How can I create a live user count on my firebase and flutter app?

Question

I want to include a text box on my app that displays how many users are currently on the app (concurrent users). I'm using Firebase and flutter and I'm wondering if anyone has any suggestions. I know firebase reports the amount of live users for analytics, but is there a way to take that data and show it to the users?

我会为每个用户使用像这里这样的presence状态观察器的组合，并将在线状态保存在数据库和一个简单的云函数中，该函数侦听更改并增加或减少总计数器。
