Overview
The usb_device package is a Flutter plugin enabling communication with USB devices on the web. It allows users to initiate sessions, send and receive data, and configure USB devices directly through web browsers that support WebUSB. Designed for device interaction in web applications, it leverages browser-level USB APIs to provide low-level access to connected peripherals. The plugin is particularly useful for developers building web-based tools that interface with hardware such as sensors, controllers, or custom devices. It supports only web platforms and requires user permission for device access.
