I am new to Linux and learning. Recently I installed "Eclipse" IDE for Java from the Software Store (Flatpak version). I need an add-on/software "PlantUML" which requires "Graphviz".
Now the problem is that Graphviz is not available in FlatPak so I installed it via "sudo apt-get install ...." So Eclipse and PlantUML can't find it.
TLDR: I am running a software installed through flatpak and it requires a software which is not available in flatpak to I installed it bia APT. As flatpak runs on sandbox it can not find the software. Which should I do in this case?
Also how to use -option in termial while lunching flatpak apps?
