Flutter Firebase Offline Issues with Await: How to Resolve Slow Performance

When developing apps using Flutter and Firebase, maintaining smooth user experiences is paramount. One common problem developers face is handling offline scenarios, especially when using await for document references. If your users try to reorder items in a list while offline, the experience can become frustratingly slow.

In this guide, we’ll explore the problem in detail and provide a thoughtful solution to manage offline Firebase functionality effectively.

Understanding the Problem

When users are online, awaiting document references usually runs quickly, allowing changes to be reflected immediately. However, in scenarios where a user is offline:

Awaiting document references might take upwards of 20 seconds.

Not awaiting these changes can lead to discrepancies when the user goes back online, especially after multiple changes.

This situation raises a critical question: How can we manage document interactions without causing delays, especially when users might be offline?

Proposed Solution

To manage this issue effectively, follow these steps:

1. Check Internet Connectivity

Before making any calls to Firebase using await, check if the user is actually online. Here's a simple way to do this in Flutter:

2. Handling No Internet Scenarios

If the check indicates that the user is offline, redirect them to a different screen, possibly displaying a message about the lack of internet connectivity. You can provide a "Try Again" button for them to retry connecting.

3. Adjusting Document References

By modifying the source option based on connectivity, you can significantly increase the efficiency of your app when working offline. Users should not have to wait for operations to complete when they're offline.

4. Update Reordering Logic

With the connectivity check in place, you can enhance the reorderExercises function to manage the reordering of items efficiently. Here's a streamlined version of your function:

Final Thoughts

Dealing with Flutter Firebase offline issues can be challenging, but by checking internet connectivity and adjusting how you handle document references, you can create a more fluid user experience. This approach allows your users to continue interacting with your app without the frustration of long waits due to offline situations.
