Linux: Use tray_manager instead of system_tray; remove system_tray

[ix5]

Using tray_manager for Linux as well allows ditching of the unreliable and seemingly less-than-well maintained flutter library system_tray and unifies desktop tray handling across platforms.

At the same time, use upstream tray_manager instead of a forked repo (which was stuck on 0.2 and did not contain e.g. leanflutter/tray_manager#38 ). This additionally enables building on Linux again since Tienisto's forked repo used to disable the Linux plugin: Tienisto/tray_manager@b37f5e0. This also works around issues with newer libayatana-appindicator versions: leanflutter/tray_manager#38

Caveats discussed previously still apply: #404

Mainly:

• Flutter versions installed using snap having incompatible GLib: Failure to build on Ubuntu - "undefined reference to `g_time_zone_new_identifier'" leanflutter/tray_manager#30 and On Linux Mint 21 and Ubuntu 22.04 unable to build using libayatana library. undefined reference to `g_time_zone_new_identifier' leanflutter/tray_manager#28.
  Note that the incompatibility should have existed with both system_tray as well as tray_manager, the latter being a slightly more maintained fork (?) but utilizing very similar build macros
• Reliance on libayatana-* packages

As for @TheGB0077 saying:

(I tried to make the tray manager work for Linux but it didn't work still)

I'm not quite sure what the issue was, but it seems to work okay now. The only thing to keep note of for me was to guard the call to setToolTip() since it would throw a MissingPluginException on Linux, but this was noted in the API docs of tray_manager.

For reference, potentially relevant prior discussions/commits:

• 53b1899
• Segfault when launching the 1.9.0 appimage #409
• Feature request: Creating a menu bar indicator for easier access on Desktops. #651

Issues?

I have only tested this on an up-to-date Arch Linux system and cannot speak to the viability of tray_manager for other (older) distros.

It seems that the AppImage and Flatpak distributors as well as Debian-based systems might not be fully compatible with anything recent, but I cannot see how re-enabling tray_manager on Linux would surface any additional errors that weren't previously being thrown by system_tray.

My setup:

libappindicator-gtk3 12.10.0.r298-3
libayatana-appindicator 0.5.93-1
libayatana-indicator 0.9.4-1
libcanberra 1:0.30+r2+gc0620e4-3

With flutter installed through fvm:

$ fvm flutter --version

@Nixuge I see your efforts at packaging for the AUR. With this PR (for me locally) I can successfully use LocalSend with a tray icon again.

Note however that this is using the generated artifacts (flutter build linux --release) for packaging using a PKGBUILD and not extracting anything from the debian tarballs.

See #40

I'm not quite sure what to do about segfaulting AppImages (see #409) but interested in what others might report.

[Tienisto]

Thanks for your effort! I will test this ASAP

[ix5]

Splendid, thank you @Tienisto! You've created and maintained a great app, I'm happy to contribute.

Pushed with a fix for the CI complaining about unused imports (it was dart:io that I missed because I didn't realize exit(0) belonged to that lib... sorry, first time using flutter/dart)

[Tienisto]

LGTM!

[Nixuge]

Finally here, will try and switch the -bin aur package to use the deb/targz see if it works

[Nixuge]

Note however that this is using the generated artifacts

Those seem to work just fine anyways (see the -git AUR package) unlike the .deb & .tar.gz from the releases tab for some reason (no idea how you're making those @Tienisto?)

Anyways if you got rid of that dependency it's probably fixed anyways, thanks for the epic PR.

Got a PKGBUILD for deb support ready for when this gets into a release build

[Tienisto]

The release binaries are all built on the Github Pipeline:

Aight thanks, did a test build and it seems to work perfectly now with the deb
