##
Usage

###
Default components

For quick setup we provide default components, which are React Native Elements Icon for left/right buttons and React Native Text for title. You can customize them with configuration objects passed in as props.

    <Header
      leftComponent={{ icon: 'menu', color: '#fff' }}
      centerComponent={{ text: 'MY TITLE', style: { color: '#fff' } }}
      rightComponent={{ icon: 'home', color: '#fff' }}
    />

###
Custom components passed in through props

You can pass in your custom components like this too.

    <Header
      leftComponent={<MyCustomLeftComponent />}
      centerComponent={<MyCustomCenterComponent />}
      rightComponent={<MyCustomRightComponent />}
    />

###
Mixed components

You can also mix the content, for example you can have default components defined by configuration combined with custom components. Passing a render function that returns a React Element is valid too.

    <Header
      leftComponent={<MyCustomLeftComponent />}
      centerComponent={this.renderCenterComponent()}
      rightComponent={{ icon: 'home', style: { color: '#fff' } }}
    />

###
Custom components passed in as children

    <Header>
      <MyCustomLeftComponent />
      <MyCustomCenterComponent />
      <MyCustomRightComponent />
    </Header>

##
Component precedence

Components defined through props take precedence over components passed in as children, so in this case only the left component with icon set to menu will be rendered.

    <Header leftComponent={{ icon: 'menu' }}>
      <MyCustomLeftComponent />
      <MyCustomCenterComponent />
      <MyCustomRightComponent />
    </Header>

##
Header customisability

We wanted the Header to be as customisable as possible, so you are free to try different combinations of props. For example, if you want to change the left, center, or right component's layout, you can adjust the `innerContainerStyles`

    <Header
      statusBarProps={{ barStyle: 'light-content' }}
      leftComponent={<MyCustomLeftComponent />}
      centerComponent={{ text: 'MY TITLE', style: { color: '#fff' } }}
      outerContainerStyles={{ backgroundColor: '#3D6DCC' }}
      innerContainerStyles={{ justifyContent: 'space-around' }}
    />
