How can we center title of react-navigation header?

Warning: react-navigation changes a lot, the way to do title align, already changed for like 2-3 times from my first answer of it.

In year of 2020, headerLayoutPreset was also deprecated. The new way is via defaultNavigationOptions: (@ThatFrenchComputerGuy’s answer helped me)

const AppNavigator = createStackNavigator({
    Home: { screen: HomeScreen },
 }, 
 {
  defaultNavigationOptions: {
      title: 'Aligned Center',
      headerTitleAlign: 'center'
  }
});

In year of 2018, after react-navigation v2 release (7 Apr 2018), for some reason alignSelf was not working anymore. Here it is the new working way, using headerLayoutPreset. from @HasanSH:

const HomeActivity_StackNavigator = createStackNavigator({
    Home: {screen: Main},
}, {headerLayoutPreset: 'center'});

Use headerTitleStyle:

static navigationOptions = {
    headerTitleStyle: { alignSelf: 'center' },
    title: 'Center Title',
}
