sl_flutter_blue #

Introduction #

sl_flutter_blue is a Bluetooth Low Energy plugin for Flutter.
It is a maintained fork of the original flutter_blue, adapted and updated by Giuliano Jordao / Scrumlab for modern Flutter and Dart versions.

This plugin provides a cross platform Bluetooth LE API for Android and iOS.

Status #

This library is actively used in production apps and the API can evolve until it reaches a stable 1.0.

• Be prepared to handle breaking changes when updating.
• Always test on a real device, emulators usually have limited or no BLE support.

If you have trouble adapting to the latest API or have a specific use case, feel free to open an issue in the GitHub repository.

Cross platform Bluetooth LE #

sl_flutter_blue aims to expose as much functionality as possible from both platforms, Android and iOS.

Using the FlutterBlue singleton you can:

• Scan for nearby BLE devices
• Connect to devices (BluetoothDevice API)
• Discover services (BluetoothService), characteristics (BluetoothCharacteristic) and descriptors (BluetoothDescriptor)
• Read and write values
• Subscribe to notifications and indications

Once you have a BluetoothDevice instance you use it to interact with its services, characteristics and descriptors.
