Flutter is a mobile app SDK to help developers and designers build modern mobile apps for iOS and Android.
- Fast development - Flutter's "hot reload" helps you quickly and easily experiment, build UIs, add features, and fix bug faster. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android.
- Expressive UIs - Delight your users with Flutter's built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness.
- Access native features and SDKs - Make your app come to life with platform APIs, 3rd party SDKs, and native code. Flutter lets you reuse your existing Java, Swift, and ObjC code, and access native features and SDKs on iOS and Android.
