This Week in Flutter: March 22, 2026

This week’s Flutter news has a strong “build for the real world” theme: from Genkit Dart’s new full-stack AI story to practical guidance on security, localization, performance, and app resilience. It’s also a nice reminder of Flutter’s range, with standout examples spanning high-FPS custom rendering, embedded Linux, and a couple of handy packages that make production apps easier to ship and maintain.
