function in React Native is not defined

Hello all currently my problem is that I am trying to make a onRegisterPress function in the useAuth class. I keep getting a bug saying Render Error: onRegisterPress is not defined

My onLoginPress function works completely fine so I am trying to figure out what the issue is.

useAuth.js

import React, { createContext, useContext } from "react";
import { auth } from "../model/config"; //this is my firebase auth settings
import {
  signInWithEmailAndPassword,
  createUserWithEmailAndPassword,
} from "firebase/auth";

const AuthContext = createContext({});

export const AuthProvider = ({ children }) => {
  const onLoginPress = (email, password) => {
    //Takes in two arguments, email and password used in LoginScreen class
    signInWithEmailAndPassword(auth, email, password)
      .then((userCredential) => {
        // Signed in

        const user = userCredential.user;
        console.warn("signed in");
        console.warn(user);
        //Navigate after sign in
        // ...
      })
      .catch((error) => {
        //If any error we will catch
        const errorCode = error.code;

        if (errorCode === "auth/user-not-found") {
          console.warn("User not found");
        }

        if (errorCode === "auth/wrong-password") {
          console.warn("Wrong password");
        } else {
          console.warn(error);
        }
      });
    const onRegisterPress = (email, password) => {
      if (password !== confirmPassword) {
        alert("Passwords don't match.");
      }
      createUserWithEmailAndPassword(auth, email, password)
        .then((userCredential) => {
          const user = userCredential.user;
          alert("Welcome");
        })
        .catch((error) => {
          alert(error);
        });
    };
  };
  return (
    <AuthContext.Provider value={{ user: null, onLoginPress, onRegisterPress }}>
      {children}
    </AuthContext.Provider>
  );
};

export default function useAuth() {
  return useContext(AuthContext);
}

I am using this class to interact with my LoginScreen and my RegistrationScreen.

Am I exporting this class incorrectly?

RegistrationScreen.js

import { Image, Text, TextInput, TouchableOpacity, View } from "react-native";
import { KeyboardAwareScrollView } from "react-native-keyboard-aware-scroll-view";
import styles from "./styles";
import { auth } from "../../model/config";
import { getAuth, createUserWithEmailAndPassword } from "firebase/auth";
import useAuth from "../../hooks/useAuth";

export default function RegistrationScreen({ navigation }) {
  const [fullName, setFullName] = useState("");
  const [email, setEmail] = useState("");
  const [password, setPassword] = useState("");
  const [confirmPassword, setConfirmPassword] = useState("");

  const { registerUser } = useAuth();

  const onFooterLinkPress = () => {
    navigation.navigate("Login");
  };

  return (
    <View style={styles.container}>
      <KeyboardAwareScrollView
        style={{ flex: 1, width: "100%" }}
        keyboardShouldPersistTaps="always"
      >
        <Image
          style={styles.logo}
          source={require("../../../assets/icon.png")}
        />
        <TextInput
          style={styles.input}
          placeholder="Full Name"
          placeholderTextColor="#aaaaaa"
          onChangeText={(text) => setFullName(text)}
          value={fullName}
          underlineColorAndroid="transparent"
          autoCapitalize="none"
        />
        <TextInput
          style={styles.input}
          placeholder="E-mail"
          placeholderTextColor="#aaaaaa"
          onChangeText={(text) => setEmail(text)}
          value={email}
          underlineColorAndroid="transparent"
          autoCapitalize="none"
        />
        <TextInput
          style={styles.input}
          placeholderTextColor="#aaaaaa"
          secureTextEntry
          placeholder="Password"
          onChangeText={(text) => setPassword(text)}
          value={password}
          underlineColorAndroid="transparent"
          autoCapitalize="none"
        />
        <TextInput
          style={styles.input}
          placeholderTextColor="#aaaaaa"
          secureTextEntry
          placeholder="Confirm Password"
          onChangeText={(text) => setConfirmPassword(text)}
          value={confirmPassword}
          underlineColorAndroid="transparent"
          autoCapitalize="none"
        />
        <TouchableOpacity
          style={styles.button}
          onPress={() => registerUser(email, password)}
        >
          <Text style={styles.buttonTitle}>Create account</Text>
        </TouchableOpacity>
        <View style={styles.footerView}>
          <Text style={styles.footerText}>
            Already got an account?{" "}
            <Text onPress={onFooterLinkPress} style={styles.footerLink}>
              Log in
            </Text>
          </Text>
        </View>
      </KeyboardAwareScrollView>
    </View>
  );
}
