It runs fine on the Android / iPhone emulators.
I tried the following but all in vain:
flutter 2.0.6 (stable)
flutter 2.5.3 (stable)
flutter doctor shows nothing wrong
flutter clean, flutter pub cache repair, flutter pub get
Restart VSCode
Actually, the issue was coming from the dependency styled_text.
I copied only the files that we needed from the repo and that solved the issue.

Because state_login depends on firebase_messaging ^20.0.1 which doesn't match any versions, version solving failed.

I recently changed some things in my project ( not in the pubspec.yaml file until then ) and since then, everytime I open the project, a message pops up in the bottom right corner saying "Flutter Setup: Running pub upgrade ".
I tried:
Installing dart and flutter extentions new.
Reinstalling VS-Code
Delete the Versions next to the dependencies and re-adding the newest version of each package.
To reproduce:
clone "https://github.com/IfClause/info_app_project.git" and open in VS-Code.
Thanks!

And so on.
Sometimes there are some mysterious issues with Flutter's cache.
If it is the case, flutter clean && flutter doctor should do it for you.
Also, it can happen to people with poor connections or behind firewalls.
