Caps Lock error on Android 6 #28

First, very awesome library. Im using it on a Android device with an external Barcode scanner. Every time I scan something, im getting this error Exception caught by services library ══════════════════════════════════ Attempted to send a key down event when no keys are in keysPressed. This state can occur if the key event being sent doesn't properly set its modifier flags. This was the event: RawKeyDownEvent#82bce(logicalKey: LogicalKeyboardKey#00104(keyId: "0x100000104", keyLabel: "Caps Lock", debugName: "Caps Lock"), physicalKey: PhysicalKeyboardKey#70039(usbHidUsage: "0x00070039", debugName: "Caps Lock"), repeat: false) and its data: RawKeyEventDataAndroid#d1f09(flags: 8, codePoint: 0, plainCodePoint: 0, keyCode: 115, scanCode: 58, metaState: 0) 'package:flutter/src/services/raw_keyboard.dart': package:flutter/…/services/raw_keyboard.dart:1 Failed assertion: line 688 pos 7: 'event is! RawKeyDownEvent || _keysPressed.isNotEmpty'

Any idea what the problem could be? Is it a problem of the library or off the scanner? Im working on Flutter version 3.0.3

This seems to be an issue with Flutter itself. I've seen some of these myself when running linux applications in debug-mode, even without this library.

This has gone stale. Closing it.
