Class DebugMetadata

java.lang.Object

com.facebook.litho.DebugMetadata

public class DebugMetadata
extends java.lang.Object

DebugMetadata is a special class that allows custom key-value pairs to be appended to LithoMetadataExceptionWrapper when it wraps an exception. To use it, create a DebugMetadata tree prop via @OnCreateTreeProp and add custom metadata you want to appear in crashes. Any crash coming from that subtree will contain this metadata in the LithoMetadataExceptionWrapper. Make sure to pass in the existing DebugMetadata tree prop if there is one.

Example:
