Resolving the Router Import Conflict in Flutter when using Fluro Package

Navigating through an application is a critical aspect of app development, and Flutter’s navigation system is a powerful one. However, when using third-party packages like the Fluro package for enhanced routing, developers may encounter some challenges, particularly with import conflicts. One common issue arises when both the Fluro package and Flutter's native library attempt to use the Router class, leading to confusion and compilation errors.

The Problem

If you recently upgraded your Flutter SDK to version 1.20.0 and notice an error akin to the following:

This indicates that both libraries have a Router class, and Dart doesn't know which one to use. This problem can prevent your application from compiling and functioning correctly, hindering your development workflow.

Solution: Adjusting Your Imports

Thankfully, resolving this import conflict is straightforward. You need to modify the way you import the Flutter package in your navigation class. Here’s how to do it:

Step-by-Step Fix

Locate the Import Statement: Look for the line in your navigation class where you import the Flutter material package.

Modify the Import: To avoid the conflict with the Router class from Fluro, adjust your import statement to hide the Router from Flutter. Change it to:

Verify Your Code: After making this change, ensure that your code compiles correctly and that you can successfully use Fluro’s routing functionality without ambiguity.

Why This Works

By using hide Router, you effectively tell Dart to ignore the Router class in the Flutter package. This allows you to utilize Fluro’s Router exclusively, preventing any naming conflicts.

In Conclusion

Import conflicts can be a frustrating aspect of using libraries in Dart and Flutter, especially when they cross over in functionality. Fortunately, with a simple tweak to your import statement, you can continue leveraging the robust navigation features provided by Fluro alongside Flutter’s powerful interface. By applying the fix we discussed, your project will remain on track and error-free.
