externalUsage property

int? externalUsage
getter/setter pair

The amount of non-Dart memory that is retained by Dart objects. For example, memory associated with Dart objects through APIs such as Dart_NewFinalizableHandle, Dart_NewWeakPersistentHandle and Dart_NewExternalTypedData. This usage is only as accurate as the values supplied to these APIs from the VM embedder. This external memory applies GC pressure, but is separate from heapUsage and heapCapacity.
