通常 Android App 要上架
release 會作 Proguard/R8
可是在 Google Play console 看當機報告
看到的會是混淆結果
其實可以上傳 mappings
方便在 Google Play console 追蹤

既然提到 mappings
多少要了解 Proguard 有哪些產出

ssh-agent bash

Since Kotlin 1.1, you can access a property delegate directly using .getDelegate().

You can write an extension property for a property reference that checks that it has a Lazy delegate that has already been initialized:

/**
 * Returns true if a lazy property reference has been initialized, or if the property is not lazy.
 */
val KProperty0<*>.isLazyInitialized: Boolean
 get() {

	i(...);
	w(...);
	e(...);
	wtf(...);
	println(...);
