A .tar.gz is a source distribution. To install that, pip needs to build it first, and to build it, it needs a build backend, so it goes downloading the build backend (Flit) on PyPI, which is not possible if the machine doesn't have network access. Try the wheel (.whl) file instead. However, Flask has a number of dependencies that you will need too.
