Overview
Flutter Blue is a Flutter plugin enabling communication with Bluetooth Low Energy (BLE) devices on Android, iOS, and macOS. It provides a straightforward API to scan for BLE peripherals, connect to them, read and write characteristics, and receive notifications. Designed for developers building apps that interact with wearable devices, sensors, or IoT hardware, it abstracts platform-specific BLE implementations into a unified interface. The package supports background operations and real-time data streaming, making it ideal for health, fitness, and smart home applications. Maintained by Paul DeMarco, it integrates seamlessly with Flutter’s reactive framework.
