Null check operator used on a null value

I keep on getting the error. I believe it comes from the video compress package

In video.dart under models folder ,just add this

static Video fromSnap(DocumentSnapshot snap) {
var snapshot = snap.data() as Map<String, dynamic>;
return Video(
caption: snapshot['caption'] ?? '',
commentCount: snapshot['commentCount'] ?? 0 as int ,
id: snapshot['id'] ?? '',
likes: snapshot['likes'] ?? [] as List,
profilePhoto: snapshot['profilePhoto'] ?? '',
shareCount: snapshot['shareCount'] ?? 0 as int,
songName: snapshot['songName'] ?? '',
uid: snapshot['uid'] ?? '',
username: snapshot['username'] ?? '',
videoUrl: snapshot['videoUrl'] ?? '',
thumbnail: snapshot['thumbnail'] ?? '');
}
}

instead of this

static Video fromSnap(DocumentSnapshot snap) {
var snapshot = snap.data() as Map<String, dynamic>;

return Video(
username: snapshot['username'],
uid: snapshot['uid'],
id: snapshot['id'],
likes: snapshot['likes'],
commentCount: snapshot['commentCount'],
shareCount: snapshot['shareCount'],
songName: snapshot['songName'],
caption: snapshot['caption'],
videoUrl: snapshot['videoUrl'],
profilePhoto: snapshot['profilePhoto'],
thumbnail: snapshot['thumbnail'],
);
}
}
