Errors when doing Linux build

[LuFlo]

I reopened a project which I was working on before and which I definitely built before. First I had the same issues as described on this stackoverflow: https://stackoverflow.com/questions/67396100/flutter-linux-build-error-when-executing-flutter-run-d-linux

I installed the packages which were suggested:

sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev
flutter clean
flutter run -d linux

After installing the packages, I got some weird c++ compilation errors. I also tried updating to the edge-channel, I removed the build folder, ran flutter clean and rebuilt multiple times.

Exception: Build process failed

Btw, I'm on PopOS 22.04. Anyone some ideas? I will also try to install flutter manually and post here if there are the same issues.

The manual flutter install works fine, I just had to make sure to delete do a clean rebuild: flutter/flutter#66477
