package:basics provides DateTime extensions that can easily compare DateTime objects.

(Disclosure: I contributed those particular extensions.)

You should try this it should work 

````
var date1 = DateTime.parse('2020-01-13').millisecondsSinceEpoch.toInt();
var date2 = DateTime.parse('2021-01-15').millisecondsSinceEpoch.toInt();
if(date1 < date2){
    print('true');
}else{
    print('false');
}
````

Instead of doing that just use the date's isBefore or isAfter operator

It would look something like the following:

final now = DateTime.now();
final yesterday = DateTime.now().subtract(Duration(days: 1));
print(now.isAfter(yesterday));  //true

Since your dates are in STring format, it you would have to use the DateTime.parse() method to construct your date objects, and then use the operators talked about above
