ReactJS: Passing variable to another component

In one component I have:
const [dirty, setDirty] = React.useState(false);




In another component I have:
const AddItemForm = ({ setAddItem, addItem, dirty }) => {



I am trying to update dirty (when the form is changed) via:




So I can use this changed state in my other component - but how do you change the state as when I use setDirty it isn't available.
