如何将带日期的字符串转换为日期时间？ 颤振/飞镖

Question

我有一个字符串，里面有 4 个日期

I/flutter (27269): 2022-08-01 13:08
I/flutter (27269): 2022-08-01 12:54
I/flutter (27269): 2022-08-01 11:46
I/flutter (27269): 2022-07-13 12:42

我想将它转换为 DateTime，我试过这个 DateTime.parse("myStringName"); 但它只存储最后一个日期。

Answer 1

这应该有效：

void main(){
  const myString='I/flutter (27269): 2022-08-01 13:08 I/flutter (27269): 2022-08-01 12:54 I/flutter (27269): 2022-08-01 11:46 I/flutter (27269): 2022-07-13 12:42';

  final myStrings=myString.split('I/flutter (27269): ')..removeAt(0);

  for(final dateString in myStrings){
    var myDateString=dateString.replaceAll('-', '').trim();
    print(DateTime.parse(myDateString));
  }
}

Answer 2

const String firstDate = '2012-02-27 13:27'; 
const String secondDate = '2002-02-27 14:05';

final date1 = DateTime.tryParse(firstDate);
print(date1);

final date2 = DateTime.tryParse(secondDate);
print(date2);

Output：

2012-02-27 13:27:00.000

2002-02-27 14:05:00.000
