File input decorators

[DocAmaroo]

Hi! I searched for similar issue to avoid duplicate, but I cannot find one, so here I am to post my “issue” / potential feature.

I was looking for decorators, just like the @rxweb/reactive-form-validators provides, but it seems not have been implemented. It would be so elegant to use them this way, and keep all this logic in a single input class, just like the example below:

export class UserInputs {
  @required()
  @email()
  email: string;

  @prop()
  @maxFileSize(1024)
  @extensionAccepted('.zip') // => string or regular expression
  profilePicture: FileInput;
}

This way will could follow how rxweb implement it to create custom messages or even more.

Thanks for your time :)
