Should we use PropTypes for Redux state?

Question

I have a very simple question for which I have not found any satisfying answer on web so far. Currently I am adding PropTypes in a react application. So, it has redux implemented and I was wondering if I should type check the state coming from redux.

I have a parent component lets say Component1, which renders three different components - something like this -

const Component1 = (props) => {
 return (
  <>
    <Component2 someProps={...} />
    <Component3 someProps={...} />
    <Component4 someProps={...} />
  </>
 )
}

export const mapStateToProps = (state) => {
  return { details: state.details }; //should I use proptypes to check type of details? //
};

export default connect(mapStateToProps)(Component1);

Does it make sense to type check the state coming from redux here? Thanks in advance.

Yes, it makes sense. Because it's props. And no matter where they are from

const Component1 = (props) => {
 return (
  <>
    <Component2 someProps={...} />
    <Component3 someProps={...} />
    <Component4 someProps={...} />
  </>
 )
}

Component1.propTypes = {
  details: PropTypes.shape({
    name: string,
    age: number
  })
}

export const mapStateToProps = (state) => {
  return { details: state.details }; //should I use proptypes to check type of details? //
};

export default connect(mapStateToProps)(Component1);
