flutter_zpl_printer_testing library

Test-only exports. Consumers import this instead of package:flutter_zpl_printer/flutter_zpl_printer.dart when they need public test doubles (e.g. in widget or integration tests).

The classes here are intentionally public but not exported from the main barrel — they have no production use.

Classes

FakeUsbPlatform

In-memory UsbPlatform for tests.

UsbDeviceRecord

One USB device returned by UsbHostApi.enumerate.

UsbEnumerateFilter

Filter passed to UsbHostApi.enumerate.

UsbOpenResult

Result of a successful UsbHostApi.openForFfi call. The Dart FFI layer takes over I/O from here.

UsbPlatform

Abstract seam between high-level USB classes (UsbConnection, UsbDiscovery) and the concrete MethodChannel + FFI backend.
