How to mutate/format data for dehydration? (When using a custom field class)

Hi there, I know how to do this using the premade filament fields. I created a custom field component. And it works great. But I need to mutate the data that comes from the database so it display properly on my custom text field. Laravel returns back a custom cast object when accessing it from the database (not a singular raw string). So I need to be able to mutate that data to grab a single key from the array. otherwise nothing displays on the UI. TLDR: how do i use the functionality of (formatStateUsing or dehydrateStateUsing) within a custom component class? https://filamentphp.com/docs/3.x/forms/fields/custom#custom-field-classes

    TextInput::make('A field')
        ->formatStateUsing(function (MoneyInput $component, $state) {
            ...
        })
        ->dehydrateStateUsing(function (MoneyInput $component, $state) {
            ...
        });

    TextInput::make('A field')
        ->formatStateUsing(function (MoneyInput $component, $state) {
            ...
        })
        ->dehydrateStateUsing(function (MoneyInput $component, $state) {
            ...
        });

I've tried mutating the data within the setup() function but that doesn't work... Thanks for your help!

Nevermind, figured out I need to use the hydrate method since that's what fills out the form.
