FluentApp error while developing in debug

[maik-kluwe]

From time to time i got the following error:

It seems that an"empty" constructor is missing.
A hot-reload resolves the problem but i think it should be possible to resolve this error entirely to not hot-reload each time.

Can you please show the whole logs?

Next time i get the error i will post the complete error.
But in my understanding the shown error is complete. It occures sometimes if the hot-reload triggers. I do not change anything in the top of the widgets tree.

I never got this error. I'd like to know from what line it comes.

This is the entire log: (I replaced the project name with PROJECT). Below the error message i posted the main.dart

Widget creation tracking is currently disabled. Enabling it enables improved error messages. It can be enabled by passing --track-widget-creation to flutter run or flutter test.
When the exception was thrown, this was the stack

class MyApp extends StatelessWidget {
@OverRide
Widget build(BuildContext context) {
return FluentApp(
title: "PROJECT",
debugShowCheckedModeBanner: false,
initialRoute: '/',
routes: {
'/': (_) => MainPage(),
},
);
}
}

The MainPage is pretty much the same from the given example project with one "DatabaseEdit" and one SettingsPage.

I hope this will help you :)

Hey! According to the error. it's not an issue with the package, since it comes from main.dart#1

I searched in my whole fluent_ui workspace and the only place FluentApp. is mentioned is at FluentApp.router:

Then it must be a problem in my main.dart file. I will have a look at it.
Thanks for your help :)
