Flutter(クロスプラットフォーム)とネイティブ(iOS/Androidアプリを別々に開発)の選択は、開発コスト、パフォーマンス、プラットフォーム機能、チームスキルなどのトレードオフを伴う重要な決定です。各アプローチが適切な場面を理解することは、判断力のある技術的意思決定を反映しています。
Flutterの利点(クロスプラットフォーム)
✓ ONE codebase for iOS + Android (+ web/desktop) → less development/maintenance cost
✓ FASTER development (hot reload, shared code); faster time-to-market
✓ Consistent UI across platforms; good performance (compiled)
✓ Smaller team can target multiple platforms
→ Great for: most apps, MVPs, startups, apps wanting multi-platform efficiently,
consistent branding
ネイティブ開発の利点
✓ FULL access to platform features/APIs immediately (newest OS features day one)
✓ Best possible performance for demanding apps (games, heavy graphics, AR/VR)
✓ Most native look/feel and platform integration
✓ Mature, platform-specific tooling and large native talent pools
→ Great for: performance-critical apps, deep platform integration, apps using cutting-edge
native features, when you have separate iOS/Android expertise
