DartError: Unsupported operation: Platform._operatingSystem

[mulin-xml]

Web platform, version 8.2.10

[Rezki-Pratama]

I suspect the error might be caused by the dart:io package being called on the web platform, where it is not supported.

import 'dart:io';
......
......
......
if (backgroundColor == null && Platform.isIOS) {
  backgroundColor = Colors.black;
}
if (textColor == null && Platform.isIOS) {
  textColor = Colors.white;
}
....
....
