Can't open the file picker to set download location

[gursuj]

I'm using the aur package on Arch Linux. When trying to set the download location, it doesn't open the file picker and instead prints this to the terminal:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Exception: Couldn't find the executable zenity in the path.
