In this video, we are going to check out how we make sure the widget is visible on the screen when we are dealing with the ScrollView(s).

You can use the `ensureVisible()` method to make your particular widget visible using its unique `Key`.

`ensureVisible()` allows to scroll to the desired widget easily, consider this method only for small predefined lists. As for bigger lists, you'll get performance problems.

Also, this will not work with `ListView` as it won't render non-visible items. Meaning that your widget most likely will not be built at all and your widget will have no context; preventing you from using that method without some more work.
