Creates a preview of a file.
If the file is an image, a image preview will be shown. If not, an icon representing the filetype will be shown. When useCard is true, the extension's name will also be shown if the file is not an image.
When useCard is true, the user will be able to interact with the preview through onTap and onDelete.
