Screen Navigation Options

Each screen can configure several aspects about how it gets presented in parent navigators.

Two Ways to specify each option

Static configuration: Each navigation option can either be directly assigned:

class MyScreen extends React.Component {
  static navigationOptions = {
    title: 'Great',
  };
  ...

Dynamic Configuration

Or, each option can be a function that takes the following arguments, and returns the value of the option.

• navigation - the navigation prop for the screen, with the screen's route at navigation.state
• childRouter - The child router, if the screen is a navigator

class ProfileScreen extends React.Component {
  static navigationOptions = {
    title: (navigation, childRouter) => {
      return navigation.state.params.name + "'s Profile!";
    },
  };
  ...

Generic Navigation Options

The title navigation option is generic between every navigator. It is used to set the title string for a given screen.

class MyScreen extends React.Component {
  static navigationOptions = {
    title: 'Great',
  };
  ...

Unlike the other nav options which are only utilized by the navigator view, the title option can be used by the environment to update the title in the browser window or app switcher.
