React reducers, state not updating immediately - reactjs

Question

i am working on createContext and reducers, with reducers i am updating state value, but it is not updating value at a time, i did console.log(user); in onSubmitSave(), but in console log i am not getting its updated state at a time, i can see it works when i clicked on signin again, here i have attached my whole code, can anyone please look into it, and help me to resolve this issue ?
auth.js
import { createContext } from 'react';
const AuthContext = createContext({
user: null,
hasLoginError: false,
login: () => null,
logout: () => null
});
export default AuthContext;
signin.js
// Login button Click
async function onSubmitSave(e) {
e.preventDefault();
const messages = {
'itemUsername.required': 'Username cannot be empty.',
'itemPassword.required': 'Password cannot be empty.',
};
const rules = {
itemUsername: 'required',
itemPassword: 'required|string',
};
validateAll(state, rules, messages)
.then(async () => {
let data = await login(itemUsername, itemPassword);
console.log(data);
console.log("sdsds");
console.log(user);
setUserData(user);
})
.catch(errors => {
const formattedErrors = {
};
errors.forEach(error => formattedErrors[error.field] = error.message);
setState({
...state,
errors: formattedErrors
});
})
}
// End Login
App.js
const reducer = (state, action) => {
switch (action.type) {
case "login": {
const { username, password } = action.payload;
return {
...state,
hasLoginError: false,
user: {
id: 1,
username: USERNAME,
firstName: "Dev",
lastName: "To"
}
};
}
case "logout":
return {
...state,
user: null
};
default:
throw new Error(`Invalid action type: ${action.type}`);
}
};
