AvoidDirectMethodChannel class

禁止业务代码直接实例化 MethodChannel 或 EventChannel。

原因：

  • 没有统一的错误语义（PlatformException → AppException 转换缺失）；
  • 没有 channel 名称注册中心，容易 typo；
  • 测试时无法按 method 粒度 mock，只能全局 setMockMethodCallHandler；
  • VM 直接触达原生层，违反分层——应该经 DataSource → Repository。

要求改用 ChannelClient（flutter_spine/network），或在此之上做一层 业务 ApiClient 封装；ViewModel 只调 Repository。

豁免

  • flutter_spine 的 ChannelClient 实现本身：package/flutter_spine/lib/src/network/**
  • 测试 / fixture / example 路径
  • 应用启动代码 /lib/main.dart / lib/bootstrap.dart
