flutter pub add duration基于插件公开信息、社区数据与项目使用情况整理的选型参考。
duration 包提供了一些工具，可简化与 Dart 的 Duration 类一起使用。它能够将持续时间格式化为人类可读的字符串（例如 '2h 30m'），并将此类字符串解析回 Duration 对象。这在用户界面中显示时间间隔或以自然格式接受用户输入的时间时特别有用。该包支持所有主要平台，包括移动、Web 和桌面，非常适合处理时间相关数据的跨平台应用程序。

Utilities to make working with 'Duration's easier.
Use Duration.pretty() method or prettyDuration function to format a duration.
main() {
final dur = Duration(
days: 5,
hours: 23,
minutes: 59,
seconds: 59,
milliseconds: 999,
microseconds: 999,
);
// => 5d, 23h, 59m, 59s
print(dur.pretty());
// => 3 seconds
print((aMillisecond * 3000).pretty());
// => 2 seconds 250 milliseconds
print((aMillisecond * 2250).pretty);
// => 1 day 3 hours 2 minutes
print((aMillisecond * 97320000).pretty());
}
Use locale parameter to format with desired locale.
main() {
// => 5 días 9 horas
final dur = aDay * 5 + anHour * 9;
print(
dur.pretty(
abbreviated: false,
locale: DurationLocale.fromLanguageCode('ru'),
));
}
Use abbreviated parameter to use abbreviated units.
main() {
final dur = Duration(
days: 5,
hours: 23,
minutes: 59,
seconds: 59,
milliseconds: 999,
microseconds: 999,
);
// => 5d, 23h, 59m, 59s, 999ms, 999us
print(dur.pretty(abbreviated: true, tersity: DurationTersity.all));
}
Use spacer to add a string between amount and unit.
main() {
// => 5 whole days 9 whole hours
print((aDay * 5 + anHour * 9).pretty(spacer: ' whole '));
}
Use delimiter to separate each individual part with a string.
main() {
// => 5 days, 9 hours and 10 minute
print((aDay * 5 + anHour * 9 + aMinute * 10).pretty(delimiter: ', '));
}
Use conjugation to add a string before the final unit. Use it in conjunction with
delimiter to add ',' and 'and' to separate individual parts.
main() {
// => 5 days, 9 hours and 10 minutes
print(
(aDay * 5 + anHour * 9 + aMinute * 10).pretty(
delimiter: ', ',
conjugation: ' and ',
));
}
main() {
final Duration dur = parseDuration('245:09:08.007006');
print(dur);
}
main() {
final Duration dur = parseTime('245:09:08.007006');
print(dur);
}
