Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's, and tomorrow's, mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
See the getting started guide for information about using Flutter.
The Flutter animation system.
Flutter widgets implementing the current iOS design language.
Core Flutter framework primitives.
The Flutter gesture recognizers.
Flutter widgets implementing Material Design.
The Flutter painting library.
Simple one-dimensional physics simulations, such as springs, friction, and gravity, for use in user interface animations.
The Flutter rendering tree.
The Flutter Scheduler library.
Platform services exposed to Flutter apps.
The Flutter widgets framework.
Support for asynchronous programming, with classes such as Future and Stream.
Classes and utilities that supplement the collection support in dart:core.
Encoders and decoders for converting between different data representations, including JSON and UTF-8.
Built-in types, collections, and other core functionality for every Dart program.
Interact with developer tools such as the debugger and inspector.
File, socket, HTTP, and other I/O support for server applications.
Concurrent programming using isolates: independent workers that are similar to threads but don't share memory, communicating only via messages.
Mathematical constants and functions, plus a random number generator.
Lists that efficiently handle fixed sized data (for example, unsigned 8 byte integers) and SIMD numeric types.
Built-in types and core primitives for a Flutter application.
Testing library for flutter, built on top of
Provides API to test Flutter applications that run on real devices and emulators.
This library provides a Dart VM service extension that is required for tests that use
package:flutter_driverto drive applications from a separate process, similar to Selenium (web), Espresso (Android) and UI Automation (iOS).
