+
+**Pair** is a simple object which contains pair of two values.

+## Extensions
+
+This package also provides extensions for Dart types.
+
+- Object
+  - isNull
+  - isNotNull
+  - log
+- Iterable
+  - isNullOrEmpty
+  - isNotNullOrEmpty
+  - For bytes iterables
+    - toTypedList
+    - toStr
+- String
+  - isNullOrEmpty
+  - isNotNullOrEmpty
+  - toBytes
+
+String 🔁 Uint8List works with encoding:
+
+```dart
+const String myString = 'abc';
+final Uint8List bytes = myString.toBytes(from : Encoding.utf16);
+print(bytes.toStr(to : Encoding.utf16)); // prints 'abc'
+```
+
+- DateTime
+  - fromSecondsSinceEpoch
+  - secondsSinceEpoch
+  - timestamp
+  - tomorrow
+  - yesterday
+  - today
+  - add/sub/set
+  - nextDay
+  - previousDay
+  - nextMonth
+  - previousMonth
+  - nextYear
+  - previousYear
+  - nextWeek
+  - previousWeek
+  - isFuture
+  - isPast
+  - isLeapYear
+  - format
+  - operators
+
+The date formatter works with `String` formatter:
+
+```dart
+final DateTime date = DateTime(1999, 6, 30);
+print(date.format([dd, '/', mm, '/', yy])); // prints '30/06/99'
+```
