如何将 "MM/DD/YYYY" 转换为 TZDateTime 格式
How to convert "MM/DD/YYYY" to TZDateTime format
我正在我的待办事项应用程序中实现 flutter 本地通知插件,我想安排
特定日期和时间的通知,日期选择器和时间选择器显示日期如下:12/26/2021 时间如下:03:17 PM ,如何将其转换为 TZDateTime 格式
试试下面的代码
TZDateTime tzDateTime;
String dateTime = getFormattedDateFromFormattedString(
value: "12/26/2021 3:16 PM",
currentFormat: "MM/dd/yyyy hh:mm a",
desiredFormat: "yyyy-MM-dd HH:mm:ss");
tz.initializeTimeZones();
tzDateTime = tz.TZDateTime.parse(tz.local, dateTime);
print(tzDateTime);
}
// format your given time
getFormattedDateFromFormattedString(
{value, String currentFormat, String desiredFormat, isUtc = true}) {
DateTime dateTime = DateTime.now();
if (value != null || value.isNotEmpty) {
try {
dateTime = DateFormat(currentFormat).parse(value, isUtc).toLocal();
} catch (e) {
print("$e");
}
}
return dateTime.toString();
}
导入时区
import 'package:timezone/data/latest_all.dart' as tz;
import 'package:timezone/timezone.dart' as tz;
tz.initializeTimeZones();
tz.TZDateTime.parse(tz.local, "2012-12-26 03:17:00");
//tz.UTC
或者
tz.TZDateTime.from(DateTime(2021,12,26,03,07), tz.local);
//tz.UTC
