Potential Limitations and When Not to Use Flutter

Like any technology, the framework has some limitations and may not always be the best choice. Here is why not to use Flutter.

Potential Limitations of Flutter

• Large application size. Flutter solutions tend to be larger than native apps. This is because it includes a Dart runtime and the Flutter engine within the app, which increases the minimum size.
• Limited third-party libraries. Although Flutter's ecosystem is growing, it still may not have as many third-party libraries as more mature platforms like iOS (Swift/Objective-C) or Android (Java/Kotlin).
• Performance overheads. For most use cases, Flutter's performance is on par with native apps. However, for apps that demand intensive CPU work, such as high-end games or complex calculations, native development may be more efficient.
• Platform conventions. Flutter allows you to create a highly customized UI. Yet, adhering to platform-specific conventions (iOS Human Interface Guidelines or Material Design on Android) can require more effort if you aim for a native look and feel.
• Learning curve. Flutter apps are written in Dart, which is not as widely used as languages like Java or JavaScript. So developers need to learn Dart.

Scenarios When Not to Use Flutter

• Highly customized platform-specific apps. If your app relies heavily on platform-specific features or needs to look and behave exactly like a native app, it might be easier to use the platform's native SDK.
• 3D games or intensive graphics apps. If your app requires sophisticated 3D graphics or game-engine features, a specialized framework like Unity or Unreal Engine could be a better choice. Yet, it is worth mentioning that Flutter is suitable for 2D gaming.
• Ultra-high performance requirements. For apps where performance is critical, native development might provide the edge in speed you need. These apps can be real-time financial trading apps or high-frequency signal processing.
• Existing large codebases. Integrating Flutter into an existing large native codebase can be challenging. It may not bring significant benefits compared to continuing with native development.
• Complex CI/CD pipelines. If your current CI/CD pipeline is highly optimized for native app builds, introducing Flutter might require significant adjustments. Moreover, it might not integrate as smoothly.

Recap of the Benefits of Using Flutter

To summarize, the key advantages:

• Write once, run anywhere allow massive code reuse across iOS and Android.
• Hot Reload boosts developer productivity for faster iteration.
• Customizable widgets and controls to build slick, responsive UIs.
• Access native features like camera, location, and alike via platform channels.
