Ref In Functional Component, You can leverage functional callback to create refs for the NumberView component.

Ref In Functional Component, When using forwardRef , the component function receives props first, then ref second. We recommend defining components as functions instead of classes. The ref prop works directly on the Box component without needing forwardRef . If you need a ref to a functional component, you should change the component  In React, a ref is a special attribute that is used to reference an instance of a class component or DOM element. useRef is a React Hook for values not needed for rendering.
