Component - Flutter vs React Native comparison

This UI component compares Flutter and React Native by showing two simple buttons labeled "Flutter" and "React Native". When you tap a button, it highlights to show selection, helping you understand how each framework handles UI and interaction.

Widget Tree
Scaffold
├── AppBar
│   └── Text("Flutter vs React Native")

Key Insight
