getDaysBetween static method

int getDaysBetween(
  1. int t1,
  2. int t2
)

t1 : eg: DateTime.now().millisecondsSinceEpoch) 返回相差的天数的整数部分的值（t1比t2差几天，前天就是-2，昨天就是-1，明天就是1）

Implementation

static int getDaysBetween(int t1, int t2) {
  DateTime time1 = DateTime.fromMillisecondsSinceEpoch(t1);
  DateTime time2 = DateTime.fromMillisecondsSinceEpoch(t2);
  Duration diff = time1.difference(time2);
  var diffDays = diff.inDays;
  return diffDays;
}
