Flutter - How to convert time stamp string from 24 hr format to 12 hr format in dart?

In Dart, you can convert a timestamp string from a 24-hour format to a 12-hour format using the DateFormat class from the intl package. First, you'll need to add the intl package to your pubspec.yaml file:

dependencies: flutter: sdk: flutter intl: ^0.17.0

Then, you can use the DateFormat class to parse the timestamp string and format it in the desired format. Here's how you can do it:

import 'package:intl/intl.dart'; String convertTimeTo12HourFormat(String timestampString) { // Parse the timestamp string DateTime dateTime = DateTime.parse(timestampString); // Format the datetime in 12-hour format String formattedTime = DateFormat('hh:mm a').format(dateTime); return formattedTime; } void main() { // Example usage String timestampString = '2022-05-05 13:30:00'; // Assuming timestamp is in this format String formattedTime = convertTimeTo12HourFormat(timestampString); print(formattedTime); // Output: 01:30 PM }

In this example, convertTimeTo12HourFormat function takes a timestamp string in a format such as '2022-05-05 13:30:00', parses it into a DateTime object, and then formats it using the DateFormat class with the pattern 'hh:mm a'. The pattern 'hh:mm a' represents hours in 12-hour format, minutes, and 'AM' or 'PM' indicator. Finally, the formatted time is returned.
