How to convert a string to DateTime and DateTime to ISO8601 in Dart

Dart : Converting a string to DateTime and DateTime to ISO8601 string :

In dart, we can easily convert a string to a DateTime object. DateTime.parse() method takes one correctly formatted string as input and convert it to a DateTime object. Similarly, we can convert a DateTime object to a ISO8601 string using toIso8601String() method. The output is yyyy-MM-ddTHH:mm:ss.mmmuuuZ for UTC time and yyyy-MM-ddTHH:mm:ss.mmmuuu for non-UTC time.

yyyy - Year , from -9999 to 9999
MM - month , from 01 to 12
dd - date, from 01 to 31
HH - hour in 24 hour format, from 00 to 23
mm - minute in range 00 to 59
ss - seconds in range 00 to 59
mmm - milliseconds in the range 000 to 999
uuu - microseconds in the range 001 to 999

We can again parse this string back to a DateTime object using parse() method.

main(List args) {
  DateTime myDatetime = DateTime.parse("2018-07-10 12:04:35");

Output :
