Yes I made some changes to replace compute method Thats only work on flutter to Isolate.run() it's run on dart
here is the old
/// Generate the PDF document as a memory file
// Future save() async {
// final os = PdfStream();
// if (prev != null) {
// os.putBytes(prev!.bytes);
// }
// // to isolate it because it frease app
// await compute(await _write,os);

// // await _write(os);
// return os.output();
// }

and there is the new

Future _save() async {
final os = PdfStream();
if (prev != null) {
os.putBytes(prev!.bytes);
}
await _write(os);
return os.output();
}
// isolate save in another thread to solve freezing app
Future save() async {
return
await Isolate.run(()async=> await _save());

}

using IsolateSave() method is solve freezing when save pdf file but it's not work for web

using IsolatedSave() method is solve freezing when save pdf file but it's not work for web
