No More Anxiety: How to Use iOS Extensions in Your Flutter App
I think I’m not the only one who panics a little when I have to add a new iOS extension to an app, especially when it’s not a simple home screen widget or a share sheet! There are so many powerful extension types in iOS that we often overlook, but they can enable creative and seamless integrations with the iOS platform.
Most of these extensions traditionally require Swift code and tricky Xcode configuration. But what if I told you that in recent versions, it has become possible to run Flutter code inside extensions? Sounds amazing, right?
In this talk, I will:
• Introduce a wide range of iOS extensions and what they can do
• Show how to implement them — and the common pitfalls to watch out for
• Explain when and how you can embed Flutter in extensions, with practical examples
Whether you’re building deep platform integrations, want to extend your app’s reach on iOS, or are just curious about what’s possible, this talk will inspire you to go further.
Saving data before the app getting killed! Easy state restoration with Flutter
Imagine this scenario as a user: You are writing a long text in an app, keep switching between various apps, and return to the app, but notice the OS killed it! Now, all your written text is gone. What a terrible UX! How can we, as developers, help the user avoid running into this worst-case scenario? Simply keep and restore the app’s state! We always discuss state management but forget about restoration. For my newest app, "Japanana," I needed to include this feature. So, I will explain the implementation with an actual example. In this talk, I want to:
- Show how to enable state restoration
- Explain the differences between iOS and Android
- Implement the restoration of our app state and discuss various strategies including navigation
- Learn about multiple possibly unheard types such as RestorableInt and RestorableString
- Adjust our tests with this new behaviour
Comparing ways of accessing native functionality
How I came across this topic:
As part of developing one of my apps, I was interested in using the AirPods' sensors for data collection. For this purpose, I wrote a little package: https://pub.dev/packages/flutter_airpods
Which does precisely that. I used an event channel to get the information in real time and process it in my app. It was during the last Flutterforward that I heard for the first time about ffigen, which would have saved me a lot of development time. With ffigen, I can extract the class that provides all the functionality I need, create bindings, and call it directly from within Flutter. This talk will demonstrate the process and compare it to writing a bridge manually.
Takeaways:
- Auto-generate bindings to various languages like ObjC, Rust, and C++
- How ffigen can save a lot of time while developing
- Less maintenance since you can reduce the need for dependency
