asStringOrNull method

String? asStringOrNull()

Returns the picked value as String or returns null when the picked value isn't available

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? asStringOrNull() {
  if (value == null) return null;
  try {
    return _parse();
  } catch (_) {
    return null;
  }
}
