By using this :
Text(new DateTime.fromMillisecondsSinceEpoch(values[index]["start_time"]*1000).toString(),
I am getting the type of format attached in the picture, however I was wondering if I could get it in dd/MM/YYYY hh:mm
??
If you use the intl package
final f = new DateFormat('yyyy-MM-dd hh:mm');
Text(f.format(new DateTime.fromMillisecondsSinceEpoch(values[index]["start_time"]*1000)));
