stdlibModuleNames property
Known stdlib modules and their registration functions.
Maps dart:xxx path names to their registration callbacks.
null means the module is handled by Stdlib.register at init time
(core, async) and requires no additional registration.
The dart: libraries this loader knows about, including the two that
arrive pre-registered.
Exposed read-only so a guard can drive off the production list rather than a copy of it. SCC76 needs to register every stdlib module into one environment to check for duplicate bridge names, and a hardcoded copy of this list in a test would decay silently — the same failure the guard itself exists to prevent, one level up.
Implementation
static Iterable<String> get stdlibModuleNames => _stdlibRegistrars.keys;
