flutter_gpiod is a Dart package that enables low-level GPIO (General Purpose Input/Output) access on Linux and Android devices via the GPIO character device interface. It requires root access on Android and is designed for IoT applications needing direct hardware control. The package supports edge-triggered signal listening, configuration of active high/low states, open-drain/open-source modes, and optional bias settings where supported by the underlying platform. It's ideal for developers building embedded or hardware-integrated Flutter apps with precise GPIO control.
Use cases
- Hardware control in IoT devices
- Real-time sensor input monitoring
