Audioplayers

audioplayers is an open-source audio playback library designed for Flutter applications. It provides a cross-platform plugin that exposes a unified API for playing audio from various sources, including network streams, bundled assets, and local files.

With audioplayers, developers can control playback through operations such as play, pause, stop, and seek, as well as adjust volume and playback rate and configure looping or background playback. The library supports multiple concurrent players, enabling scenarios where several audio streams are managed independently. It also offers event streams and callbacks for monitoring playback state, duration, position, buffering, and errors, which can be used to drive user interfaces and analytics. In addition, it can handle preloading or caching behavior and work with platform-specific features like media controls and notifications.

On the web, audioplayers relies on browser APIs, while on mobile and desktop it delegates to native platform components. The API is designed to be accessible from Dart code, with methods to set sources and perform common actions, as well as streams to observe changes. Developers typically add the package to pubspec.yaml, instantiate an AudioPlayer, set a source, and issue playback commands while listening to state streams for UI updates.

audioplayers is widely used in Flutter projects and is maintained by an open-source community. It competes with other audio libraries such as just_audio, which offer alternative architectures and features. The project emphasizes simplicity, portability, and a consistent API across platforms.
