title: Flutter MissingPluginException(No implementation found for method getAll on channel ...) in release app
body: <p>I got the MissingPlugin error. I found quite some posts about the error. But my case is a bit different.
  First, my project runs fine in simulator, the error only raises when I run my release app on physical Android.
  Second, this error is not just related to one package. I first got error like
  MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)
  After I put the code I found only to handle the issue with shared_preferences. I then got error like
  MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/package_info)
  Obviously the error is not just linked to one package like shared_preferences.</p>
  <p>Any idea? how can I solve the problem？</p>
