When using a text field is there a way to prevent the composable from triggering the onValueChange callback? For example let's say I only want the text field to allow numerical input.

You can filter in the callback and reject changes before they're applied.

TextField has a pretty complicated state story for reasons - but the value passed on recomposition is considered the source of truth

🤔…🤦 clearly was overthinking it lol

Wouldn’t it make more sense to set the keyboardOptions? I’m unsure if this prevents certain characters when using a physical keyboard or when pasting text into it

I did look into that route by providing a KeyboardOption with the type set to number. However that still allows any character as it does not prevent character input from a physical keyboard or pasting text.
