system_idle_linux

The Linux implementation of system_idle. Since this package uses FFI, it can be used in any Windows device with or without Flutter. If you are using Flutter, simply import package:system_idle and this package will be included for you.

Usage

First, initialize the plugin:

// Flutter apps:
import "package:system_idle/system_idle.dart";
// Non-Flutter apps:
import "package:system_idle_linux/system_idle_linux.dart";

// Flutter apps:
final plugin = SystemIdle();
// Non-Flutter apps:
final plugin = SystemIdleLinux();

await plugin.init();

Then you can check how long the user has been idle for:

final duration = await plugin.getIdleDuration();
print("The user has been idle for ${duration.inSeconds} seconds");

Or request a stream for one-off events:

plugin.onIdleChanged(idleDuration: Duration(seconds: 5)).listen(_onIdleChanged);

void _onIdleChanged(bool isIdle) => isIdle
  ? print("The user has been idle for at least 5 seconds")
  : print("The user is no longer idle!");

When you are done, be sure to call dispose, after which any streams obtained by onIdleChanged will stop emitting events.

Compiling

Flutter apps will automatically compile the native code for this plugin.

You'll need to have libxcb installed, including the screensaver extensions.

To build, simply install libxcb and run the Makefile:

sudo apt install libxcb1-dev libxcb-screensaver0-dev
make -C src

The dynamic libraries will be in dist/. Make sure these files are on your PATH or your current directory when you run your code.
