Render global footer in react-native-router-flux 3

问题:

I have an app where on all scenes I want to render a global navigation footer at the bottom of the screen. This was a very easy thing to do in RNRF 2.x with the footer prop, but I'm having quite a lot of trouble implementing it in 3.x since the footer prop does not exist anymore. Anyone know how to go about doing this?

You can do this with only React Native. Just wrap your old main component in a new View that contains the old main component and the footer. Then the footer will always be shown.

Assuming you have a main component named MainComponent in a file path/to/main/component.js:

// path/to/main/component.js
export default class MainComponent extends React.Component {
    ...
}

Just change it to this:

// path/to/main/component.js
class MainComponent extends React.Component {
    ...
}

export default () => (
    <View styles={styles.newMainComponent}>
        <MainComponent />
        <GlobalFooter />
    </View>
);

You may need to move some styles from your old main component to the new view that wraps it.
