React 19 API Changes

⚠️ React 19+ only. Skip this if you're on React 18 or earlier.

In React 19, ref is now a regular prop (no forwardRef wrapper needed), and use() replaces useContext().

Incorrect (forwardRef in React 19):

const ComposerInput = forwardRef<TextInput, Props>((props, ref) => {
  return <TextInput ref={ref} {...props} />;
});

Correct (ref as a regular prop):

function ComposerInput({ ref, ...props }: Props & { ref?: React.Ref<TextInput> }) {
  return <TextInput ref={ref} {...props} />;
}

Incorrect (useContext in React 19):

const value = useContext(MyContext);

Correct (use instead of useContext):

const value = use(MyContext);

use() can also be called conditionally, unlike useContext().
