decodeObject<T extends Coding> method
Returns the instance of T
associated with key
.
inflate
must create an empty instance of T
. The value associated with key
must be a KeyedArchive (a Map). The values of the associated object are read into
the empty instance of T
.
Implementation
T? decodeObject<T extends Coding>(String? key, T inflate()) {
final val = _getValue(key);
if (val == null) {
return null;
}
if (val is! KeyedArchive) {
throw new ArgumentError(
"Cannot decode key '$key' into '$T', because the value is not a Map. Actual value: '$val'.");
}
return _decodedObject(val, inflate);
}
