Flutter Unhandled Exception: FormatException: Invalid date format

Question

I am trying to format my date and time.

My code

    String dateStart = data[i]['notification_date'];
    DateTime input = DateTime.parse(dateStart);
    String datee = DateFormat('hh:mm a').format(input);

its showing error Unhandled Exception: FormatException: Invalid date format

right now its look like this 22-04-2021 05:57:58 PM

what is the 'a' in the format that doesn't seem correct – ahmetakil Apr 22 '21 at 16:20 — ahmetakil, Apr 22 '21 at 16:20

You have an issue in following line:

DateTime input = DateTime.parse(dateStart);

Thing is that default parse method does not support '22-04-2021 05:57:58 PM' format, as it is not standard. You should specify its format to parse like this:

  String dateStart = '22-04-2021 05:57:58 PM';
  DateFormat inputFormat = DateFormat('dd-MM-yyyy hh:mm:ss a');
  DateTime input = inputFormat.parse(dateStart);
  String datee = DateFormat('hh:mm a').format(input);
