startCoroutine首先是调用了createCoroutineUnintercepted函数,而createCoroutineUnintercepted是expect的,它是一种声明。因为Kotlin是跨平台的,所以部分逻辑与平台相关,这个createCoroutineUnintercepted就是这种。它没有函数体,我们只关心JVM平台,所以需要到JVM平台上找该函数的实现。在Kotlin源码地图文章中,我们提到协程源码,分...
在Kotlin 中使用 by lazy 时,如果遇到 “Unable to create instance of interface kotlin.lazy: Registering an instance creator” 这类错误,通常意味着你试图在不应该使用 by lazy 的地方使用了它,或者在使用方式上有误。不过,根据你提供的信息,这个问题似乎与 kotlin.lazy 无关,而是与 kotlinx.coroutines.flow...
