Flutter Development: Focus on Clean Code and Architecture

Real Dev or Vibe Coder? Let's test it. Most Flutter developers use Navigator methods every single day but half of them pick the wrong one after login and silently leak memory in production. I'm starting a new SERIES where I'll drop 3 Flutter statements every day. 2 are correct. 1 is wrong. If you can spot the wrong one, you're thinking like a real developer not a vibe coder. Swipe through the carousel and drop your answer in the comments 👇 Let's see how many real devs are in here. #flutter #flutterdev #dartlang #flutterdeveloper #mobiledevelopment #mobileappdevelopment #appdevelopment #softwareengineering #softwaredeveloper #programming #coding #developercommunity #techcommunity #flutterapp #crossplatform #opensource #learntocode #codingtips #developerlife

🚨 Circular Dependency in NestJS: The Silent Architecture Killer ❌ Nest can't resolve dependencies of the XService (?). Please make sure that the argument YService is available in the current context. It compiles fine… but at runtime it breaks your app with unresolved dependencies, exposing hidden coupling in your design. It’s not just a NestJS issue — it’s a sign your services are too tightly connected and need better separation of concerns. #NestJS #NodeJS #BackendDevelopment #SystemDesign #SoftwareArchitecture #CleanCode #TypeScript #Microservices #WebDevelopment #Programming #Developers

I published my first article on Medium. It's about something every Flutter developer does 10 times a day — setState(). But do you actually know what happens after you call it? I didn't. Not fully. So I went deep into Flutter's rendering pipeline and wrote everything down. The article covers: → The 5 phases Flutter runs every single frame → The 3 trees Flutter maintains (Widget, Render, Layer) → Why jank happens and exactly which phase causes it → How const widgets skip the entire build phase → What RepaintBoundary actually does under the hood This is the article I wish had existed when I started learning Flutter internals. Link in the comments 👇 Would love to hear your feedback — especially from senior Flutter devs who know this stuff better than me. #Flutter #FlutterDev #Dart #MobileDevelopment #FlutterTips #Medium #RenderingPipeline #Programming #AndroidDev

Flutter Development Tip: Stop Rebuilding from Scratch Every Time One of the biggest mistakes developers make is overcomplicating fixes. Before restarting your whole project, try this simple flow: ✔️ flutter clean ✔️ flutter pub get ✔️ Restart IDE ✔️ Check recent changes 70% of Flutter issues are cache or dependency related — not actual code bugs. Smart debugging saves hours of frustration. #Flutter #MobileDevelopment #Programming #Debugg

Stop writing code like this ❌ It looks right… but it’s completely wrong. This is how small mistakes silently break your app. Clean code isn’t optional — it’s a responsibility.

🚨 You’re slowing down your Node.js app without realizing it… Most developers write async/await like this 👇 Clean? Yes. Fast? ❌ 👉 Problem: Each await blocks the next one → Total time = sum of all delays ⏳ 👉 Fix: Run independent tasks in parallel ⚡ ⚡ Result: • Faster APIs • Better user experience • Improved performance 🔥 Golden Rule: If tasks don’t depend on each other → run them together. 📌 Save this — 90% of developers ignore it. 💬 Be honest… are you still writing sequential awaits? --- #NodeJS #JavaScript #BackendDevelopment #AsyncAwait #PerformanceOptimization #WebDevelopment #SoftwareEngineering #Programming #Developers #Coding #TechTips #LearnToCode #100DaysOfCode #CodeNewbie #DevCommunity

Just published a new blog post on Managing Component State with React It shows you how to use the useState Hook to handle state in functional components and make UIs that change and respond to user input. I've also added simple code examples to help you understand how state works in real-world React apps. If you're learning React, this is a must-know concept! 👉 Read more: https://lnkd.in/gcCEDNah #ReactJS #JavaScript #WebDevelopment #Frontend #Programming #SoftwareEngineering

How big should a single file be in Flutter? 🤔 Are you writing 500+ or even 800+ lines in a single Flutter file? 🤔 That might be slowing you down more than you think.

⚛️ useEffect is simple… until it breaks your app 💀 Most React devs think they understand useEffect… But misuse it → and your app turns into a bug factory 😵💫 Here’s what you really need to know 👇 ⚡ useEffect = Side effects handler (API calls, timers, DOM updates) ⚡ No dependency array? Runs on EVERY render → performance killer 🚨 ⚡ Empty dependency array [] Runs only once (on mount) — perfect for API calls 🔥 ⚡ Dependency-based execution Runs when values change → controlled updates 🎯 ⚡ Cleanup function = underrated hero Prevents memory leaks & unwanted behavior 🧹 ❌ Beginner: “useEffect works somehow” ✅ Pro: “I control when & why it runs” 💬 React isn’t hard… Understanding lifecycle is the real game 📌 Save this before your next React project #ReactJS #useEffect #Frontend #WebDevelopment #JavaScript #Coding #Developers #Programming
