In the software I developed with Flutter desktop, I want to listen to USB ports on Windows and Mac OS operating systems and send and receive byte-type data. Is there a method for this?
I tried the QuickUsb package and I get an error as follows.
flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: LateInitializationError: Field '_instance@66265524' has not been initialized. #0 QuickUsbPlatform._instance (package:quick_usb/src/quick_usb_platform_interface.dart) #1 QuickUsbPlatform.instance (package:quick_usb/src/quick_usb_platform_interface.dart:16:43) #2 _platform (package:quick_usb/quick_usb.dart:10:52) #3 QuickUsb.init (package:quick_usb/quick_usb.dart:13:33) #4 PrinterCubit.initialProcess (package:*_desktop/cubit/printer_cubit.dart:14:14) #5 new PrinterCubit (package:*_desktop/cubit/printer_cubit.dart:10:5) #6 MyApp.build.<anonymous closure> (package:*_desktop/main.dart:64:32) #7 _CreateInheritedProviderState.value (package:provider/src/inherited_provider.dart:736:36) #8 _InheritedProviderScopeElement.value (package:provider/src/inherited_provider.dart:590:33) #9 Provider.of (package:provider/src/provider.dart:303:37) #10 ReadContext.read (package:provider/src/provider.dart:649:21) #11 _BlocListenerBaseState.initState (package:flutter_bloc/src/bloc_listener.dart:143:36) #12 StatefulElement._firstBuild (package:flutter/src/widgets/framework.dart:5611:55) #13 ComponentElement.mount (package:flutter/src/widgets/framework.dart:5456:5) #14 SingleChildWidgetElementMixin.mount (package:nested/nested.dart:222:11) #15 Element.inflateWidget (package:flutter/src/widgets/framework.dart:4335:16) #16 Element.updateChild (package:flutter/src/widgets/framework.dart:3846:18) #17 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:5505:16) #18 Element.rebuild (package:flutter/src/widgets/framework.dart:5196:7) #19 ComponentElement._firstBuild (package:flutter/src/widgets/framework.dart:5462:5) #20 ComponentElement.mount (package:flutter/src/widgets/framework.dart:5456:5) #21 Element.inflateWidget (package:flutter/src/widgets/framework.dart:4335:16) #22 Element.updateChild (package:flutter/src/widgets/framework.dart:3846:18) #735 Element.rebuild (package:flutter/src/widgets/framework.dart:5196:7) #736 ComponentElement._firstBuild (package:flutter/src/widgets/framework.dart:5462:5) #737 ComponentElement.mount (package:flutter/src/widgets/framework.dart:5456:5) #738 Element.inflateWidget (package:flutter/src/widgets/framework.dart:4335:16) #739 Element.updateChild (package:flutter/src/widgets/framework.dart:3846:18) #740 _RawViewElement._updateChild (package:flutter/src/widgets/view.dart:291:16) #741 _RawViewElement.mount (package:flutter/src/widgets/view.dart:314:5) #742 Element.inflateWidget (package:flutter/src/widgets/framework.dart:4335:16) #743 Element.updateChild (package:flutter/src/widgets/framework.dart:3846:18) #744 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:5505:16) #745 Element.rebuild (package:flutter/src/widgets/framework.dart:5196:7) #746 ComponentElement._firstBuild (package:flutter/src/widgets/framework.dart:5462:5) #747 ComponentElement.mount (package:flutter/src/widgets/framework.dart:5456:5) #748 Element.inflateWidget (package:flutter/src/widgets/framework.dart:4335:16) #749 Element.updateChild (package:flutter/src/widgets/framework.dart:3846:18) #750 RootElement._rebuild (package:flutter/src/widgets/binding.dart:1354:16) #751 RootElement.mount (package:flutter/src/widgets/binding.dart:1323:5) #752 RootWidget.attach.<anonymous closure> (package:flutter/src/widgets/binding.dart:1276:18) #753 BuildOwner.buildScope (package:flutter/src/widgets/framework.dart:2844:19) #754 RootWidget.attach (package:flutter/src/widgets/binding.dart:1275:13) #755 WidgetsBinding.attachToBuildOwner (package:flutter/src/widgets/binding.dart:1088:27) #756 WidgetsBinding.attachRootWidget (package:flutter/src/widgets/binding.dart:1070:5) #757 WidgetsBinding.scheduleAttachRootWidget.<anonymous closure> (package:flutter/src/widgets/binding.dart:1056:7) #758 Timer._createTimer.<anonymous closure> (dart:async-patch/timer_patch.dart:18:15) #759 _Timer._runTimers (dart:isolate-patch/timer_impl.dart:398:19) #760 _Timer._handleMessage (dart:isolate-patch/timer_impl.dart:429:5) #761 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:184:12)
