从字符串中获取日期并在 Flutter Dart 中转换为日期 object

Question

I searched a lot, but couldn't find a good solution. Actually, know the Javascript code to do my problem. But I tried different methods in Dart. My issue is I am fetching a time table through an API. And I get the response as

05:30 (PTC)
13:10 (PTC)
17:20 (PTC)

And I need to get this as

5:30 AM
1:10 PM
5:20 PM

The code I tried and worked in Javascript

     function tConvert (time) {
  time = time.toString ().match (/^([01]\d|2[0-3])(:)([0-5]\d)(:[0-5]\d)?$/) || [time];
  if (time.length > 1) { // If time format correct
    time = time.slice (1);  // Remove full string match value
    time[5] = +time[0] < 12 ? ' AM' : ' PM'; // Set AM/PM
    time[0] = +time[0] % 12 || 12; // Adjust hours
  }
  return time.join (''); // return adjusted time or original string
}

//called as
$("#time").html(tConvert(time));

One more issue here his (PTC) is sometime changed to other codes like (BST) (IST) etc. So just replacing (PTC don't work).

Answer 1

I solved the issues after a long search. So I wished to share my code. Thanks to @hiwa Jalal for trying to help.

Steps were taken:

• Removed all strings with RegEx String removeABC = removebrace2.replaceAll(RegExp(r'[a-zA-Z]'), '');
• Removed spaces and brackets with similar regEx.
• Converted my result into DateFormat

 DateTime gotFinalTime = intl.DateFormat('hh:mm').parse(removeABC);
                 String formattedTime = intl.DateFormat.jm().format(gotFinalTime);

                 print(formattedTime);

This worked for me. Thanks

add intl to your project

then use DateFormat.jm().format(yourTime)
