  "textContent": "**Flutter** is Google's cross-platform UI framework for building applications from a single Dart codebase. Unlike React Native, Flutter does not use platform-native UI widgets; it renders its own widgets pixel-by-pixel via the Skia (and now Impeller) graphics engine. The result is highly consistent visuals across iOS, Android, web, desktop, and embedded.\n\n## Core ideas\n\n  * **Dart.** The language: statically typed, ahead-of-time compiled for release, JIT for dev (hot reload).\n  * **Everything is a widget.** UI is built by composing immutable widget trees; state is held outside in `State` objects.\n  * **Own rendering.** Flutter draws every pixel itself, so an iOS Flutter app does not call UIKit; it shows its own controls.\n  * **Hot reload.** Sub-second rebuild of UI changes during development, a hallmark feature.\n\n\n\n## Where Flutter runs\n\n  * iOS, Android (primary)\n  * Web (limited; canvas/HTML renderers)\n  * macOS, Windows, Linux desktop\n  * Embedded devices (Toyota infotainment, BMW, set-top boxes)\n\n\n\n## Common ecosystem\n\n  * **State management:** Riverpod, BLoC, Provider, GetX, MobX\n  * **Navigation:** go_router, auto_route\n  * **Plugins:** pub.dev hosts the package ecosystem; many platform integrations available\n\n\n\n🔗\n\n**Related Terms**\nReact Native, iOS, Android, Swift, Kotlin\n\n📖\n\n**Further Reading**\nFlutter Is Taking Over",
