React - setState does not update the value

Question

I am trying to update the state with a localStorage value in DidMount, but it is not updating:

type Props = {
};

type State = {
    id_evaluation: string,
};

c

setState works asynchronously so pass console.log as callback to get updated state.

this.setState({ id_evaluation: '1'}, () => console.log('2- ', this.state.id_evaluation));

when used as your code, console.log('2 - ', this.state.id_evaluation) is printing previous state not the updated state.
