JSON Extensions #
You can use an interface or abstract class with instance methods for toJson and factory or regular methods for fromJson. Here’s a revised approach:
User user = User(name: 'Alice', age: 28);
String userJson = serialize(user);
print('Serialized User: $userJson');

User deserializedUser = deserialize<User>(userJson, User.fromJson);
print('Deserialized User: ${deserializedUser.name}');

print(myNumber.reFormat(formatDigits: '000', asFixedNumber: 3)); // Using the extension method

Work with DateTime formatting easily:
DateTime now = DateTime.now();
print('Standard DateTime: ${now.format(pattern: PredefinedDateFormats.standardDateTime.pattern)}');
print('Date Only: ${now.format(pattern: PredefinedDateFormats.dateOnly.pattern)}');
print('Time Only: ${now.format(pattern: PredefinedDateFormats.timeOnly.pattern)}');
print('Custom DateTime: ${now.format(pattern: PredefinedDateFormats.customDateTime.pattern)}');
print('Verbose DateTime with Day of Week: ${now.format(pattern: PredefinedDateFormats.verboseDateTimeWithDayOfWeek.pattern)}');
print('Year and Full Month: ${now.format(pattern: PredefinedDateFormats.yearAndFullMonth.pattern)}');

Date Time Utils Extensions #
Work with DateTime formatting easily:
DateTime today = DateTime.now();
print('Today is ${today.isLeapYear ? "a" : "not a"} leap year.');
print('Days in the current month: ${today.daysInMonth}');
print('Is today the start of the year? ${today.isStartOfYear}');
print('Is today the end of the year? ${today.isEndOfYear}');
print('Days to the end of the year: ${today.daysToEndOfYear}');
print('Is today a weekend? ${today.isWeekend}');
