advanced_forms just passed 5,000 downloads on pub.dev ππ Big thank you to everyone building forms with it!
Interactive examples, docs and the agent skill πΒ advanced-forms.leancode.co

I'm at @FlutterconWorld Berlin 2026 π You can meet me at @LeanCodePl's booth, so we can talk if any of our open source packages meets your project's needs π
Easy form state management? Robust lint's? Dead code remover? Modern dependency injection? Cool MCPs? Tests? Or maybe just a tasty coffee? We have everything in here πͺ

I ran @LeanCodePl Marionette with @typesafeai Jev.
One sentence: "win the game."
A Flutter game it had never seen. 5 puzzles, rules only on screen. It read the code, flipped the right switches, tapped blue, red, green. π€―
9.7 s. $0.0012. β‘
No LLM involved.
Marionette reads the widget tree and taps, Jev decides π§΅

Hey, your conditional form sections don't have to be a mess :) advanced_forms lets you attach and detach subforms in one call, and the tree π³ nature of the form state means no more ifs in your validators.

Your Product Owner's "small fix" π the day before the client demo: switch form validation from "on submit" to "on unfocus." With @LeanCodePl's advanced_forms that's one line of code :)

Look how little code & effort it took to create a sign in form with validation using advanced_forms πͺ Under a minute of work
We built advanced_forms for the big painful forms, but it's great for the small ones too π advanced-forms.leancode.co

Todayβs magic number is 300! π€―
Weβve just hit two incredible milestones at the exact same time:
β¨ 300 followers right here on X!
β¨ 300,000 monthly downloads on pub. dev!
Itβs great to have you all here. π This, along with a growing number of downloads, gives our Patrol team the ultimate motivation to keep pushing the boundaries of E2E testing.
Thank you for building (and testing) with us! π₯π

π Patrol MCP just changed the game for E2E testing. π Check out all you need to know: leancode.co/blog/patrol-mcp-β¦
Patrol MCP improves the feedback loop, helping you create E2E tests faster while cutting time, tokens, and costs.
The author of Patrol MCP, @oskar_lncd, described:
β¨ How Patrol MCP gives AI visibility and control
β¨ How it compares to other Flutter MCPs (incl. Marionette MCP)
β¨ How to set it up and configure
β¨ What makes it so powerful - with video examples
Read the article & give Patrol MCP a try & share your feedback with us!

Have you tried the Patrol VS Code extension yet? β Now you can run and view tests directly in the UI β no terminal and no need to type the test path every time.
One feature we especially like π
A dedicated βPatrolβ section in Test Explorer
This means:
βοΈ Patrol tests separated from unit tests
βοΈ Easier navigation in large test suites
βοΈ QAs can focus entirely on E2E tests
If you use Patrol for Flutter E2E testing, this can make your workflow much smoother. Read more: leancode.co/blog/patrol-vs-cβ¦

π As you may know, Patrol now supports Flutter Web - but getting there wasnβt as simple as βadding one more platform.β Curious how we actually developed it? π
π Read the full story: leancode.co/blog/patrol-web-β¦
See how we mapped Patrolβs mobile architecture to the Web, what had to change, and the hard decisions along the way. π

π¨ Patrol works with @antigravity! This is how you take Flutter app testing to the next level. βΆοΈ Watch it in action. π
With Patrol working together with Antigravity, you can write great Flutter E2E tests quickly and with minimal effort, not just because the tools work together, but because they make testing efficient by design.

Looking at all the "me too" comments in github.com/flutter/flutter/iβ¦ I'm seeing how many people don't understand how the system obstructions really work on Android/Flutter. Fortunately, some time ago I wrote an article describing it and solving the problem :) leancode.co/blog/mastering-eβ¦
