馃憢 Hi everyone, I鈥檓 enabling GitHub Sponsors for Metro
If Metro has improved your developer experience or saved your team's build times, I鈥檇 appreciate the support!
Full pitch and ROI napkin math here: https://www.zacsweers.dev/sponsoring-metro/
Metro is the proudest work of my career. Ever since starting it on vacation in November 2024, building it has been an incredible journey and the community reception has been nothing short of wonderful. It sits at the intersection of several fields I've come to specialize in, ranging from metaprogramming

After three wonderful years at Amazon I'm happy to share that I started this week at ... Square / Block again on my old team 馃獌 I'm excited to think about developer productivity more deeply again.
I'm quite proud of what I accomplished with my team at Amazon and will miss them. I'll keep working on App Platform as much as I can thanks to open source! https://amzn.github.io/app-platform/
Our KMP framework App Platform now supports Metro out of the box: https://github.com/amzn/app-platform/releases/tag/0.0.6
@ZacSweers is pushing the boundaries with Metro and there are still some Kotlin compiler bugs that need to be resolved, but on the JVM / Android it works.
Metro is conceptional very similar to Dagger + Anvil and kotlin-inject-anvil, which made this migration easy. I expect most new development to happen for Metro, so I wouldn't use kotlin-inject-anvil for new projects anymore.
I've been using ktfmt over KtLint for a few months for some projects. It's a blessing and so much easier to deal with. I forgot how much I missed 2 space indent in Kotlin.
We published a new version of App Platform with back button support. We also added recipes for saving presenter state, app bar integration and backstack navigation.
Working with Compose in the business logic (Molecule) and UI (Compose Multiplatform) is so much fun.

馃ゲ Anvil was quite successful inside and outside of Square, but now it's time for the next big improvement. Metro is 95% of what I pitched as Dagger 3 within Square. I'm excited.
