创建新用户并在 Firebase 数据库中添加新文档并在存储中添加图像

Question

I'm developing an app with flutter and I want to add information about the user account in the firebase database when I create it and add its profile image in the storage. And I want to be sure that either all of the operations succeed, or none of them are applied like transaction? Can you please tell me how doing it?

Answer 1

There is no way to perform a transaction across multiple Firebase services, such as Authentication and the Realtime Database here.

You'll have to assume that the data can get corrupted and define a strategy how to deal with that both in the code that consumes the user data, and possibly in (server-side) code that performs a periodic cleanup.
