Project mention: Android CLI: Build Android apps 3x faster using any agent | news.ycombinator.com | 2026-04-16
Yeah, I've been using Flutter since December last year and I'm really amazed how good the developer experience is. I kinda regret not picking it up sooner but from what I understand now's a great time too with the roadmap they've planned for this year (videos on YouTube explaining Flutter concepts and decoupling Material and Cupertino).
You can even make 2D games with Flutter with the help of Flame[0] but be wary that pixel art style games are a bit of a hassle due to some bugs in Flutter itself. Otherwise Flutter is a joy to use for its intended purpose, cross-platform apps.
