我将Firebase插件用于Web，并设法使用Firestore和身份验证。现在，我试图启用Firebase存储，但是当我实例化存储时，出现此错误
tried to call a non-function, such as null: 'dart.global.firebase.storage
用于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();
解决了！
在 index.html中 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');
