suspendCancellableCoroutine : suspendCancellableCoroutine 的挂起函数内在协程取消后将会抛出一个 CancellationException , 协程默认不处理这个异常,如果对其进行 try catch, 将会捕获到 CancellationException异常 , it.resume(logoUrl) 执行后,将无法唤起恢复挂起函数继续运行 . suspendCoro...

编译器可以验证我们尝试访问的任何属性或方法或特定类实例是否真的存在。这应该是熟悉的 Java,它也是静态类型的,但与 Java 不同,Kotlin 的类型系统更加严格(安全)。我们必须明确告诉编译器给定的变量是否可以存储空值。这允许在编译时使程序失败,而不是在运行时抛出NullPointerException:...
The iOS application is produced from an Xcode project. It's stored in a separate directory within the root project. Xcode uses its own build system; thus, the iOS application project isn't connected with other parts of the Multiplatform Mobile project via Gradle. Instead, it uses the shared...
