Flutter web: 试图调用一个非函数，比如 null: 'dart.global.firebase.storage

Question

我正在使用适用于 Web 的 Firebase 插件并设法使用 firestore 和身份验证。现在，我正在尝试启用 firebase 存储，但是当我实例化 Storage 时出现此错误

tried to call a non-function, such as null: 'dart.global.firebase.storage

对于 firestore 和身份验证，我使用：

import 'package:firebase/firebase.dart' as fb;
import 'package:firebase/firestore.dart';

 fb.Auth _firebaseAuth = fb.auth();
  Firestore _firestore =fb.firestore();

用于存储：

fb.Storage storage = fb.storage();

已解决！

在index.html添加最新版本的firebase存储：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>

    <script src="https://www.gstatic.com/firebasejs/6.3.1/firebase-app.js"></script>
    <script src="https://www.gstatic.com/firebasejs/6.3.1/firebase-firestore.js"></script>
    <script src="https://www.gstatic.com/firebasejs/6.3.1/firebase-auth.js"></script>
    <script src="https://www.gstatic.com/firebasejs/6.3.1/firebase-storage.js"></script>
    <script defer src="main.dart.js" type="application/javascript"></script>
</head>
<body>
</body>
</html>

在yourClass.dart中：

import 'package:firebase/firebase.dart' as fb;

  fb.StorageReference _ref = fb.storage().ref('images');
