Kotlin 'unsafe call on nullable receiver' compile error after null check
Question
This is the screenshot of the error:
I'm using Intellij v14.0.1 + Kotlin plugin v0.9.206. My understanding is that after the null check, the compiler shouldn't show me the error. Am I wrong?

target属性是var ，这就是为什么它不保证在第三行上这个属性不能为null（例如另一个线程可以将它设置为null ）

AFAIK, a property can be a method call and then nothing can be guaranteed. Use a local val .
