Inherited a massive Flutter codebase and no idea what's still in use?

We recently shipped ciach 🔪 – @LeanCodePl's new open-source CLI that finds never-referenced declarations by querying the Dart analysis server itself. So it reuses the analyzer's real cross-file reference search, not some homegrown guess.

💡 Perfect for:
- Cleaning up enterprise & legacy codebases
- Removing dead code with confidence
- Keeping codebases healthy by running it in CI

@ksztandur @LeanCodePl Sounds amazing! With such a clear migration path, using these forms will be a breeze

[Piotr Rogulski @PRogulskiDev]

Finally a good package for making forms in Flutter 💙

I'm proud to announce that we (@LeanCodePl) just shipped advanced_forms🚀 It's a new open-source form state package designed to save you time and make writing even the nastiest forms easy-peasy + it's built on plain Flutter, so no code gen or architecture is forced on you.

📝 Typed field controllers (text, checkbox, dropdown, multi-select, and custom ones).
⚖️ Composable validators that are mostly one-liners.
🔗 OOTB cross-field logic. Easily update field A the moment field B changes.
⏱️ Async validation with a debounce and timeout.
🌿 Easy subforms management. Nest sections, validate or reset the whole tree in one call. Let one field attach or drop a whole subform.
✅ 3 validation modes OOTB: on submit, on keystroke (+ debounce), and on unfocus.
📄 Really useful docs with graphics and real-life examples.
🤖An AI Agent Skill that writes the forms for you 👀

👆 We also recently created our in-house solution for this — seems like there's a big audience for tools like this in the Dart community 💙

Who do we have here? 👀 Excited to be talking about Flutter all over the world! See y'all in Cancún 🇲🇽

@Komoluszek And finally, thanks to the @ServerpodDev team for creating a wonderful config package: https://t.co/P6hIKXf1Nk 💙

[Piotr Rogulski @PRogulskiDev]

We've been busy improving ciach – our CLI for detecting and removing unused code from your Dart & Flutter projects. ✨

What's new?
- 📢 verbose mode, to see exactly what's going on
- ⚙️ support for config files, so that everyone on your team has the same experience
- 💡 better understanding of Flutter code patterns, to detect usages more accurately

ciach uses the Dart LSP extensively – and it proved to be an amazing tool for finding bugs in Dart itself 🐛

We already found (and fixed, thanks to @Komoluszek) these issues:
- https://t.co/HbZMHLpO77
- https://t.co/BMYv8jGSqB

Look out for more fixes and improvements to Dart 🔜
