+### Code generation
+
+Code generation is created using `build_runner` package.\
+To configure this package edit the `build.yaml`\
+To add new files to watch for code generation add the following lines:
+```
+targets:
+  $default:
+    builders:
+      # Previous configured builders
+      ...
+      builder_package_name:
+        generate_for:
+          # Example glob for only the Dart files under `lib/models`
+          - lib/models/*.dart
+```
+To create generated code run `clean_up.sh` under [scripts] folder or the following command: `flutter pub run build_runner build --delete-conflicting-outputs`
