How do React Native and Flutter differ in their approach?

React Native uses JavaScript to bridge to native UI components, making it ideal for web-focused teams, while Flutter uses the Dart language and a custom rendering engine for highly consistent, high-performance UIs.

What is the primary benefit of cross-platform development?

The primary benefit is efficiency through 'write once, run anywhere' logic, allowing teams to share up to 90% of their codebase across iOS and Android, which significantly reduces development time and costs.

Is it possible to achieve 100% code sharing?

While 100% is technically possible for very simple apps, high-quality applications usually require 10-15% platform-specific code to handle native integrations, navigation patterns, and platform-specific UI conventions.

When should I choose Native development over a cross-platform framework?

Native development is preferred for performance-critical applications like high-end games, AR/VR apps, or applications requiring extremely deep integration with specific hardware features.

Mobile Development

Guides the evaluation and implementation of multi-platform application strategies using shared codebases for iOS, Android, and web.

This skill provides a comprehensive framework for building applications across multiple operating systems using unified codebases, helping developers navigate the critical trade-offs between native, cross-platform (Flutter/React Native), hybrid, and PWA approaches. It offers structured guidance on requirement analysis, architecture design for platform isolation, and performance optimization to ensure efficient development without sacrificing user experience. By implementing these methodologies, teams can maximize code reuse—often reaching 85-90%—while maintaining adherence to platform-specific design conventions like iOS Human Interface Guidelines and Android Material Design.
