Fixing the Flutter Text-to-Speech Issue: Why It May Not Work on iOS 16

If you're diving into the world of Flutter and trying to implement a text-to-speech feature using the flutter_tts package, you might run into an unexpected problem—it simply doesn't work! This can be frustrating, especially if you’ve followed popular guides and examples without success.

In this guide, we’ll explore the potential reasons behind your flutter_tts package not functioning as expected, particularly for those using iOS 16, and how to troubleshoot it effectively.

Understanding the Problem

Many developers have reported issues with the flutter_tts package when running on the iOS 16 simulator, despite having set up their environment correctly. Common symptoms include:

No audio output when attempting to use the text-to-speech function.

Console logs showing various warnings or errors, such as “unable to list voice folder.”

Before diving into the solution, let's take a closer look at a sample code that demonstrates how the flutter_tts package is typically used.

Sample Code Review

Here's a brief recap of a sample Flutter implementation using flutter_tts:

Despite correctly implementing the code, many users have found that it yields no output on iOS 16.

The Solution: Downgrading Simulator Version

After putting in considerable time and effort, the breakthrough revelation was that the issue was linked to the simulator version being used. Specifically, migrating from iOS 16.0 to a lower version, such as iOS 15.5, resolved the problem.

Steps to Resolve the Issue

Check Simulator Version: Confirm which version of the iOS simulator you are currently utilizing. You can do this through Xcode.

Reverse to Previous Version: If you are on iOS 16.0, switch your simulator to an earlier version like iOS 15.5.

Test Your App Again: Re-run your Flutter application and attempt to trigger the text-to-speech functionality. In this case, it should work as intended!

Why This Works

When running on iOS 16.0, developers experienced issues with the flutter_tts package due to an error the Xcode console displayed: "unable to list voice folder." This indicates a potential regression or compatibility issue in the newer iOS releases affecting the text-to-speech capabilities.

By reverting to iOS 15.5, you can access the functionality of your text-to-speech features without running into these specific bugs.

Conclusion

It's not uncommon to run into issues while developing applications, especially with rapidly evolving platforms like Flutter and iOS. However, understanding where the problems may stem from and having the patience to troubleshoot is key to maintaining progress in your development journey.

If you find yourself facing issues with the flutter_tts package, remember: sometimes, the simplest solution is to look back at older, stable versions of your development environment while waiting for libraries to be updated.

Happy coding, and may your Flutter applications speak fluently!
