flutter pub add duration根據套件公開資料產生的選型評估，僅供參考。
duration 套件提供工具來簡化與 Dart 的 Duration 類一起使用。它能將持續時間格式化為人類可讀的字串（例如 '2h 30m'），並把這種字串解析回 Duration 物件。這在使用者介面中顯示時間間隔或以自然格式接受使用者輸入時間時特別有用。此套件支援所有主要平台，包括行動裝置、網頁和桌面，非常適合處理時間相關資料的跨平台應用程式。

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);
}
