# tray_manager 0.5.3 is a pub.dev dependency fetched live during the build
# (not part of localsend's own tree), so it can't be applied via the usual
# prep-time autopatch mechanism -- the target file doesn't exist until
# `flutter pub get` fetches it. It's applied manually in the build section
# instead; see the comment there. It calls the
# now-deprecated app_indicator_new() unconditionally; Fedora's
# libayatana-appindicator3 headers mark that G_GNUC_DEPRECATED, and the
# plugin's own CMakeLists compiles with -Werror, turning the warning into a
# fatal build error. Verified with a real mock build (fedora-44-aarch64).

%description
LocalSend is an open source cross-platform app that lets you share files
and messages with nearby devices without an internet connection. This
package builds the Flutter-based desktop client (with its Rust protocol
core, built via cargokit) from source for Linux, plus a systemd --user
unit that starts it in the background the same way LocalSend's own
login-autostart does:

    systemctl --user enable --now localsend

# cargokit (the Rust<->Flutter glue used by packages/localsend_isolates)
# hard-requires a `rustup` binary on PATH to check/install toolchains and
# targets, and always compiles through `rustup run <toolchain> cargo ...`
# rather than calling `cargo` on PATH directly. Since rust-toolchain.toml
# pins exactly %{rust_toolchain} -- matching the rust/cargo BuildRequires
# above -- a real rustup would just download a second, redundant copy of
# the same compiler. This shim reports the pinned toolchain/target as
# already installed and delegates `rustup run <toolchain> CMD...` straight
# to Fedora's system CMD, so the actual compilation still goes through the
# real system cargo/rustc.
