parseDate static method

DateTime? parseDate(String? value)

Implementation

static DateTime? parseDate(String? value) {
  //expected 05.01.2021 01:31:04
  //why should we use own parser instead of import external library ?
  //because we are library and we:
  //1. should be as tiny as possible
  //2. our clients/developers may use different libraries.
