+# Strategy Pattern
+Strategy is a behavioral design pattern that lets you define a family of algorithms, put each of 
+them into a separate class, and make their objects interchangeable.
+
+Tutorial: [here](https://refactoring.guru/design-patterns/strategy).
+

+
+## Client code:
+```dart
+void main() {
+  final byteList = ByteContext()
+    ..add('Hello guru')
+    ..add(123456789)
+    ..add(3.1456564984);
+
+  final strFormat = byteList.toStringView(StrViewStrategy());
+  final hexFormat = byteList.toStringView(HexViewStrategy());
+  final zipFormat = byteList.toStringView(ZipViewStrategy());
+
+  print(strFormat);
+  print(hexFormat);
+  print(zipFormat);
+}
+```
+
+### Output:
+```
+StrViewStrategy:
+Hello guru, 123456789, 3.1456564984
+
+HexViewStrategy:
+Hello guru     : 48 65 6c 6c 6f 20 67 75 72 75

+3.1456564984   : 40 09 2a 4d f4 48 9f 7e
