debugging - Flutter doesn't render Windows app in debug mode - Stack Overflow

I've been trying to debug my Windows application, but it doesn't render properly. Meanwhile, the release version of the app works just fine. This is the debug view: Windows app with render problems

Coincidentally, this happened right after I added a main() method to a file other than main.dart.

I tried updating all dependencies, both Flutter and VS Build Tools, plus I ran flutter clean in the terminal, to no avail. Creating a new Flutter project doesn't cause the issue, though. I'm also using this .gitignore file, so checking out previous commits didn't solve the issue: /.gitignore

Normally, main() is called only once and serves as the entry point, it initializes Flutter and starts the app. Once the app starts, main() is not called again unless explicitly restarted.

main() can be called multiple times in 3 cases

1- In Flutter debug mode(during development), when you do a Hot Restart (NOT IN DESKTOP DEV), the app fully restarts and calls main() again.

2- One can explicitly call main() inside the app, I do not recommend for security..multiple instances of the app running in memory..

3- After a Crash

Solutions:

1- for desktop apps try to restarted manually to recall the main().

2- call runApp() multiple times without restarting main(), but it will replace the widget tree
