I have now wasted a couple of hours on getting the app at least to build before I can even start making changes. But it won't build and I can't figure out why. Additional problem is, that this is not a "old-school" Android project in Java (or Kotlin). It is a Flutter project and it uses Dart as language which I have never used.

Additionally, there is an automatic build server that I maybe could have used to infer what the problem for me is, but even it fails to build the app. I cannot look into the older successful runs since the logs have been deleted since. Clearly something has changed from the build tools used but I cannot guess what (correctly). This is the outcome of the problem when nobody uses fixed versions but rather defined "newest", which now breaks everything and nobody knows with what versions it worked.

So I tried Flutter 3.16.0 and 3.13.9 which are most likely too new since it complains about missing and wrong stuff. With 3.10.6 tries to build but it somehow stops without any reason given and I cannot find out how to get it to tell me what the F the problem is.

Sorry for my rambling but I hate this shit and maybe this helps someone.
