How to synchronously deliver data to redux?

Question

React

const Parent = (props) => {
  <Child/> // тут дочерний со своим состоянием
  <button className="parent-submit" onClick={() => postData()}/>
}

const Child = () => {// как доставить state в Redux по клику на .parent-submit
  const [state, setState] = useState({})
}

const postData = () => async (dispatch, getState) => {
const {base} = getState();
const {data} = base;
  axios.post(data)
}

There is a parent component, how to click on the .parent-submit button, send the state of the Child component to redux. At the same time, in the postData method, have time to receive it and send the actual data. Due to asynchrony, I sometimes do not have time to get the actual data of their child component.
