PreviewScreen throws error "Null check operator used on a null value" when opening video

[sreenath-n]

PreviewScreen widget doesn't support video. So it throws the error "Null check operator used on a null value" when trying to open video.

@sreenath-n yes same issue , and when we move "Go to all capture" button , we are able to see only images which are we capture previously not videos. Means that we neither be able to record video nor be able to save it. Can you find any solution regarding this issue then please comment !!

@sbis04 Please note this issue.
