the same height as the card above).The icons comes from the package flags (Flags package)
Instead of wrapping a Container in a Card. Try to Wrap a Row with Expanded in the Card. (I just changed the Container into padding)
Card(
semanticContainer: true,
clipBehavior: Clip.antiAliasWithSaveLayer,
margin: EdgeInsets.fromLTRB(20.0, 5.0, 20.0, 5.0),
elevation: 5.0,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(15),
),
child: Padding(
padding: EdgeInsets.fromLTRB(15.0, 5.0, 15.0, 5.0),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Expanded(
flex: 1,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text('Example text'),
Text("20-06-2021 - 13:00",
style: TextStyle(
fontSize: 15, fontStyle: FontStyle.italic)),
Text("Example text"),
Text("Example text"),
],
),
),
Expanded(
flex: 1,
child: Container(
height: 100,
color: Colors.red,
),
)
],
),
),
),
try this
to let it fit the width and the height:
Flag('AD', height: double.infinity, width: double.infinity, fit: BoxFit.fill)
or maybe this:
Flag('AD', height: null, width: null, fit: BoxFit.fill)
I recommend to make this flag Expandable widget inside the row
wrapped your Flag inside SizedBox if you know what fixed size it is like this.
SizedBox(
height: 65,
width: 140,
child: Flag(
'FR',
replacement: Text('Error'),
fit: BoxFit.cover,
),
)

Nowadays i have two Rows with a blue Container, but between this Containers i'm facing a white line (i don't know if the flutter put padding or margin between the rows).
I try this way:
return Scaffold(
appBar: AppBar(
backgroundColor: Colors.lightBlue[800],
elevation: 0.0,
iconTheme: IconThemeData(
color: Colors.white, //change your color here
),
),
body: Column(children: <Widget>[
Row(children: [
Container(
color: Colors.lightBlue[800],
height: 170,
width: MediaQuery.of(context).size.width,
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Column(
children: <Widget>[
new Container(
width: 120.0,
height: 120.0,
decoration: new BoxDecoration(
shape: BoxShape.circle,
image: new DecorationImage(
fit: BoxFit.fill,
image: new NetworkImage(
"https://i.imgur.com/BoN9kdC.png")))),
Padding(
padding: const EdgeInsets.fromLTRB(0, 5, 0, 0),
child: Text("RENATO",
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 25,
color: Colors.white)))
],
),
]),
),
]),
Row(children: <Widget>[
Container(
color: Colors.lightBlue[800],
height: 100,
width: MediaQuery.of(context).size.width
)
],)
]),
drawer: Drawer(
child: SafeArea(
child: Padding(
padding: const EdgeInsets.all(18.0),
child: ListView(
children: <Widget>[
ListTile(
title: Text('Item1'),
)
],
),
),
),
),
);
This is the result:
How i can fix this?
Try remove the border from Container, or set the color of the border to
