LateInitializationError on Windows. After updating to Flutter 3.10 and Dart 3.0.0 #91

• Flutter version 3.10.0 on channel stable at D:\Flutter
• Framework revision 84a1e904f4 (5 days ago), 2023-05-09 07:41:44 -0700
• Engine revision d44b5a94c9
• Dart version 3.0.0
• DevTools version 2.23.1

I'm using flutter stable channel, recently updated to Flutter 3.10 and Dart 3.0.0. Now the QuickUsb library does not work. After calling var init = await QuickUsb.init(); a LateError occurs (LateInitializationError: field '_instance@326265524' was not initialized).

This happens on the Windows 11 platform, everything is fine on Android. Not tested on other platforms. I tried to clear the cache in .dart_tool, it did not help.

I tried using a later version of quick_usb 0.3.1. And no problems, everything works.

I can confirm that I see the same symptoms for 0.4.0 , but on macOS (Dart 3.0.1). And that forcing the version to 0.3.1 indeed allows avoiding the error.

Any solution for this problem? Although it works for 0.3.1, I can't open device on linux.

Even getting a device list causes my entire app to hang, not sure why. This is 0.3.1 (hangs even with proper future handling) 0.4.0 is a non-starter - same issue.

Any alternatives guys ?

TheAnimatrix commented 6 months ago

Alright i fixed both the error and my laggy issue

1 -> Check your platform and run QuickUsbWindows.registerWith() before init() if you platform is windows. You have functions for each platform. This should solve the initialization error 2 -> if you find the futures are blocking despite waiting for them asynchronously thats natural, you are running all the USB calls on the main thread with high priority. Throw them in an isolate and you should be fine. You have to register, init and exit while in the isolate, dont forget!
