tryParse static method Null safety

DateTime? tryParse(
  1. String formattedString
)

Constructs a new DateTime instance based on formattedString.

Works like parse except that this function returns null where parse would throw a FormatException.

Implementation

static DateTime? tryParse(String formattedString) {
  // TODO: Optimize to avoid throwing.
  try {
    return parse(formattedString);
  } on FormatException {
    return null;
  }
}
