Upon upgrading to Flutter 3.3.2 I"m not able to build my application due to 'open_file' plugin using a deprecated version of Android embedding. Is there a way to migrate said plugin to Android V2 embedding as recommended in the below warning message? Or I have to downgrate to Flutter 2.x.x?

The plugin `open_file` 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.
