Flutter Basics Series: Stateless vs Stateful Widgets

Flutter Preview — A Small Feature That Makes a Big Difference 🚀 While exploring Flutter recently, I discovered the Flutter Preview feature and honestly, it’s amazing ✨. It allows developers to instantly see how the UI will look without running the full app again and again. This makes UI development much faster and smoother. Features like this really improve the developer experience and help us focus more on building great interfaces instead of waiting for builds ⏱️. A big thanks to Google and the Flutter team for creating such a powerful and thoughtful feature for developers 👏. #Flutter #Google #Preview #MobileAppDevelopment #AppDevelopment #DeveloperTools

Most Flutter apps are badly architected. Not because Flutter is limited. But because developers treat it like a UI framework. Flutter is not just widgets. If your app has: • Business logic inside widgets • setState controlling entire screens • API calls inside UI files • No clear separation of concerns You don’t have an app. You have technical debt with animations. Scalability is not added later. It’s designed on day one. Architecture > Packages Structure > Shortcuts Systems > Screens Flutter is powerful. But only if you build it like a system. #Flutter #FlutterDev #MobileArchitecture #CleanArchitecture #AppDevelopment #SoftwareEngineering

🚀 Widget Rebuild Analysis in Flutter Ever felt your app getting slower for no obvious reason? 🤔 Unnecessary widget rebuilds might be the hidden culprit. Let’s break it down simply 👇 🔍 How to detect unnecessary rebuilds? Flutter gives you a couple of handy ways: 1️⃣ debugPrintRebuildDirtyWidgets This is the quickest way to see what’s rebuilding. Just enable it in your app, and Flutter will log every widget that rebuilds in the console. 👉 If you notice widgets rebuilding too often without any state change — that’s your red flag 🚩 --- 2️⃣ Flutter Inspector (DevTools) Prefer visual debugging? This one’s for you. Use the Flutter Inspector to: - Track widget rebuilds in real-time - Highlight frequently rebuilding widgets - Understand your widget tree better 👉 It helps you see the problem instead of just reading logs 👀 --- 💡 Pro Tip Not every rebuild is bad. Flutter is optimized for it. But unnecessary rebuilds = wasted performance. ✔️ Keep widgets small ✔️ Use const where possible ✔️ Manage state wisely --- ✨ Final Thought Performance isn’t just about writing code — it’s about understanding what your UI is doing behind the scenes. Start observing rebuilds, and you’ll start building faster apps 🚀 #Flutter #MobileDevelopment #AppPerformance #SoftwareEngineering #Developers

One thing I’ve noticed while building mobile apps with Flutter is that many developers try to build everything from scratch. But high-quality apps are often built by using the right widgets and packages, not by reinventing the wheel. Flutter already provides powerful widgets that make apps feel modern, responsive, and production-ready. Some that I frequently rely on: • FutureBuilder / StreamBuilder – for handling real-time and async data • Hero & AnimatedContainer – for smooth, professional animations • ListView.builder – for scalable and optimized UI rendering And when it comes to packages, choosing the right ones can significantly speed up development: • provider / riverpod – clean and scalable state management • dio – powerful networking and API handling • go_router – modern navigation and routing • cached_network_image – optimized image loading Great apps are not just about UI. They’re about performance, maintainability, and scalability. The real skill of a Flutter developer is knowing which tools to use and when to use them.

Most Flutter apps fail because of poor architecture — not poor UI. After working on multiple production apps, I’ve noticed 3 common mistakes: 1️⃣ No proper state management Developers start with setState everywhere — and the app becomes messy as it grows. 2️⃣ API logic mixed inside UI Business logic inside widgets makes testing and scaling difficult. 3️⃣ No performance optimization Ignoring lazy loading, const constructors, and rebuild control causes frame drops. If you’re building a Flutter app, these things matter more than animations. A clean architecture: ✔ improves performance ✔ makes future updates easier ✔ reduces bugs ✔ saves development cost long term If you're planning a Flutter app or facing performance issues, feel free to connect. #Flutter #MobileDevelopment #AppDevelopment #TechLeadership #SoftwareArchitecture

If you’re learning Flutter, here’s something no one tells you: Your first 5 apps don’t matter. They won’t be perfect. They won’t be scalable. They won’t impress anyone. But they will teach you: • How widgets really work • Why your UI keeps rebuilding • How to debug properly • How to think like a developer Most beginners quit because their first app isn’t “portfolio ready”. Build messy. Learn fast. Improve consistently. That’s how real progress happens. #Flutter #FlutterDeveloper #MobileDevelopment #Dart #BuildInPublic #Developers #TechCareers #Learning

🚀 Mastering TextFormField in Flutter Built a simple yet powerful guide to understand how form inputs work in Flutter apps. 🔑 Key takeaways: • Creating user-friendly input fields • Adding validation for better UX • Handling passwords securely • Managing input using controllers This is a fundamental concept for building real-world apps like login, signup, and forms. 💡 Small concepts → Big impact in app development Currently exploring Flutter + Firebase to build scalable applications. #Flutter #AppDevelopment #MobileDevelopment #FlutterDev #Firebase #Coding #DeveloperJourney #UIUX #AndroidDevelopment

Flutter is incredibly powerful, but small mistakes can silently hurt app performance. Here are a few common ones I’ve noticed while building production apps: - Rebuilding the entire widget tree unnecessarily Wrapping large UI sections with reactive builders (Obx, StreamBuilder, FutureBuilder) can trigger frequent rebuilds. Always keep rebuild scopes as small as possible. - Ignoring const widgets Using const wherever possible allows Flutter to skip rebuilds. It’s a small keyword, but it makes a real difference. - Heavy work in the build() method build() can run many times. Expensive calculations, API calls, or parsing inside it will slow down the UI. - Unoptimized ListViews Using ListView(children: []) for large lists instead of ListView.builder() increases memory usage and hurts performance. - Large images without optimization Displaying large images without compression or caching can cause frame drops and memory issues. Flutter usually performs well by default. But performance problems often come from how we structure widgets and manage state. The good news? Most of these issues are easy to fix once you notice them.

Mobile development eventually moves beyond building screens. In Flutter projects, long-term success usually comes from combining: • UI structure • backend thinking • system design into a single workflow. Apps that scale well tend to share quiet traits clean structure, predictable state, and clearly defined responsibilities. Flutter works best when treated as part of a system, not just a UI framework. #Flutter #mobileApps

🚀 I just published a new article about PercentagesWithAnimationCompose, a library I created for building animated percentage indicators in Jetpack Compose. In the article, I explain how to set up the library and customize the indicators to fit different UI needs in Android apps. If you're working with Jetpack Compose and want an easy way to add animated percentage visuals to your UI, this might be useful.
