100% width in React Native Flexbox

Question

I have already read several flexbox tutorial, but I still cannot make this simple task to work.

How can I make the red box to 100% width?

Code:

Answer 1

Use javascript to get the width and height and add them in View's style. To get full width and height, use Dimensions.get('window').width https://facebook.github.io/react-native/docs/dimensions.html

getSize() {
    return {
        width: Dimensions.get('window').width, 
        height: Dimensions.get('window').height
    }
}

and then,
