Overview
The web_socket_channel package provides a cross-platform API for WebSocket communication, wrapping StreamChannel to enable consistent WebSocket handling across platforms. It offers a unified interface for establishing and managing WebSocket connections, abstracting underlying platform differences. Built on top of Dart's StreamChannel, it supports bidirectional data flow through streams, making it ideal for real-time applications. The package is designed for use in Flutter apps targeting Android, iOS, Web, macOS, Windows, and Linux, ensuring seamless integration with existing stream-based architectures.
