Overview
Flutter Blue Plugin is a cross-platform Flutter package enabling communication with Bluetooth Low Energy (BLE) devices on Android, iOS, macOS, and Windows. It provides a unified API for discovering, connecting to, and exchanging data with BLE peripherals. The plugin supports scanning for devices, reading and writing characteristics, subscribing to notifications, and managing connections. Built on top of native BLE stacks, it ensures reliable performance across platforms. Ideal for developers creating apps that interact with wearables, sensors, beacons, and other BLE-enabled hardware.
