adapterState property

Stream<BluetoothAdapterState> get adapterState

监听蓝牙适配器状态变化。

无参数。Android/iOS/macOS 会推送系统状态变化；Linux 监听 BlueZ Adapter PropertiesChanged 并在订阅时先发送当前状态；Web 先发送当前 availability 映射状态， 并在浏览器 availabilitychanged 时更新。建议用它驱动 UI，而不是频繁轮询 getAdapterState。

Implementation

Stream<BluetoothAdapterState> get adapterState {
  throw UnimplementedError('adapterState has not been implemented.');
}
