4. Programming Language: Dart vs JavaScript/TypeScript
One of the main differences between Flutter and React Native is the programming language used.
Flutter Uses Dart
Flutter applications are written primarily in Dart.
Dart provides features such as:
- Static type checking
- Object-oriented programming
- Asynchronous programming
- A language designed to work with Flutter's development model
Flutter's official documentation provides language and framework resources for developers learning Dart and Flutter.
React Native Uses JavaScript or TypeScript
React Native uses React and JavaScript, and many projects use TypeScript.
This can be useful for teams that already have experience with:
- React
- JavaScript
- TypeScript
- npm packages
- Frontend development
- Web application architecture
React Native's official documentation explains how developers use React concepts to build native mobile applications.
What Does This Mean for a Business?
The existing skills of the development team can influence onboarding, productivity, hiring, and maintenance.
A team with significant React experience may already understand many concepts used in React Native. A team experienced with Flutter and Dart may be familiar with Flutter's widget and application architecture.
5. UI and User Experience
UI implementation is one of the most visible differences between the frameworks.
Flutter UI
Flutter uses its own widget system and rendering approach. This gives developers control over how many interface elements are drawn and styled.
Flutter provides Material and Cupertino widgets, along with tools for creating custom interfaces.
Flutter can be useful for applications that need:
- Consistent custom branding
- Reusable interface components
- Complex custom layouts
- Rich animations
- Similar visual design across platforms
React Native UI
React Native uses React components that connect with native platform UI components.
This approach can help developers create interfaces that use platform-specific controls and interactions.
However, platform differences may need to be considered when building and testing the application across Android and iOS.
UI Comparison
| UI Requirement | Flutter | React Native |
|---|---|---|
| Custom branded interface | Supported through Flutter widgets | Supported through React components and styling |
| Platform-specific appearance | Can be designed and adapted for each platform | Can use native platform components |
| Shared visual components | Shared widgets can be used across platforms | Shared components can be used where platform behavior permits |
| Complex animations | Flutter provides animation APIs | React Native supports animation approaches through its ecosystem |
| Consistent visual presentation | Flutter controls much of its own rendering | Native component behavior can vary by platform |
The suitability of either approach depends on the required design, platform conventions, accessibility, and implementation quality.
6. Performance: Flutter vs React Native
Performance is often discussed when comparing cross-platform frameworks, but it should be assessed in the context of the actual application.
Important performance factors include:
- Rendering
- Animations
- Network requests

Flutter Performance
Flutter uses its own rendering architecture and supports compiling mobile applications to native machine code. Its architecture is designed to support custom interfaces and multi-platform development.
React Native Performance
React Native connects JavaScript application logic with native platform functionality. Its architecture and performance characteristics depend on the React Native version, native integrations, JavaScript workload, and application design.
How Should Businesses Compare Performance?
Rather than relying only on generalized claims, evaluate the frameworks using the actual requirements:
- Build a representative prototype.
- Test on the devices your users are likely to use.
- Measure startup time and screen transitions.
- Test scrolling and animations.
- Measure memory and battery behavior.
- Test network and API performance.
- Test the integrations the production application will require.
This provides more meaningful evidence for a particular project than a framework-wide performance claim.
