How is file multi upload done correctly in Symfony? Is there an example?

Question

symfony

Hello!
I'm looking for an example of a well-made functionality for multiple file uploads on Symfony.
I'm imagining a one-to-many relationship persistence solution using embedded form collection . Because in addition to the link to the file, I also want to save additional information: a description of the picture and the date it was uploaded/modified.
Everything that I found on the Internet was done either for one file, or strange and on hacks.
That is, you need a project to study in which, for example, a gallery of pictures is attached to a product with the possibility of adding / deleting them and then saving the updated product. Or something similar ideologically.
Does anyone have something similar in mind?
Thanks in advance!
