Spring has officially arrived 🌸—and while we’re likely waiting until Google I/O for the next stable Flutter release, there’s already plenty happening in the ecosystem.
This month’s newsletter covers:
- Flutter’s updated 2025 roadmap
- What’s new in the latest beta release
- Upcoming formatter changes and new IDE assists in Dart 3.8
- Hand-picked articles about common Flutter mistakes, app security, and more
Let’s dive in! 🚀
🧭 Flutter 2025 Roadmap Update
The Flutter team has shared their official 2025 roadmap, outlining key focus areas for the year.
Highlights include:
- Interoperability on iOS & Android: Continue experimental work to support direct calls from Dart to Swift/Obj-C (iOS) and Kotlin/Java (Android). This includes calling APIs that can only be invoked on the main OS/platform thread.
- Web Platform: Hot reload support, better performance, improved accessibility, and the removal of legacy HTML/JS libraries.
- Core Framework: Investigate changes to reduce verbosity in Flutter widget code and streamline development.
- Dart Language Improvements: Enhancements to code generation, new language features, and a refactored analyzer for better performance and tooling.
Personally, I’m most excited about hot reload for Flutter web (finally!), as well as new Dart language features and build_runner improvements.

🆕 Wanna help Flutter? Try out the beta!
The last stable release—Flutter 3.29—introduced some big changes (like Impeller on Android) and left many developers frustrated with regressions and waiting for hotfixes.
The Flutter team is now encouraging developers to test the latest beta and report bugs early. If you want to help shape the next stable release, now’s a great time to get involved:
I think this will help iron out potential issues before the next stable release. It also means we can already try out some of the upcoming changes. 👇
⌨️ Dart 3.8: Formatter Improvements
The new formatting style introduced in Dart 3.7 was quite controversial, with many people against the decision to automatically remove trailing commas.
The good news? Dart 3.8 will introduce an opt-in formatter config to preserve trailing commas.
To try it out, upgrade to the latest beta and add the following to your analysis_options.yaml:
formatter:
trailing_commas: preserve
