Technical Deep Dive: Why Flutter Outperforms Other Frameworks
You’ll notice that most blogs will cover the beginner friendly jargon. If you want to outrank your competitors, you need to know the engineering side of Flutter. Below is a brief comparison between Flutter and other popular frameworks:
| Aspect | Flutter | React Native | Kotlin Multiplatform |
| Rendering | 60 to 120 frames per second (FPS) | 45 to 50 frames per second (FPS) | 57.2 to 119 frames per second (FPS) |
| Code Sharing | Same code can be used for iOS, Android, and Web | Platform tweaks are often needed | Separate UI, different codes are required. |
| Iteration | Fastest hot reload | Less stable, slower | No hot reload feature |
| Startup Time | AOT = fast native-like startup | JS interpretation slows startup | Platform dependent |
| Animations | Direct GPU access | Okaish | Native component limitations |
In terms of design, Flutter takes the crown. It doesn’t use a JavaScript bridge and complies directly in the ARM native code.
Although React Native has improved its speed and creating animations, it hasn’t eliminated its native communication overhead. Similarly, with Kotlin Multiplatform, its UI consistency and development speed isn’t that great.
1. Lower Cost of Maintenance
Maintaining multiple codebases (iOS + Android + web) is expensive. Flutter will reduce the overall cost. That means you can relocate your budget better.
How this impacts your business:
- Fewer engineers required for multi-platform delivery
