I'm trying to learn how to use hooks and context in React, but need to work with TypeScript (new to that as well).

I am confused about what to set provider value on my below code. I have created a hook useFirebase it will return some functions like RegisterUser, SignIn, user(it's a state), logout.

First I created UseAuth.tsx hook, using this hook I want to import the above functions which I mentioned.

import { useContext } from 'react';
import { AuthContext } from '../context/AuthProvider';

const UseAuth = () => {
    const auth = useContext(AuthContext)
    return auth
};

export default UseAuth;

Everything is ok but I am getting an error on the provider value. The error is (JSX attribute) React.ProviderProps<null>.value: null Type '{ RegisterUser: RegisterUserFunction; SignIn: SignInUserFunction; user: userState; logout: () => void; }' is not assignable to type 'null'. The expected type comes from property 'value' which is declared here on type 'IntrinsicAttributes & ProviderProps<null>' I have created an interface IAuth but where I need to define it I am confused.

import React, { createContext } from 'react';
import { UseFirebase } from '../hooks/UseFirebase';


export const AuthContext = createContext(null)

export interface IAuth {
    RegisterUser: () => void;
    SignIn : () => void;
    user : any
    logout : () => void;

}

const AuthProvider = ({ children } :any) => {
    const allContext = UseFirebase()
    return (
        <AuthContext.Provider value={allContext}>
            {children}
        </AuthContext.Provider>
    );
};

export default AuthProvider;
