无法在Flatter web版本中将图像上载到firebase，今天可以吗？Android上的一切都很好 错误：

index.html：

<script src="https://www.gstatic.com/firebasejs/7.14.4/firebase-app.js"></script>
  <script src="https://www.gstatic.com/firebasejs/7.14.4/firebase-firestore.js"></script>
  <script src="https://www.gstatic.com/firebasejs/7.14.4/firebase-auth.js"></script>
