How to Get 1 Day Before Today:

DateTime today = DateTime.now();

DateTime today = DateTime.now();
print(today); //2023-01-16 09:51:27.494057

DateTime yes1 = today.subtract(Duration(days: 1, hours: 4, minutes: 30));
print(yes1); //2023-01-15 05:21:27.494057

How to Get Week ago From Current Time:

print(weeksago); //2023-01-09 09:51:27.494057
