I’d like to be able to validate the dimensions of an uploaded image but the validators seem to run during the initial upload which takes place before the Preview Step where cropping can be done. We have a set Crop ratio we want to use and it’s a likely scenario that after the cropping is done an image will meet the dimension requirements but not before. The docs state:
It is better to use validators instead of checking file properties in widget.onChange and widget.onUploadComplete callbacks. Validators are activated before a dialog gets closed thus improving your UX.
So is it possible to validate the after crop dimensions?
