Flutter's date_format package is a library that provides a convenient way to format dates.

To use the date_format package, add the following line to your pubspec.yaml file:

dependencies: 
  date_format: ^2.0.0

Next you can start using it by importing it in your code:

import 'package:date_format/date_format.dart';

Formatting Dates

The most common use case for the date_format package is to format dates. You can format a date using the format method of the DateFormat class.

Here's an example of how to use the Formatting Dates :

DateTime now = DateTime.now();
String formattedDate = formatDate(now, [yyyy, '-', mm, '-', dd]);
print(formattedDate);

In the example above,

We create a new DateTime object with the current date and time using the DateTime.now() method. We then create a new formatDate object with the format string [yyyy, '-', mm, '-', dd]. This format string specifies that we want the date to be formatted in the year-month-day format, with the year represented by four digits (yyyy), the month represented by two digits (MM), and the day represented by two digits (dd). Finally, we call the format method on the formatDate object with the DateTime object as its argument to get the formatted date string.

The output of the above code will be a string that looks something like this:

2023-03-15

You can also format dates in other formats. Here are some examples:

DateTime now = DateTime.now(); 
String formattedDate = formatDate(now, [DD, ', ',  MM, ' ',  dd, ', ',  yyyy]);

Format the date in the [DD, ', ', MM, ' ', dd, ', ', yyyy] format,

Formatting Times

You can also use the date_format package to format times. To format a time, you can use the Hms format string, which will format the time in hours, minutes, and seconds.

Here's an example of how to use the Formatting Times:

DateTime now = DateTime.now();
String formattedTime = formatDate(now,[HH, ':', nn, ':', ss]);
print(formattedTime);

In the example above, format the time in the [HH, ':', nn, ':', ss] format,

12:34:56

You can also format times in other formats. Here are some examples:

DateTime now = DateTime.now(); 
String formattedTime = formatDate(now,[hh, ':', nn, ' ', am]);

In the example above, we format the time in the [hh, ':', nn, ' ', am] format,

12:34 PM

Conclusion

In summary, the date_format package in Flutter provides a convenient way to format dates and times in various formats. By using the DateFormat class, you can easily format dates and times in the way that you want.
