问题 Currently in our realtime database, we have a planDetails node for each uid that has fields like startDate , endDate , planType . I want to track the number of users whose premium plan is active. I am trying to do this by making a firebase function that runs daily and updates a boolean custom user property, say isPremiumActive , to either true or false. I cannot just track the users who have purchased the premium plan because there are many who take the plan once and then don't renew it.

问题 I have a flutter app using Firebase's cloud firestore. I've done the web build and running it on Chrome through Android Studio works well.

问题 I have a collection in Firestore that contains a string for the next 365 days. It's effectively a codeword that our app needs to display on that particular day. We've noticed that if a user changes the date and comes back to the app, Firestore correctly returns the codeword for that day because our query uses today's date to query for the codeword. Previously, we had a bespoke API on a server that would fetch based on the server's time to ensure this couldn't happen. What would be the best
