grants property
Who holds what, for an entitlements view.
hasEntitlement answers one pair at a time, so a customer who lost
access and one who never had it are indistinguishable without this.
Implementation
Map<String, Set<String>> get grants => Map<String, Set<String>>.unmodifiable(
<String, Set<String>>{
for (final entry in _grants.entries)
entry.key: Set<String>.unmodifiable(entry.value),
},
);
