Perhaps you need specify the timeformat before parsing. So you could try replacing

DateTime stdt = DateTime.parse(postList.startDate.toString());
DateTime endt = DateTime.parse(postList.endDate.toString());

with

DateTime stdt = DateFormat("dd-MM-yyyy").parse(postList.startDate.toString())); 
DateTime endt = DateFormat("dd-MM-yyyy").parse(postList.endDate.toString()));

DateFormat().format( returns a string .

You have to parse the string to date .

final formattedString =DateFormat('dd-MM-yyyy').format(DateTime.now());
final myDate = DateTime.parse(formattedString)
