I can work on this

This might be a regression added by PR https://github.com/CCExtractor/taskwarrior-flutter/pull/448 Because it works fine with https://github.com/CCExtractor/taskwarrior-flutter/pull/417

@SGI-CAPP-AT2 I reverted the changes made by PR #448 and the issue still persists. So I don't think it is due to that. I am working on the issue and have fixed it partially.

@SGI-CAPP-AT2 If you want you can try fixing it. I tried but there seems to be some issue I can't understand. I fixed it partially fixed it by adding unknownRoute to SplashScreen that fixed the widget click when the app is closed but when the app is in background and the widget is clicked it gets stuck in SplashScreen with that fix as the arguments passed to DetailRoute turns out to be null although it is not null when we pass it. If you have any idea why is it happening please let me know I can try fixing it or you can go ahead and fix it.

Yes, I'll try and will let you know about problem if fixed
