The Linux platform channels sample makes a call to the libupower function up_client_get_devices, which was deprecated in libupower 0.99.8 in favour of up_client_get_devices2.

In order to build both for users on older versions of libupower, such as 0.99.7, which ships with Ubuntu 18.04 (Bionic), as well as users on newer versions where up_client_get_devices is deprecated, this adds a preprocessor check and selects the function available on the host system on which the build takes place.

The Flutter devicelab prod bots have been migrated to Ubuntu 20.04 LTS (Focal) which includes 0.99.11, but the trybots are still in the process of being migrated. This allows the build to work on both, and makes life easier for users running on a variety of Linux distributions.

No tests are added or modified since up_client_get_devices and up_client_get_devices2 have the same semantics.

Note: the UP_CHECK_VERSION macro has been around since 2010 (13 years ago), when DKP was forked into libupower. https://gitlab.freedesktop.org/upower/upower/-/commit/27fada20be7feba6783abc5b6cad91ee274ad3df

test-exempt: needed to build on different versions

I guess if we really wanted we could explicitly try to build against different versions but that seems like a path that leads to insanity rather quickly.

I guess if we really wanted we could explicitly try to build against different versions but that seems like a path that leads to insanity rather quickly.

Honestly, if there's a way to run on 18.04, 20.04, and 22.04 (and enough hardware) I would love to enable that. I'll ping the infra team to see whether that's reasonable given our current infra and capacity.
