+Simplify your code is not the only benefit of using such package.
+The chain-style programming also makes comment to cancel code easier:
+such as you can simply cancel a line to remove a layer of widget,
+and when you want to use them again, you can simply cancel the comment
+to add them back to your code, that you don't need to worry about the indents.
+For example:
+
+```dart
+import 'package:flutter/widgets.dart';
+import 'package:wrap/wrap.dart';
+
+class App extends StatelessWidget {
+  const App({super.key});
+
+  @override
+  Widget build(BuildContext context) => 'app root'
+      .textWidget
+      // .wrapCenter
+      // .wrapFontSize(23)
+      .wrapForeground(context, const Color(0xffbcbebf))
+      .wrapBackground(const Color(0xff232425))
+      .ensureTextEnvironment(context);
+}
