retrieve the values of sibling fields to use in rendering an inputComponent

How can I retrieve the values of sibling fields to use in rendering an inputComponent? For example I want to render the text value but with the font specified in the fontSize sibling field.

One thing I tried to do was to do a client.fetch query but the problem here is that I could find any kind of id being passed in a a prop in my “TextInput” component, so it wouldn’t be possible to corroborate this data to the data queried from the api.

This is a view of the input component as of now. I cropped the picture below where I put in my projectid and api key for obvious reasons.

Hi Matthew, could you try wrapping your component in

withDocument()

? As follows:
This should give you access to a

document

prop that contains your document's content.
