android - Koin 范围和接口(interface)

Question

我正在使用 Koin我项目中的 di 库。 lib 版本为 1.0.0-RC-1。

我的模块:

val appModule = module {
    scope("UserScope") { UserToaster(androidContext()) as Toaster }
    scope("AnonScope") { AnonToaster(androidContext()) as Toaster }
}

我在我的 Application 类中开始 koin 并创建了 scope:

override fun onCreate() {
    super.onCreate()

    startKoin(this, listOf(appModule))
    getKoin().getOrCreateScope("AnonScope")
}

接下来，我尝试将 Toaster 的实现从当前作用域注入(inject) Activity 中的变量。这里的代码:

private val toaster: Toaster by inject(scope = "AnonScope")

之后我得到一个错误:

Caused by: org.koin.error.DependencyResolutionException: Multiple definitions found for type 'interface com.example.nkirilov.playground.Toaster (Kotlin reflection is not available)' - Koin can't choose between :
    Scope [name='UserScope',class='com.example.nkirilov.playground.Toaster']
    Scope [name='AnonScope',class='com.example.nkirilov.playground.Toaster']
    Check your modules definition, use inner modules visibility or definition names.

我不明白为什么这不起作用(如果使用具有不同名称的 single - 它会起作用)。那是 koin 错误吗？如何避免这个错误？

我是这样实现的

模块:

val navigationModule = module {
    scope(DI.APP_SCOPE) { ClassA().create }
    scope(DI.APP_SCOPE) { get(scopeId = DI.APP_SCOPE).classB }
    scope(DI.APP_SCOPE) { get(scopeId = DI.APP_SCOPE).classC }
}

val authModule = module {
    scope(DI.AUTH_SCOPE) { ClassA.create(ChildClassB(get(scopeId = DI.APP_SCOPE))) }
    scope(DI.AUTH_SCOPE) { get(scopeId = DI.AUTH_SCOPE).classB }
    scope(DI.AUTH_SCOPE) { get(scopeId = DI.AUTH_SCOPE).classC }
}

主要 Activity :

private val classC: ClassC by inject(scope = getKoin().getOrCreateScope(APP_SCOPE))

AuthActivity:

private val classC: ClassC by inject(scope = getKoin().getOrCreateScope(DI.AUTH_SCOPE))
