MethodChannelBluetoothConnect class
蓝牙插件的 MethodChannel / EventChannel 默认实现。
作用:把 Dart 侧 API 通过 Channel 转发到 Android/iOS 原生代码。
调用步骤(内部通信):
- MethodChannel
bluetooth_connect:同步类请求(检测、扫描、连接) - EventChannel
bluetooth_connect/scan_results:推送扫描到的设备列表 - EventChannel
bluetooth_connect/connection_state:推送连接状态变化
