Question

I have this button in first screen

 <Button rounded   title='next'    onPress= {() => navigate('nextScreen', { text: this.props.navigation.state.params.text, name: this.props.navigation.state.params.name})}>

and I want to display the text and the name in nextScreen but there is no result , here is the code

 <Text style={{direction: 'rtl', fontSize: 15, padding: 5 }}> • {this.props.navigation.state.params.name}-  {this.props.navigation.state.params.text} </Text>

Answer 1

<Button rounded   title='next'    onPress= {() => navigate('nextScreen', { text: this.props.navigation.state.params.text, name: this.props.navigation.state.params.name})}>

in the above code you are sending text and name as

{ text: this.props.navigation.state.params.text, name: this.props.navigation.state.params.name}

check weather you are getting text and name from the previous screen.the values should not be null
