MarsSeed [1] filed a deletion request for python2-flowui [2]: Unneeded package from 2015 for a Python2 module not developed since 2014. [a]
Its AUR consumer, python2-voidwalker{,-git} is also discontinued since
2014 and broken due to its dependency, gdb no longer supporting
Python2 modules.
Safe to delete this package.
