Flutter 🎂
What started as an experimental project called "Sky" has evolved into the most popular cross-platform framework in the world.

Here’s the short version of how it changed over the years:

1. Early Flutter introduced these core ideas:
> Render everything with Skia
> Dart’s fast compile times and hot reload, providing devs with an insanely tight feedback loop.

2. Flutter 1.0 (2018)
> first official release
> stable iOS + Android support
> early patterns for declarative UI

3. Flutter 2 (2021)
> web became stable
> desktop matured
> sound null safety improved reliability

4. Flutter 3 (2022)
> desktop became stable
> Material 3 landed
> Impeller renderer debuted to fix shader jank

5. Recent Years
> Impeller became the default
> Wasm support improved web startup times
> Thread-merge work simplified Flutter’s core pipeline
> Generative UI tools

Happy Birthday, Flutter.
Another year older, still evolving, still fun to work with

Channel summary for 2025

🎨 Creativity is the Art of "Cheating"

Junior devs try to process everything perfectly. Senior devs use illusions.

✅ Instagram starts uploading your photo while you are still typing the caption, just so the "Post" button feels instant later.
✅ Video Games don't render the world behind the player's back.

Creativity isn't always about writing faster algorithms. It's about finding the brilliant shortcut that tricks the user's brain into thinking your app is magic.

If you can't optimize the code, optimize the perception.

🛑 Stop Killing Your Flutter App's Performance

Your code might work, but is it fast? 📉 Slow apps get uninstalled. Uninstalled apps make $0 revenue.

Here are the Top 5 silent killers in Flutter (and how to fix them):

1. The build() Method Trap 🪤
Never put complex logic or HTTP requests inside your build() method. Flutter calls this method constantly.
✅ Fix: Move logic to initState or your State Management (Bloc/Riverpod).

2. Ignoring the const Keyword 🧱
If a widget doesn't change, tell Flutter! Using const tells the framework:

"Don't waste time rebuilding this."

✅ Fix: Enable the prefer_const_constructors linter rule.

3. The Opacity Widget Mistake 👻
Animating the Opacity widget is incredibly expensive because it redraws every frame.
✅ Fix: Use FadeTransition or AnimatedOpacity instead. It’s GPU-accelerated and buttery smooth.

4. Oversized Images 🖼
Loading a 4MB image into a 100x100 avatar circle? You are choking the memory.
✅ Fix: Use cacheWidth and cacheHeight in Image.network to resize it before it enters memory.

5. ListView vs ListView.builder 📜
Using a standard ListView renders every item at once. If you have 1,000 items, you will crash.
✅ Fix: Always use ListView.builder. It only renders what is currently visible on the screen.


💡 Entrepreneur Tip:
Users judge your brand by your app's speed. Amazon found that every 100ms latency cost them 1% in sales. Performance isn't just code; it's profit.

🥊 War Wednesday: The King of State Management?

It’s 2025. The debate isn't over.

If you are starting a large-scale enterprise app today, which soldier are you taking into battle?

Be honest. No "it depends." 👇

🥊 War Wednesday: The Founder's Dilemma

You have a killer app idea. 💡
You have exactly 30 days to launch before a competitor does.

You can only pick one strategy. Which one wins? 👇

(I know which one makes more money...)

📋 SaaS Idea: Digital Forms for Local Biz

Walk into a mechanic shop, a dentist, or a gym. Do they hand you a clipboard and paper? That is your opportunity.

The Idea: A tablet app (Flutter runs great on cheap Android tablets) for client intake forms.

The Pitch:

✅ "Stop typing customer data manually from paper."

✅ "My app saves the form directly to your Google Sheets/CRM."

Charge: X Birr /month.

Why it works: You don't need 1,000 users. You need 5 local businesses to make a side income.
