support the filepicker portal

[secretmango]

hey, very smooth app!

For the Flatpak to work well, and on Linux in general it looks nicer, it would be a huge benefit to support the native xdg-desktop portal.

This means the Flatpak would not need any static filesystem permissions.

Hi there, thanks for the feedback.
Unfortunately, I don't think Scrivano can rely on file choosers via Flatpak. The reason is that autosaving files (which is a core feature of Scrivano) requires reading/writing files without user interaction.

Hi, interesting reasoning.

I see how the flatpak permissions are pretty annoying, but autosaving should not be the problem.

When opening a file via the portal it is symlinked to the apps container, so autosaving works. A "user interaction" really only is when users would open the portal program. An interaction within the Flatpak is not a "user interaction", as the portal is the one with "the power".

The only workflow that breaks because of this opening previously opened documents from within the app. So a workflow

1. open filemanager
2. open document, opens scrivano
3. scrivano gets access to the file and can save as much as it wants.

works fine.

Example: KDE Okular Flatpak works completely without filesystem access. Both opening from the filemanager and via the portal give it the ability to save changes with "Ctrl + S" i.e. without opening a portal i.e. without "user interaction".

Only if you do something like KeepassXC, displaying and opening the previously edited document(s) when launching the app, then it is problematic.

I think this could be circumvented by using "xdg-open" but I am not sure.

Hmm interesting, I didn't know about this so I'll look into this.

Yes, this is another use case I'm not sure could be supported with Flatpak (Scrivano does allow you to this), but I'll investigate.

However, more importantly, in a future update I plan to add an in-app side bar (something I'm already working on) which would allow the user to navigate their existing documents (essentially providing a view of a given folder on their system). This I believe would require file system permissions and I would not want to avoid bifurcating the experience for Flatpak and non-Flatpak users.
