Why is dynamic header not working in react-native?

Question

React

In this https://reactnavigation.org/docs/intro/ example, the dynamic header should work something like this:

static navigationOptions = ({ navigation }) => ({
    title: `Chat with ${navigation.state.params.user}`,
  });

but the function is not called at all.

Answer 1

Try like this:

...
componentWillMount() {
   this.props.navigation.setParams({  user: "name"  });
}
...

And see what happens. If everything remains the same, then I think it will be more efficient to look for a solution in the repository: https://github.com/react-community/react-navigatio...
