parse method
Given user input, attempt to parse the inputString
into the anticipated
format, treating it as being in the local timezone.
If inputString
does not match our format, throws a FormatException.
This will accept dates whose values are not strictly valid, or strings
with additional characters (including whitespace) after a valid date. For
stricter parsing, use parseStrict.
Implementation
DateTime parse(String inputString, [bool utc = false]) =>
_parse(inputString, utc: utc, strict: false);
