How to call Screen / Component class method from react-navigation Header

Question

I need to call SearchScreen class method from a React Navigation Header.

The Navigator look like this:

  Search: {
    screen: SearchScreen,
    path: \'         


        

Answer 1

I've made it work by doing:

// declare static navigationOptions in the Component
static navigationOptions = {
  title: 'Title',
  header: ({ state }) => ({
    right: (
      
    ),
  }),
}

_handleFilterPress() {
  // do something
}


componentDidMount() {
  // set handler method with setParams
  this.props.navigation.setParams({ 
    handleFilterPress: this._handleFilterPress.bind(this) 
  });
}
