# tryParse 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;
      }
    }
