Required file input

Does Uppy support required: true option? I would like to display a warning message if a user submits for without uploading any file.

To my knowledge, there is not an explict required option, but there is a way to achieve the same effect using the restrictions option

Here is a brief code snippet

const uppy = Uppy({
 restrictions: {
    minNumberOfFiles: 1,
 // The rest of the uppy config

If you would like to look further into this, here is the link from the docs

This should work, but let me know how it goes for you.
