For lazy loading of the image you can check cached_network_image package. It provides progressIndicatorBuilder for showing the progress of the image load.

For example (taken from the library documentation),

CachedNetworkImage(
    imageUrl: "http://via.placeholder.com/350x150",
    progressIndicatorBuilder: (context, url, downloadProgress) => 
            CircularProgressIndicator(value: downloadProgress.progress),
    errorWidget: (context, url, error) => Icon(Icons.error),
 ),

For video player can check video_player library. If you want use caching feature for video also can check cached_video_player, which is made extending the video_player package.
