How to convert Unix timestamp to Datetime in Dart

🎈 🎈 🎈


    void main() {
        int unixTimestamp = 1192609211;  // Example Unix timestamp
        DateTime dateTime = DateTime.fromMillisecondsSinceEpoch(unixTimestamp * 1000, isUtc: true);
        
        print('Converted Date: $dateTime');
        }

Output:

Converted Date: 2007-10-17 08:20:11

Example only. There may be multiple ways to perform this operation.

Code Explanation

To convert the Unix timestamp '1192609211' (representing 2007-10-17 08:20:11 UTC) to date in Dart it is passed to DateTime.fromMillisecondsSinceEpoch() after multiplying it by 1000 to convert it from seconds to milliseconds.
The isUtc: true flag indicates that the time is in UTC. The function converts the timestamp into a DateTime object, which is then printed in a human-readable format.
