NepaliDateTime gorkhaEarthQuake = NepaliDateTime.parse('2072-01-12T11:56:25');
print(gorkhaEarthQuake.year); // 2072
NepaliDateTime currentTime = NepaliDateTime.now();
print(currentTime.toIso8601String()); //2076-02-01T11:25:46.490980
print(gorkhaEarthQuake.mergeTime(10, 20, 30));
// 2072-01-12 10:20:30.000Date Conversion
Converts dates from AD to BS and vice versa.
NepaliDateTime nt = DateTime(2019, 8, 03, 14, 30, 15).toNepaliDateTime();
print('In BS = $nt'); //2076-04-18 14:30:15.000
DateTime dt = nt.toDateTime(); //2019-08-03 14:30:15.000
print('In AD = $dt');Nepali Date Formatter

Nepali Number
Converts English numbers into Nepali number literals.
var currencyFormat = NepaliNumberFormat(
symbol: 'Rs.',
);
var commaSeparated = NepaliNumberFormat(
decimalDigits: 2,
);
var inWords = NepaliNumberFormat(
inWords: true,
language: Language.NEPALI,
);
var currencyInWords = NepaliNumberFormat(
inWords: true,
language: Language.NEPALI,
isMonetory: true,
decimalDigits: 2,
);
print('123456 -> ${currencyFormat.format(123456)}');
// 123456 -> 1,23,456
print('123456789.6548 -> ${commaSeparated.format(123456789.6548)}');
// 123456789.6548 -> 12,34,56,789.65
print('123456 -> ${inWords.format(123456)}');
// 123456 -> 1 lakh 23 thousand 4 hundred 56
print('123456789.6548 -> ${currencyInWords.format(123456789.6548)}');
// 123456789.6548 -> १२ करोड ३४ लाख ५६ हजार ७ सय ८९ रुपैया ६५ पैसाNepali Unicode
Converts English literal (Roman Literals) into Nepali Unicode.
print(NepaliUnicode.convert("sayau' thu''gaa fUlakaa haamii, euTai maalaa nepaalii"));
print(NepaliUnicode.convert("saarwabhauma bhai failiekaa, mecii-mahaakaalii\n"));
// सयौं थुँगा फूलका हामी, एउटै माला नेपाली
// सार्वभौम भै फैलिएका, मेची-महाकालीIf live conversion is required i.e. conversion as you type, then set live: true.
NepaliUnicode.convert(textFromTextField, live: true);Nepali Moment
Generates a fuzzy timestamp using dates provided.
print(NepaliMoment.fromBS(NepaliDateTime.parse('2076-03-22T08:41:14')));
// २२ दिन पछिHere, the current DateTime is 2076-02-32 19:09:25 i.e. reference date
print(NepaliMoment.fromBS(NepaliDateTime.parse('2076-02-32T18:25:14'),
referenceDate: NepaliDateTime.parse('2076-02-32T18:34:14')));
// ९ मिनेट पहिले
print(NepaliMoment.fromAD(DateTime.parse('2019-06-02T18:22:14'),
referenceDate: DateTime.parse('2019-06-15T18:34:14')));
