So basically the effect which I'm trying to create is given below which is basically this ellipsis in the top left corner which is getting blended in the background. :
This is my implementation but I'm unable to achieve the desired result.
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: const Color(0xFF9465FB),
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text(widget.title),
),
body: Stack(
children: [
Positioned(
left: -105,
top: -56,
child: SizedBox(
width: 250,
height: 250,
child: Stack(
children: [
Positioned.fill(
child: BackdropFilter(
filter: ImageFilter.blur(
sigmaX: 8.0,
sigmaY: 8.0,
),
child: Container(
decoration: const BoxDecoration(
shape: BoxShape.circle,
color: Colors.white,
backgroundBlendMode: BlendMode.overlay,
boxShadow: [
BoxShadow(
blurStyle: BlurStyle.outer,
color: Colors.white,
blurRadius: 134,
)
]
),
),
),
),
],
),
),
),
const Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
],
),
),
],
),
);
}
}
I have tried giving spreadRadius also but it does not works.
