posprinter_usb_android 1.0.0

Android USB host transport for ESC/POS thermal receipt printers: device discovery, the USB permission handshake and raw bulk-transfer printing.

1.0.0

First release of posprinter_usb_android, an Android-only USB fork of flutter_pos_printer_platform_image_3 1.2.4 (MIT, © 2022 Gustavo Morales and contributors).

Keeps the maintained Android USB fixes from the fork it is based on:

• A USB permission handshake that completes only once Android answers the dialog, instead of resolving connectPrinter before the grant.
• Android 13+ IntentFilter receivers registered with Context.RECEIVER_NOT_EXPORTED, and a cancelled stale PendingIntent from a previous process so the permission dialog cannot reappear over the launcher.
• USBStatus.attached events so the Dart side can reconnect immediately on replug, and USBStatus.none on detach.
• Chunked bulk writes that respect the endpoint's maxPacketSize, stop on the first failed chunk and close a stale endpoint so the next attempt re-opens it.

Reduced to the Android USB transport:

• Removed the iOS and Windows implementations (and the vendored libGSDK.a).
• Removed the Bluetooth, BLE and network (TCP) transports and the Star/TSPL/ ESC-POS generator surface. The package now depends on nothing but Flutter.
• Removed the Bluetooth, Bluetooth-admin and location permissions from the plugin manifest, so they are no longer merged into the host app.
• PrinterType now only has usb, and PrinterManager only exposes the USB transport.
• Converted the Android build script to build.gradle.kts and migrated it to AGP built-in Kotlin. The module no longer applies the Kotlin Gradle Plugin itself, which clears Flutter's "plugins that apply KGP" warning.
• Minimum supported version is now Flutter 3.44 / Dart 3.12, required by kotlin.compilerOptions.
