将字符串转换为颤振中的日期列表

Question

我有字符串：

String datesString= "[2022-04-14 15:51:10,2022-01-29 15:51:10]";

我需要将其转换为 DateTime 或 String 列表....

我试试 JsonDecode

List datesList= jsonDecode(datesString);

它抛出格式异常：

Unhandled Exception: FormatException: Unexpected character (at character 6)

[2022-04-14 15:51:10,2022-01-29 15:51:10]

如何从字符串中获取列表？

Answer 1

获取字符串列表：

datesString = datesString.substring( 1, datesString.length - 1);  
var list = datesString.split(",");

要获取 DateTimes 列表，请添加到上面：

var listDates = [];
  
for (var i in list){
  listDates.add(DateTime.parse(i));
}

Answer 2

var date = datesString.toString().replaceAll("]", "").replaceAll("[", "");
List datesList = date.split(",");

列表将是日期列表

或者你可以这样做

 datesString = datesString.substring(1, datesString.length - 1);
List datesList = datesString.split(",");

Answer 3

那个字符串不是JSON。

final dates = datesString.substring(1, datesString.length - 1)
  .split(',')
  .map((date) => DateTime.parse(date));
