qrcode_barcode_scanner 4.0.0

Plugins to manage the reading of QR code or barcode from an external device as a keyboard.

CHANGELOG

4.0.0

Scanning correctness

• Fix scanned values being corrupted on non‑US keyboard layouts. Characters are now decoded from the physical key of the event through a US QWERTY table, which is what HID scanners actually emit, instead of the character the operating system reports. On an Italian layout this fixes = being read as ì, / as - and + as ], which silently broke every base64 payload.
• Add ScannerKeyMapping and the keyMapping parameter to opt back into the previous behaviour (ScannerKeyMapping.platformCharacter) for scanners that are programmed with the same layout as the device.
• Deliver the scan immediately when the scanner sends its Enter/Tab suffix instead of waiting for the idle timeout, and stop appending that suffix to the value. Configurable through submitOnTerminator.
• Only handle key down events, so a scanner that reports characters on key up can no longer duplicate them.
• Add the scanDelay and ignoreWhenTextInputFocused parameters, and a public flush() to deliver a partial scan on demand.
• dispose() is now idempotent and cancels the pending scan.

Migration to the current Flutter toolchain

• Require Dart ^3.8.0 / Flutter >=3.32.0.
• Android: compileSdk 36, minSdk 24, Java 17, AGP 8.11.1, unconditional namespace, dependencies moved out of the android block.
• Example app: Gradle 8.14.3, AGP 8.11.1, Kotlin 2.2.20, flutter.* SDK versions, rootProject.layout.buildDirectory instead of the removed buildDir.
• CI now builds against a current Flutter and runs the test suite.

Breaking changes

• The Android package moved from com.example.qrcode_barcode_scanner to com.francescodema.dev.qrcode_barcode_scanner. The pub.dev package name is unchanged, and the Flutter tool regenerates GeneratedPluginRegistrant.java automatically, so no action is needed unless you referenced the plugin class by its fully qualified Java name (manual registration in an add-to-app host, or a ProGuard/R8 keep rule).
• DelayedActionHandler moved to lib/src/; it is an internal utility and is no longer importable from package:qrcode_barcode_scanner/delayed_action_handler.dart.
• Values are decoded through the US layout by default. If your scanner is programmed for a non‑US layout, pass keyMapping: ScannerKeyMapping.platformCharacter.
