We just launched ✨the Flutter Add-to-App Portal✨ to guide you through the app migration process!

It helps teams move native iOS and Android apps to Flutter screen by screen, while the app keeps shipping. It covers strategy, architecture, and the integration layer between native and Flutter.

❌ No more guesswork: How do we integrate Flutter into our existing apps? How long will it take, and what will it cost?

✅ All answers are there, based on real native-to-Flutter migrations we've run for our clients.

How long will it take to migrate our native apps to Flutter? How much will it cost? How many people will we need? And will it disrupt our existing product? 🤔

We built #Converge to answer exactly that. 🚀

It turns your iOS and Android codebases into a screen-by-screen Flutter migration plan:
1️⃣ Identifies screens, flows, and shared services.
2️⃣ Pairs iOS and Android screens into waves, simplest first.
3️⃣ Estimates the timeline, cost, and team for each wave.

And it's not just a one-time estimate. Converge updates your plan every sprint, keeping it aligned with your actual migration progress. 💙

One sentence in. A passing E2E test out. 🤯

"Add a Patrol test that rates a talk: open a session, pick 5 stars, confirm Send appears." That's the whole prompt our AI agent got in this video. ✨

E2E tests may eat hours: finding the right keys, running, failing, fixing, repeat. Patrol takes that loop off your hands and does everything quickly.

Here's what the agent did with Patrol from that one prompt: 👇

Our AI agent wrote the test, ran it with Patrol MCP, read the failures, figured out the login flow, and fixed everything until it went green.

Simple prompt, agentic loop, and @patrol_leancode doing the heavy lifting.

Local syntax check while typing, but server call only when user's focus leaves the field? With advanced_forms 0.3.0 that's just few lines of code now :)

What features does your mobile app really need from day one? And which ones could cost you more than expected? 🤔

We prepared 📋 the Checklist of 30 High-Impact Features in Mobile Apps to help you make informed decisions before development begins.

Features are grouped into three layers: ✅ Essentials, ✅ Foundation, and ✅ Accelerators.

AI can build a new screen in seconds. So why bother with a design system? 🤔

Because without one, AI agents improvise. They invent colors, guess at layouts and leave behind code that adds to your technical debt. A design system gives them a closed set of building blocks instead.

📱 iPhone Duo is on sale. Is your Flutter app ready?

It might be with this guide: 👉 https://t.co/ImDq5vjjef

Flutter draws its own widgets, so Apple's automatic adaptation doesn't cover it. Depending on the Xcode you build with, your app may sit in a phone-sized window, stop at the status bar, or run under the camera with navigation stuck at the bottom. 👇

Our #FlutterDev shows how to create seamless cross-screen experiences with our duo_kit package.

@albert_wolszon Nothing makes you want to try a package more than seeing it in action. Nice! Thanks for sharing this example. 💙

[Albert Wolszon 💙💛 @albert_wolszon]

I just tried @LeanCodePl's duo_kit package for one of my apps and it works great! Adding support for both iPhone Duo and Android foldables works like a charm. Having that many layouts to test and maintain also makes use of golden tests really valuable 💯

Still looping requests to get real-time updates from your backend? 🔄 This Thursday, Patryk Kacperski, our Flutter Dev, shows a better way at Full Stack Conf in Sofia.

🎤 Talk title: "Using Server-Sent Events in Flutter"

Showing an LLM-like response or tracking a transaction's status as it's processed? You need real-time updates from your backend. Patryk will explain what Server-Sent Events are, how to build a simple SSE client in Flutter and which ready-made solutions are already out there.

📍 Where: Sofia, Bulgaria

Konnichiwa, Tokyo! This Thursday, @mchudy_, our Senior Flutter Dev, takes the stage at @FlutterKaigi 2026.

🎤 Talk title: "Rethinking Flutter Add-to-App with Inlay"

Official #AddToApp docs and tooling only get you partway there, so most teams end up reinventing the same solutions. Marcin will share what we've learned from integrating Flutter into large native apps for enterprise clients, plus an overview of Inlay, our open-source package.

📍 Where: Tokyo, Japan
📅 When: Thursday, October 29, 17:10–17:40 JST

⚡ New Release: marionette_mcp v0.7! ⚡

Your AI agent can already use your running Flutter app through #MarionetteMCP. Now every run also leaves a report, steps, screenshots, and the agent's own write-up, all in one folder. One line to turn on.

Also new in 0.7.0:
✅ Each look at the screen is about 65% smaller, so long sessions use less context.
✅ Ships its own Agent Skill, so your agent knows the setup
✅ Reaches long lists, bottom sheets and dialogs
✅ Picks the right element, even among identical cards
✅ Switches your running app to dark mode or larger text

Getting your Flutter app ready for iPhone Duo takes one widget. 📱

We just shipped duo_kit - LeanCode's new open-source package for #iPhoneDuo. Wrap your app in ‘FoldScaffold', and your nav bar moves into the side strip as the phone unfolds.

#FlutterDev give it a try. 💙

Seeing a feature ≠ actually trying it 👀

Does the interaction feel right? Is the flow intuitive? Does everything work? Way easier to answer when the whole team can try the app firsthand.

Last week, we introduced #Flitz, our tool for hands-on app reviews in #Flutter teams, and the response blew us away. 🚀 Today, we want to show you how it works in practice.

With Flitz, everyone tries the app on their own phone:
🌟 Engineers get feedback while still in the code.
🌟 Designers test AI-built designs as real apps, no dev needed.
🌟 POs walk the flow and decide the same day.
🌟 QA catches issues before merge.

And the best part? You don't have to change your existing workflow or release process. 💙

4th time at @FlutterconWorld Berlin, and still just as exciting!💙

Last week, we brought a little piece of LeanCode to Berlin again, not just to show what we do, but to share a bit of who we are, too - a team that loves building useful things.

So cool to see you checking out Flitz, Patrol Dispatch, and our 6 open-source packages. Your questions, feedback, and kind words gave us even more reasons to keep building cool stuff. 🚀

Add 8 talks from our team 🎤, lots of Flutter chats, coffee, LeanCode beer, and some great people into the mix… and that's a pretty awesome week.

See you in Berlin next year! 💙

@ABausG @FlutterconWorld @Fiolek_ Yes we do 😎

[LeanCode 💙 @LeanCodePl]

🚀 Day 3 at @FlutterconWorld Berlin is here! Been busy with all the talks over the past two days and haven't heard about Flitz yet?

Come by our booth so @Fiolek_ can show you a quick demo of Flitz (you might also walk away with a brand-new Flitz mug☕).

Flutter makes the developer's coding loop fast. But what about the product team's feedback loop? That's where Flitz comes in.
