title: Sending API request in react native after something is searched in searchbar (react-native-elements)
body: <p>I have a react native search bar and I need to make an api call with the data user typed in the searchbar . but because I do not have a database on mobile device I want to make the request only if user hit search button ( not while user is typing )
  and while we are on that area I also need to know how can I change the font for the placeholder in the searchbar</p>
  
  <p>here is my searchbar code:</p>
  
  <pre><code>  &lt;SearchBar
          placeholder="Something..."
          round
          containerStyle={{
          backgroundColor: 'transparent',
          width: '70%',
          borderTopWidth: 0,
          borderBottomWidth: 0
        }}
          inputContainerStyle={{
          backgroundColor: '#fff'
        }}
          cancelButtonProps={{
          color: '#fff'
        }}/&gt;
  </code></pre>
