0.0.4. react-native-vector-icons peer installation failed

The react-native-vector-icons is always not installed.
I follow up the installation instruction by using rnpm link.
But this doesn't seem to link the package correctly.
Probabilities:
  1. This might be the problem if your rootProject name is not correct at all places.
  2. rnpm link might not work all the time.
    • In case of android
    • If React Native version in your app >= 0.29

Solution 1:
Check your rootProject name in react-native-vector-icons's font.gradle, in case if its hard coded there. This causes failure in linking because the rootProject name may not be same with the definition in settings.gradle.
Solution 2: Please complete the installation procedure for react-native-vector-icons by taking up the manual setup mentioned in the docs.



0.0.5. How to override style in NativeBase?

I didn't find a way to override style.
How can I include React StyleSheet into my app?

Solution:
NativeBase is built on top of React Native.
Hence with any component you can pass the style property which will be merged to the default style of that component.
Example: 
<Button style={{backgroundColor: '#FF0000'}}>
        Click me!</Button>



0.0.6. How do I add events with the components?

What events are available for the components?
Example buttons, list items etc.

Solution:
The NativeBase components are built on top of React Native components. Hence the callback events of React Native holds good with NativeBase components.
Example: The Button component is actually a wrapper of the TouchableOpacity component of React Native. So you can just use the onPress callback function for event handling.

Refer the cheatsheet for more details.
