Need to return an empty widget?

Don't use Container(). It's creates a colored box, checks for constraints, padding, margins, and decoration. It’s "heavy". Use SizedBox.shrink(). It's free.

Small changes add up to better performance. 📱✨

Flutter Performance Tip ⚡️

❌ The Laggy Way: ListView inside a Column with shrinkWrap: true. Result: It renders the whole list instantly. 💥

✅ The Pro Way:Use CustomScrollView with Slivers. Result: True lazy loading. Only builds what is on the screen.

Did you know Flutter might redraw your entire page just to spin a loading icon? 🎨

The Fix: RepaintBoundary
It isolates widgets into separate layers.

❌ Without: Full screen repaints
✅ With: Only loader repaints

Flutter tip time ⚡️

👀 The Scenario: You are using an AnimatedBuilder (or TweenAnimationBuilder) to rotate or fade a complex widget (like a detailed Profile Card).

✅ The Hack: Use the child parameter to build the complex widget once, and only animate the transformation.

Flutter Performance Tip 🚀

Building a ListView where every item has the same height?

Don't let Flutter guess the size! Use itemExtent.

It tells the scroll view exactly how big items are, skipping expensive layout calculations during scrolling. 📉

Smoother scrolling, less jank.

One line of code to instantly improve your Flutter app's scrolling performance. ⚡️

If your source image is 3000px but your widget is only 300px, use cacheWidth.

Why?

It reduces decode time and memory usage.
Your users (and their batteries) will thank you. 🔋

I found this random VS Code extension and it’s actually gold. 🏆

Instead of reading raw text, it visualizes your JSON as a flowchart. Makes debugging complex data so much faster.

Highly recommend grabbing it: 👉 marketplace.visualstudio.com/items?itemNa...

Ever wonder why the Flutter linter begs you to use const? Here is the proof. 👇

I triggered setState 50 times.
🔴 Non-const Text: Rebuilt 50 times.
🟢 Const Text: Rebuilt only 2 times.

This tiny keyword saves app from unnecessary work.
Stop ignoring! ⚡️

🚀 Speed Up Your Flutter Apps! 🚀

Want to load heavy features only when needed?

Use Dart’s deferred keyword to lazy-load parts of your app!

🔹 Faster startup!

Try it for big features, maps, or anything not needed right away.

🚀 Built payment workflow using Kotlin's structured concurrency.

Three checks in parallel: validation, fraud, inventory. ✅

All succeed → charge on Dispatchers.IO
Any fail → cancel safely 🛡️

🚀 CMake + Flutter = Power! 🛠️

CMake compiles C/C++ libraries, bridging Flutter with native code.

💡 What:
• Compiles to .so/.dll
• Manages dependencies
• Integrates

🌍 Support: Android, Windows, Linux, macOS

🔧 Flow: C++ → CMakeLists → FFI

💻 Tips:
• Check
• Debug

🚀 Kotlin Tips ✨

**Null Safety**
• Use sealed over nullable
