Optimize FlatList for Fast React Native Apps

Found a critical bug in production? ⁉️ Don't panic. Waiting days for App Store or Google Play reviews is a thing of the past. I put together a quick deck on how Flutter Shorebird brings OTA (Over-The-Air) Code Push directly to your apps. 🚀 Fix bugs in minutes, bypass the wait, and keep your users happy-all while staying 100% store compliant. 🌟 Check out the slides below! Have you tried Code Push yet? Let's discuss!👇 source: https://shorebird.dev/ #Flutter #MobileDevelopment #Shorebird #CodePush #Dart

Did you know? Every app you build in WeWeb is a Single Page Application (SPA) 🚀 Here's what that means for your users: when they navigate between pages, the browser doesn't reload everything from scratch. It only updates the content that actually changed. Your sidebar stays put. Your navbar stays put. Scroll position stays put. Only the main content area swaps. That's why your published app feels fast and smooth between pages ✨ (Good to know: the editor reloads pages for preview purposes, but your published app gets the full SPA experience.) Did you know this about your app? 👇

Stop waiting for Play Store approvals just to tweak a UI element. With Jetpack Compose Remote, you can deliver UI updates directly from the server while keeping native Android performance. Build once, push UI changes instantly — no app update required.

Day 13/20 Today we learnt about navigation in Flutter. Navigation allows you to move between different screens or routes in your app. Understanding how navigation works is fundamental for building apps with multiple screens or dynamic content. To switch to a new route, use the Navigator.push() method. The push() method adds a Route to the stack of routes managed by the Navigator. By using the Navigator.pop() method it closes the second route and return to the first route The pop() method removes the current Route from the stack of routes managed by the Navigator. #GIT20DayChallenge #AfricaAgility

The simplest change I made that immediately improved my FastAPI app: Using async def for every route. That's it. FastAPI is asynchronous by nature. Using async def means your app can handle multiple requests at the same time without blocking. The function below processes a request while the event loop stays free to handle everyone else: Versus the sync version, which holds up the entire queue until it's finished. One keyword. Completely different behavior under load. The tools were always there. I just refused to use them.

If you're a beginner in React and want to solidify your fundamentals, Here are some projects you can build. - Counter app - Todo list - Weather app - Calculator - Digital Clock - Stopwatch/Timer app - Quote generator - Expense tracker - Form validation app - Movie app - Quiz app - Currency converter - Typing speed test - Joke generator

🚀 ContentObserver in Android ContentObserver — a powerful component that lets your app listen for changes in a ContentProvider. With ContentObserver, you can automatically react when data changes (like media files, contacts, or messages) without constantly polling the system. It’s especially useful when working with MediaStore to detect new photos or videos in real-time. Implementing it properly improved my app’s responsiveness and reduced unnecessary background work — making the UI feel instantly updated. Small components, big impact. 💡 #Android #JetpackCompose #AndroidDevelopment #Kotlin #MobileDevelopment

🚀 Small Flutter Performance Tip One thing I’ve learned after building multiple Flutter apps: 👉 Most performance issues are caused by unnecessary widget rebuilds. A simple fix that works surprisingly well: > Use const widgets wherever possible > Avoid rebuilding the entire screen for small changes This alone can make your app feel significantly smoother. Flutter is fast by default — we just need to use it right. #Flutter #MobileDevelopment #Performance

Day 10/20 Introduction to Navigation Today I learned how apps move from one screen to another. Flutter uses something called Navigator for this. For example: Navigator.push() This allows a user to open a new screen. And when they go back: Navigator.pop() It closes the current screen. This is how most apps allow users to move through different pages. #GIT20DayChallenge #AfricaAgility

Some tools you use. Others you build. The ones you build, actually fit how your team works. That’s the difference. Sferal lets you turn a simple description into a working internal app. No code. Just dialogue.
