Use Parent

Use to add parent nesting to the widget.

    ..color =
    ..useParent((v) => v
        ..p = 8
        ..rounded = 8

However, if you're planning to add just 1-2 parents widget, you can just use .n prefix property which indicate that you're intent to the property to the parent.

    ..color =
    ..n.p = 8
    ..n.rounded = 8;

These two is does exactly the same thing, .n prefix is just a syntax sugar to the useParent hook.

Best Practice

  • Use n prefix if you're applying just 1-2 properties to parent
  • Use useParent if you're applying multiple properties to parent
