Overview
The upower package provides a Dart client for connecting to UPower, a Linux system service responsible for power management. It enables Flutter applications running on Linux to access battery status, power supply information, and device charging states. This integration allows developers to build desktop apps that monitor and respond to power-related events in real time. The package is maintained by Canonical and is specifically designed for Linux environments, offering a lightweight way to interact with system-level power data through the D-Bus interface.
Use cases
