How to solve hidden field (like in html forms) requirement

[sezeryesiltas]

Hidden fields are very comfortable in html forms.
I'm not sure but it might be good idea something like that:
FormBuilderHiddenField( name: 'id', )

You could consider just using Flutter's Visibility widget

This would be cool, to be able to have keys in the form that might be computed and aren't necessarily from a widget in the widget tree
