retrieveLostData method
Retrieves any previously picked file, that was lost due to the MainActivity being destroyed. In case multiple files were lost, only the last file will be recovered. (Android only).
Image or video can be lost if the MainActivity is destroyed. And there is no guarantee that the MainActivity is always alive. Call this method to retrieve the lost data and process the data according to your APP's business logic.
Returns a LostData object if successfully retrieved the lost data. The LostData object can represent either a
successful image/video selection, or a failure.
Calling this on a non-Android platform will throw UnimplementedError exception.
