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`. The prod bots have been migrated to focal, which ships libupower 0.99.11 in which the old function is deprecated and the new one is available. The try bots have not yet been migrated and remain on bionic, which ships libupower 0.99.7 in which the old function is not deprecated and the new one is not available. This marks the line in question to ignore deprecation warnings. Once all bots have migrated to focal, we'll migrate to the new function. See tracking issue below.

Example of calling platform services from Flutter
This project demonstrates how to connect a Flutter app to platform-specific services.
You can read more about accessing platform and third-party services in Flutter.
iOS
You can use the commands flutter build
and flutter run
from the app's root
directory to build/run the app or you can open ios/Runner.xcworkspace
in Xcode
and build/run the project as usual.
Android
You can use the commands flutter build
and flutter run
from the app's root
directory to build/run the app or to build with Android Studio, open the
android
folder in Android Studio and build the project as usual.
Windows
You can use the commands flutter build
and flutter run
from the app's root
directory to build/run the app or you can build once then open
build\windows\platform_channel.sln
in Visual Studio to build and run.
