How to Properly Pass An Updater<DeepValue> Function To form.setFieldValue

[TYMG]

I'm trying to set the value of field using form.setFieldValue function as shown in the Listeners section of the Basic Concepts Page and in this discussion, Shouldn't form.setFieldValue trigger the field validation by default? But I'm seeing the following compilation error: Argument type (prev: any) => boolean is not assignable to parameter type Updater<DeepValue<{checked: false}, ".checked">>

My example:

 const form = useForm({
        defaultValues: {
            checked: false
            
        },
        onSubmit: async ({value}) => {
            // Do something with form data
            console.log(`${JSON.stringify(value)}`)
            alert("SUBMIT PRESS")
        },
    })


   const checkboxChangeHandler = (value:boolean) => {
         console.log(`Checkbox clicked: ${value}`)
        form.setFieldValue('.demoApplication', value) <--- This is the error 
    };

I understand that I need to pass a function for the Updater, but I'm not sure what the arguments for that should be or what should be returned.

I've tried the following:

   form.setFieldValue('.checked', (prev) => {
            return !prev.checked.value
        })

But still saw the error. Any advice would be appreciated.
