Steps to Reproduce

In out of the box vanilla flutter project, add image picker plugin.
image_picker: ^0.6.7+4

Expected results:
The plugin works in debug variant for picking the images from Gallery.
But when Flutter App is signed with certificate and installed in release build variant, the App crashed on the App run from the start.

Actual results:
Plugin is missing the classes as seen in the exception. Perhaps proguard is removing the classes in the release build.
