When we convert a string to a DateTime object, the structure of the string is crucial. The string should be a subset of the accepted strings for the static DateTime parse method. The accepted strings are in the 'yyyy mm dd' format, offset by an optional time zone. The time zone offset...
class TimeUtils {static String formatDateTime(int timestamp) {var date = DateTime.fromMillisecondsSinceEpoch(timestamp * 1000);var formatter = DateFormat('yyyy-MM-dd HH:mm:ss');return formatter.format(date);}} 这个类有一个静态方法formatDateTime(),它将一个 UNIX 时间戳作为输入,并将其转换为格...
import 'package:intl/intl.dart'; void main() { DateTime dateTime = DateTime.now(); String formattedDate = DateFormat('yyyy-MM-dd HH:mm:ss').format(dateTime); print(formattedDate); // 输出: 例如 2023-04-14 12:34:56 } 遇到的问题及解决方法 ...

类型转换 Number转String 用 12.toString() String转Number用 int.parse(str) 6. var num = 0/0 此时num类型是NaN if(num is NaN) { …… } List的常用方法和属性:注意调用reversed将返回('a','b'), 需要toList(),才能转为List 即就是['a', 'b']. Map常用属性和方法:...
String title, DateTime maxValue, DateTime minValue, DateTime value, DateTimePickerAdapter adapter, @required _DateClickCallBack clickCallback, }) {inttimeType;if(dateType == DateType.YM){ timeType = PickerDateTimeType.kYM; }elseif(dateType == DateType.YMD_HM){ ...

关于toUtc和toLocal两个api返回结果其实都是一个DateTime对象,直接输出调用的是toString方法,所以默认直接调用toString方法返回的是当地时间,如果转为utc后,再调用toString则返回的是utc时间的字符串格式。我们在下面的解析字符串中可以更详细的看到。 解析字符串时间 ...
