+`var onCriticalErrorHandler: ((`[`Throwable`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-throwable/index.html)`?) -> `[`Boolean`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)?`

+A callback to invoke whenever an uncaught error is encountered. By definition, the return
+value of the function is ignored because this error is unrecoverable. The only reason the
+function has a return value is so that all error handlers work with the same signature which
+allows one function to handle all errors in simple apps. This callback is not called on the
+main thread so any UI work would need to switch context to the main thread.
