VendorDictionary<V>.fromMap constructor
Emulate VendorDictionary behaviours from Map by simply creating VendorDictionary.instant and yield all Map.entries contents.
Implementation
factory VendorDictionary.fromMap(Map<String, V> map) =>
VendorDictionary.instant(() async* {
for (var DictionaryEntry(key: k, value: v) in map.entries) {
yield (k, v);
}
});
