asStringOrThrow method
Returns the picked value as String representation; only throws a
PickException when the value is null
or isAbsent.
Parses the picked value as String. If the value is not already a String its Object.toString() will be called. This means that this method works for int, double and any other Object.
Implementation
String asStringOrThrow() {
withContext(
requiredPickErrorHintKey,
'Use asStringOrNull() when the value may be null/absent at some point (String?).',
);
return _parse();
}
