Color in status bar with React Native and react-navigation

I am using react-navigation in React Native and I have changed the header color with

const MyScreenNavigator = StackNavigator({
  ...
}, {
  navigationOptions: {
    headerStyle: {
      backgroundColor: 'blue',
    },
    headerTintColor: 'white'
  }
});

It does change the background color of both header and status bar, but the font color is still black in the status bar.

How can I customise the font color of the status bar?
