<p>In this example, we store <code>text</code> in the state, because it changes over time.</p>
|
||
<p>There are a lot more things you might want to do with a text input. For example, you could validate the text inside while the user types. For more detailed examples, see the <a href="https://reactjs.org/docs/forms.html#controlled-components">React docs on controlled components</a>, or the <a href="/react-native/docs/textinput">reference docs for TextInput</a>.</p>
|
||
<p>Text input is one of the ways the user interacts with the app. Next, let's look at another type of input and <a href="/react-native/docs/handling-touches">learn how to handle touches</a>.</p>
