我似乎无法正确配置react native app的实时数据库。

• 我已经在Firebase上创建了这个项目。
• 我添加了一个“Web应用程序”。
• 我检查了一下，似乎我的权限允许读/写。
• 我复制了配置文件
• 使用npm安装firebase

不幸的是，对数据库的写尝试似乎没有显示。我不太确定是因为我没有正确配置应用程序，还是我用于设置写的代码错误
my package.json：

在一个名为firebaseConfig.tsx的文件中，我有以下内容：

const firebaseConfig = {
    apiKey: "aaaaaaaaaa",
    authDomain: "bbbbbbbbbb",
    databaseURL: "cccccccccc",
    projectId: "dddddddddd",
    storageBucket: "eeeeeeeeeee",
    messagingSenderId: "ffffffff",
    appId: "gggggggggg",
    measurementId: "hhhhhhhhhhh"
};

const app3 = initializeApp(firebaseConfig)

export {app3};

型
在此之后，我使用以下代码尝试写入我创建的数据库：

import { getDatabase } from 'firebase/database';
import {set,ref} from 'firebase/database'
const db = getDatabase(app3)

function writeUserData(userId, name, email) {
  set(ref(db, 'users/' + userId), {
  username: name,
  email: email

});
}

型
然后我有一个按钮激活如下：

function TestFirebaseScreen({navigation}: any) {
  function writeUserData(userId: string, name: string, email: string) {
    
    set(ref(db, 'users/' + userId), {
      username: name,
      email: email,
    }).then(() => console.log("success"))

  }

    return (
      <SafeAreaView>            
        <Button  
          title = "test"
          onPress={() => writeUserData("abc", "a", "b")}
        />
      </SafeAreaView>
    );
}

export default TestFirebaseScreen

当我在firebase上查看我的数据库时，数据库仍然是空的。有人能提供一些见解吗？
