添加更多语言
1. 添加语言 i18n 文件
Fork 这个项目，在 lib/src/i18n/ 目录下添加语言文件，例如 strings_en_us.dart。
/// English (EN) United States
class _StringsEnUs extends _StringsI18n {
const _StringsEnUs();
@override
String getCancelText() {
// TODO return cancel widget's text
return null;
}
@override
String getDoneText() {
// TODO return done widget's text
return null;
}
@override
List<String> getMonths() {
// TODO return the array of month's full name [January, February ... December]
return null;
}
@override
List<String> getMonthsShort() {
// TODO return the array of month's short name [Jan, Feb ... Dec]. If return null, will substring the full name (max length is 3)
return null;
}
@override
List<String> getWeeksFull() {
// TODO return the array of week's full name [Monday, Tuesday ... Sunday]
return null;
}
@override
List<String> getWeeksShort() {
// TODO return the array of week's short name [Mon, Tue ... Sun]
return null;
}
}
2. 添加区域设置
在 lib/src/i18n/date_picker_i18n.dart 文件中添加语言区域设置。
enum DateTimePickerLocale {
/// English (EN) United States
en_us,
}
3. 添加区域设置-语言关系
在 lib/src/i18n/date_picker_i18n.dart 文件中添加语言-区域设置关系。
const Map<DateTimePickerLocale, _StringsI18n> datePickerI18n = {
DateTimePickerLocale.en_us: const _StringsEnUs(),
};
