I'm quite new with React native. I want to set information include Add, Edit and Show detail on one screen, so I set state for each event when it's called.

When adding, I set isAdding, when editing, I set isEditing and when show details I set isShowDetail and navigate them, like this.

Screen A:

this.props.navigation.navigate(ROUTE_INVOICE_DETAIL_NAME, invoice, isEditing: true );

and Screen B (Details):

constructor(props) {
 super(props);
 this.isShowDetail = props.navigation.getParam("isShowDetail");
 console.log(this.isShowDetail);
 this.isAdding = props.navigation.getParam("isAdding")
 this.isEditing = props.navigation.getParam("isEditing");
 const params = = this.props.navigation.state;
 const invoice = = params;
 const paid = 0, incurred = 0, transportFee = 0, id = invoice;
 this.state = 
 id,
 invoice,
 isShowTicketDetail: false,
 customer: ,
 paid,
 incurred,
 transportFee,
 details: ,
 ;

I don't know how to get isEditing and isAdding value, it returns undefined.

ROUTE_INVOICE_DETAIL_NAME is declared and I'm sure that it goes to Detail.

  It looks like you're using react-navigation? I'd expect props.navigation.getParam("isEditing") to get you what you want. The getParam method is a helper, and you can also see all navigation params from props.navigation.state.params -- you might try to console.log(props.navigation.state.params) and see if what you expect is there.

  Also, this is a style detail for you: But it looks like you sometimes set isEditing, sometimes set isAdding, and sometimes set isShowDetail. It wouldn't ever make sense for none of these to be set, and it wouldn't ever make sense for two or three of them to be set. I'd probably have a string param called mode or something, and set it to SHOW_DETAIL, CREATE, and EDIT. Then you don't need to check 3 different booleans, but can just check for 3 different cases of the one field.

On Screen A:

this.props.navigation.navigate(ROUTE_INVOICE_DETAIL_NAME, 
 invoice_data: invoice ,
 isEditing: true
 )

On Screen B you can get data like this :

let invoice_data = this.props.navigation.state.params.invoice_data
let isEditing = this.props.navigation.state.params.isEditing
