## What it is
FlutterBlue is a Bluetooth LE plugin for Flutter that enables scanning, connecting, and interacting with nearby BLE devices from Dart code. It provides a unified cross-platform API over iOS and Android for discovering services, characteristics, and descriptors and reading/writing their values.

## Use cases
- scan for nearby bluetooth devices in a flutter app
- connect to a BLE heart rate monitor from mobile app
- read and write characteristics on a bluetooth device
- subscribe to characteristic notifications over BLE
- discover GATT services on a connected peripheral
- build a cross-platform IoT companion app with BLE

## When to choose
- you are building a Flutter app that needs Bluetooth Low Energy communication on iOS and Android
- you want a single Dart API for BLE scanning, connecting, and GATT operations
- you need to interact with BLE peripherals like sensors or wearables from a mobile app

## When to avoid
- you need Bluetooth Classic (not BLE) profiles like audio or SPP
- you are not using Flutter for your mobile app
- you need a fully stable API with no breaking changes, since the project is pre-1.0
- you need desktop or web Bluetooth support

- artifact type: plugin
