android - Different Headers in StackNavigator -

i have implemented stacknavigator in removed header styles purpose.

now have component inside stacknavigator i'd header back. how reckon ?

here stacknavigator :

const nav = stacknavigator( {     splashscreen: {screen: splashscreen},     login: {screen: login},     register: {screen: register},     main: {screen: mainnav}, }, {     headermode: 'none', }); 

but register screen, have header (to let user know can go back).

i tried doing :

static navigationoptions = {     title: 'register',     header: {      } } 

but don't quite know put inside header part.

personally did: had set height of header 0 when didnt want show , n show somenthing height: condition ? 0 : 10

otherwise answered here

you can programmatically following code:

static navigationoptions = ({ navigation }) => ({   header: > (navigation.state.params.thanks) => <headerview > content={navigation.state.params.thanks} /> : null, }) 

and can set state params this:

componentwillmount() {   this.props.navigation.setparams({ thanks:"something" }); } 

although haven't tried code myself , i'm not sure if headerview accessible public api in react-navigation , if there content property on that. think in abstract way, how set programmatically.

i didn't try either might work

edit: answer given in github better, can import headerview react-navigation , header: condition ? headerview : null show , hide
