Text Input

This one's easy.

Add a new custom SearchBar component to your Pokedex container. To complete it, you'll need to use a native TextInput, which works similarly to the web input you should be familiar with, tracking a value and responding to onChangeText events:

<TextInput style={ styles.input }
        value={ query }
        onChangeText={ text => onChange(text) } />

Also note the use of onChangeText which provides the text value as opposed to onChange which provides an event.
