How to make responsive svg -flutter - flutter

Question

What is the best way to get a responsive svg image, I thought about using MediaQuery, but probably not quite it will fit for every screen.
I used Stack and Positioned because I have more things to lay on one screen that will overlap.
I want to make responsive this:
class Shape extends StatelessWidget {
static Route route() {
return MaterialPageRoute<void>(builder: (_) => Shape());
}
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Colors.transparent,
leading: IconButton(
icon: const Icon(Icons.arrow_back_ios, color: Colors.black),
onPressed: () => Navigator.of(context).pop(),
),
),
body: _profilePage(context),
);
}
Widget _profilePage(BuildContext context) {
return SafeArea(
child: Align(
child: Center(
child: Stack(children: <Widget>[
Positioned(
width: MediaQuery.of(context).size.width * 1,
height: MediaQuery.of(context).size.height,
top: MediaQuery.of(context).size.width * 0.4,
child: _curved(context),
),
]),
),
),
);
// });
}
Widget _curved(BuildContext context) {
return SvgPicture.asset(
'assets/images/shape_curved.svg',
color:Colors.green,
allowDrawingOutsideViewBox: true,
);}

Flexible(

child: Container(

child: Container(
decoration: BoxDecoration(

borderRadius: BorderRadius.only(
