I do AngularDart development on Windows 10. I'm getting strange behavior with webdev recently. I have to run webdev like this:
C:\Users\galankus>C:\tools\dart-sdk\bin\pub.bat global run webdev
A tool to develop Dart web projects.
Usage: webdev <command> [arguments]
Global options:
-h, --help Print this usage information.
Available commands:
build Run builders to build a package.
help Display help information for webdev.
serve Run a local web development server and a file system watcher that re-builds on changes.
Run "webdev help <command>" for more information about a command.
If I try to run it directly, the below is what I get. Any ideas on how I can debug/fix this?

I just generated 10000 files in the Flutter app project in VSC:
{placeholder0, placeholder1 ..., placeholder10000}
Each file contains simple widget returning next Placeholder, like Placeholder0 widget returns Placeholder1 widget and so on.. where Placeholder10000 returns just Text('test').
(What I also noticed VSC behaviour is getting strange once so much files is placed inside the project, like Dart Analyzer is super lagging. I could not fint any info about number of files limitations within the project). Actually is it possible to run the project with such of big number of files inside it?
Once I put Placeholder0 widget in the body of my HomePage try to run the app on simulator (iOS Simulator) i got following StackOverFlow error:
The relevant error-causing widget was
Placeholder453
lib/placeholders/placeholder452.dart:9
When the exception was thrown, this was the stack

I follow this guide. After unzip flutter I run flutter doctor and take an error

I just updated my dart application and did a pub cache repair afterwards.
The application does not run and debug throws the following exception
Uncaught Unhandled exception:

The application was running quite well before.
Possible bug?
Thanks
