CupertinoSearchTextField

CupertinoSearchTextField is a CupertinoTextField that looks and behaves like the UISearchTextField of iOS. It is very easy to use, so let’s get started!

First, there is the controller property. This is for controlling the text field and getting the text that the user input. You can also call different functions when something has changed with onChanged, when the user submitted the field with onSubmitted or when the user clicks the X-Mark (suffix) with onSuffixTab. Of course, there is onTap too, that is called for each distinct tap.

Okay, great, this was all that we need to know about functionality for now. Now, let’s talk about UI and UX.

With backgroundColor you can set the background color, borderRadius sets the border-radius, you can set the BoxDecoration with decoration, set the padding and set the TextStyle with textStyle. There is also placeholder and placeholderStyle to customize the placeholder.

Great, these were quite basic properties. But now we want to customize our prefix icon (usually a magnifier icon) and our suffix icon (usually a X). But you can change the icons with prefixIcon and suffixIcon. prefixInsets and suffixInsets set the padding insets for the prefix & suffix. Lastly, there is suffixMode, which dictates when the suffix should be visible and itemColor to set the prefix & suffix color.

Great. Now let’s talk about the last important properties. autocorrectdetermines whether to autocorrect or not and autofocus determines whether this text field should focus itself if nothing else is already focused. You can enable/disable the search text field with enabled.

Great! There are some other properties, but we won’t talk about them in this article. Let’s take a look at an example.
