How does Dart VM Garbage Collection Work?

[Haha Guy]

Before diving into the implementation details, Im wondering how GC works with Dart_Handle to ensure safe memory management.

Dart_Handles point to regular Dart objects and during GC all these handles become part of the root set used

to determine if an object is still in use.

There are two kinds of handles the Scoped local handles which are live only within a scope created using

Dart_EnterScope and exited with Dart_ExitScope. The other kind of handles are the persistent handles

created using Dart_NewPersistentHandle and these handles are live across scopes until they are deleted

using Dart_DeletePersistentHandle

Thanks for the reply bro. You mentioned that "all these handles become part of the root set ", how is the rest of the root set decided for each isolate?
