Koin（依赖注入）-使用

• 懒加载 与 立即加载 // Lazy Inject ViewModel，注入依赖 val mainViewModel: MainViewModel by viewModel() // Inject ViewModel, not lazy // val mainViewModel: MainViewModel = getViewModel() //可能会报错：Your activity is not yet attached to the Application instance. You can't request ViewModel before onCreate call

  // Lazy Inject Class val person: Person by inject() // Inject Class, not lazy // val person: Person = get()

• startKoin

• module

• single

• factory

• viewmodel

• fragment

• by inject()/get()，前者在Android的运行时组件（AFSC）有效

• by viemwodel()/getViewModel()

• named()//限定标示符，string和type

• bind类似于类型扩展，接口实现，通过get获取，泛型时候，koin.bind(T,instance)来获取，另有getAll（）
