How to Fix the Firebase_auth depends on firebase_core Error in Your Flutter App

When developing a Flutter application that integrates Firebase, you may encounter a frustrating error message indicating a version conflict between the firebase_auth and firebase_core packages. This issue can prevent you from successfully running or building your app, which ultimately slows down your development process. In this guide, we will explore the nature of this problem and provide a straightforward solution to resolve it.

Understanding the Problem

The error arises when your project depends on different versions of Firebase packages that are not compatible with each other. In the case we are discussing, the project is trying to use:

firebase_auth: ^0.18.4+ 1

firebase_core: ^0.7.0

The error message states that firebase_auth requires firebase_core version ^0.5.3, which leads to a conflict because your project is referencing a higher version ^0.7.0. This version inconsistency creates a situation where the dependency solver is unable to find a satisfactory version combination of the packages, resulting in a failure during the pub get process.

Step-by-Step Solution

To fix this version conflict and ensure smooth integration of the Firebase packages into your Flutter application, follow these steps:

1. Modify Your Dependencies

Directly address the conflicting versions in your pubspec.yaml file by specifying exact compatible versions for both the firebase_auth and firebase_core packages. Here’s how you should structure your dependencies:

2. Run Flutter Clean (Optional)

After updating your dependencies, it may be beneficial to run flutter clean in your terminal. This command clears the build cache and resolves any lingering issues related to old builds.

3. Pull the Packages Again

Once you've set the compatible versions, run the following command to fetch packages:

This action will pull the specified versions of the packages into your project, allowing for compatibility between firebase_auth and firebase_core.

4. Test Your App

After successfully fetching the packages, it’s crucial to test your application to ensure everything is functioning correctly. Run your app using the following command:

Check for any outstanding errors or issues to confirm that the dependencies are now resolved.

Conclusion

Version conflicts are a common hurdle when working with dependencies in Flutter projects. By clearly defining compatible versions of firebase_auth and firebase_core in your pubspec.yaml, you can effectively resolve the Firebase_auth depends on firebase_core error. Keeping your dependencies up to date and aligned is key to ensuring a smooth development experience in Flutter.

Now that you have a clear understanding of how to fix this issue, you can continue developing your application without interruption. Happy coding!
