flutter_usb_serial

Flutter USB serial transport for Android and DriverKit-enabled iPadOS.

Platforms

Android uses usb-serial-for-android and the normal Android USB permission flow.
iPadOS 16+ uses Swift Package Manager and a user client exposed by a USBDriverKit extension embedded in the host app. DriverKit USB support is available only on iPads with an M-series chip.

The package contains the SwiftPM client plugin, not a reusable pre-signed DriverKit extension. Apple provisions USB transport entitlements to the host app and driver for a specific USB vendor. The host app must:

Embed a DriverKit extension whose IOUserClass is DaliMasterEspressifUsbDriver, or adapt the client service name.
Add com.apple.developer.driverkit.communicates-with-drivers to the app.
Sign the extension with com.apple.developer.driverkit and a com.apple.developer.driverkit.transport.usb entitlement approved for its USB vendor ID.
Enable Swift Package Manager integration for Flutter iOS plugins.

Call FlutterUsbSerial.isDriverAvailable() during startup before showing a USB transport. It returns true only when a compatible driver service is loaded.

The DaliMaster host implementation is deliberately restricted to Espressif vendor ID 0x303A and the USB Serial/JTAG interface. Serial parameter and modem line methods are accepted for API compatibility; the ESP USB Serial/JTAG bulk transport does not use UART baud or line coding.
