Unhandled Exception: 'package:flutter_downloader/src/downloader.dart': Failed assertion: line 390 pos 12: 'callbackHandle != null': callback must be a top-level or a static function

flutter应用内升级demo下载回调组件callback方法已改成静态方法，需要修改

本人已经不研究flutter一段时间了，抽空跑了下项目，发现下载组件使用方法跟之前不一样了。
希望有继续研究的小伙伴贴一下处理方法或者直接pr，给需要的人！

对应代码位置：
flutter-app-update-demo/app_update_demo/lib/download_progress_dialog.dart
第87行和120行

官方文档：https://pub.dev/packages/flutter_downloader#-readme-tab-
