How can firebase services be called more efficiently in flutter to avoid resource waste?

edit

Use StreamBuilder for real-time data updates: Instead of repeatedly calling a Firebase service, you can use StreamBuilder to listen for any changes in the data. This helps reduce the number of requests made to the Firebase database.

Implement Cache Mechanism: Cache can be highly useful when it comes to improving the performance of your app. You can use the cache to store frequently accessed data, so the app does not have to request it from Firebase every time.

Limit the amount of data: You can limit the amount of data being retrieved from Firebase by applying filters, sorting, or pagination techniques, so you only fetch the data you need or essential data for the app.

Use FireStore Transaction and Batched Write: Use Firestore transactions or batch writes while performing multiple operations to the same document to avoid conflicts.

Use Firebase Analytics: Firebase analytics provides valuable insights about user behavior, such as how long they spend on different pages, and which features they use the most. So, you can optimize the app and conduct A/B testing based on user behavior and needs.

Use Cloud Functions: Cloud functions provide server-side logic for your Firebase app. By utilizing cloud functions, you can reduce the number of requests made to the Firebase database, improving the overall efficiency of your app.
