Fixing Cloud Firestore Not Saving Data in Flutter: A Complete Guide

Are you facing issues with Cloud Firestore not saving data while working on your Flutter project? You're not alone! Many Flutter developers encounter problems when integrating Firebase, especially when they are just starting. In this guide, we will help you troubleshoot the issue of Cloud Firestore failing to create collections or documents and provide a detailed solution to get things running smoothly.

Understanding the Problem

In this scenario, a Flutter developer is trying to register a new user and create a corresponding document in Firestore with default values. Despite successfully registering the user, no document or collection is created in Firestore. Let's examine the key components involved:

The Firestore Rules are set to Test Mode allowing access up to a specified date.

The registerWithEmailPassword function is called to create a user.

Upon successful registration, a document should be created using updateUserData in the DatabaseService class.

Possible Causes of the Issue

Improper Firestore Configuration: If the Firestore setup isn't correctly configured or if you are operating under restrictive rules, data may not get saved as expected.

Plugin Compatibility: One of the most common reasons for this error is related to your Flutter Firebase plugin being out of date or incorrectly set up.

Error in Code Implementation: Sometimes the implementation of Firebase methods can lead to runtime issues.
