Android 关闭flutter 页面后再次打开 image_picker 报Unhandled Exception: MissingPluginException(No implementation found for method pickImage on channel plugins.flutter.io/image_picker)

项目中使用了image_picker,在flutter_boost 3+上，第一次打开图片选择器正常，关闭当前flutter 界面，再次进来,打开图片选择器，就会报Unhandled Exception: MissingPluginException(No implementation found for method pickImage on channel plugins.flutter.io/image_picker) ，原来在 1.17.1 版本上的解决方案是 通过 问题 #816 完成的，最新版本如何解决？

Start by reproducing the image_picker flow on Flutter Boost 3+: open the picker, close the Flutter page, and open it again. Compare the lifecycle behavior with the solution referenced in issue #816; done means reopening the picker succeeds without MissingPluginException.
