Support Android v2 embedding

Please consider migrating the the package to the v2 embedding.

I just noticed the same thing. Just for info it warns like this now, at least on Flutter dev channel.

The plugin `image_editor` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android 
V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.

If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: 
https://flutter.dev/go/android-plugin-migration.
