SfSignaturePad: extremely bad performance in iOS after upgrading Flutter version #808
Description
The SfSignaturePad widget started performing very badly on iOS devices, seemingly after upgrading from Flutter 3.7 to 3.10. It is almost unusable for me.
The problem can be reproduced by creating a sample app only with the SfSignaturePad widget (code below) and running on any iOS device or simulator.
import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_signaturepad/signaturepad.dart';
void main() {
runApp(const MainApp());
}
class MainApp extends StatelessWidget {
const MainApp({super.key});
@override
Widget build(BuildContext context) {
return const MaterialApp(
home: Scaffold(
body: SfSignaturePad(),
),
);
}
}
