CupertinoSearchTextField class Null safety

A CupertinoTextField that mimics the look and behavior of UIKit's UISearchTextField.

This control defaults to showing the basic parts of a UISearchTextField, like the 'Search' placeholder, prefix-ed Search icon, and suffix-ed X-Mark icon.

To control the text that is displayed in the text field, use the controller. For example, to set the initial value of the text field, use a controller that already contains some text such as:

This examples shows how to provide initial text to a CupertinoSearchTextField using the controller property.
To create a local project with this code sample, run:
flutter create --sample=cupertino.CupertinoSearchTextField.1 mysample

It is recommended to pass a ValueChanged<String> to both onChanged and onSubmitted parameters in order to be notified once the value of the field changes or is submitted by the keyboard:
