如何使用getParam从json文件获取数据？

如何使用getParam从文件（data.json）获取数据。我想逐行打印data.json中声明的数据。下面是我的content.js和data.json代码

content.js

import React from "react";
import { StyleSheet, View, Text, Button } from "react-native";
import data from "../data.json";

function content({ navigation }) {
  const userId = navigation.getParam("UserID", null);
  const firstName = navigation.getParam("First Name", null);
  return (
    <View style={styles.container}>
      <Text style={styles.details}>Details of Employee</Text>
      <Text> Reference Number: navigation.getParam("userId","")</Text>
      <Text> First Name: {firstName}</Text>
    </View>
  );
}

export default content;

{
  "employee": [
    {
      "userId": 1,
      "firstName": "Krish",
    },
  ]
}
