I've got stuck on a problem with a custom annotation I created for a while now in my Micronaut REST app. What I need my annotation to do is: read the value of a boolean field in my record class and if it is true activate the validation.
So, if isCompany is set to true then I want to make it so that annotated fields are not null, if set to false these annotated fields can be null.
My current code works however, the "true" value is hardcoded and I can't find a way to pass the value while making a POST.
Is there a way I can do it?
Custom annotation package:
