Moving from stack to bottomTabs make topBar disappear in react-native-navigation 2


I create a dummy project to learn. So, I create a dummy login page with a button that redirects me to the main app, which it is a bottomTabs app. The Login screen has the topBar visible, but then when I click the button to be redirected, I can't see any topBar, even when I defined it.

This is my App.js

import { Navigation } from 'react-native-navigation';

import AuthScreen from './src/screens/Auth/Auth';
import FindPlaceScreen from './src/screens/FindPlace/FindPlace';
import SharePlaceScreen from './src/screens/SharePlace/SharePlace';

// Register screens
Navigation.registerComponent("awesome-places.AuthScreen", () => AuthScreen);
Navigation.registerComponent("awesome-places.SharePlaceScreen", () => SharePlaceScreen);
Navigation.registerComponent("awesome-places.FindPlaceScreen", () => FindPlaceScreen);


// Start the app
Navigation.events().registerAppLaunchedListener(() => {
    Navigation.setRoot({
        root: {
            stack: {
                children: [
                    {
                        component: {
                            name: 'awesome-places.AuthScreen',
                            options: {
                                topBar: {
                                    title: {
                                        text: 'Título'
                                    }
                                }
                            }
                        }
                    }
                ],
            }
        }
    });
});

My AuthScreen component is this one:

import React, {Component} from 'react';
import { Button, View, Text, StyleSheet } from 'react-native';
import startMainTabs from './../MainTabs/startMainTabs';

export default class AuthScreen extends Component {

    loginHandler = () => {
        startMainTabs();
    }

    render() {
        return (
            <View style={styles.container}>
                <Text>AuthScreen</Text>
                <Button title="Login" onPress={this.loginHandler}/>
            </View>
        );
    }

}

const styles = StyleSheet.create({

    container: {
        margin: 25
    }

});

And the main tabs code is:

import { Navigation } from 'react-native-navigation';
import Icon from 'react-native-vector-icons/Ionicons';

const startTabs = () => {
    Promise.all([
        Icon.getImageSource('md-map', 30),
        Icon.getImageSource('ios-share-alt', 30)
    ]).then((res) => {
        Navigation.setRoot({
            root: {
                bottomTabs: {
                        children: [
                            {
                                component: {
                                    name: 'awesome-places.SharePlaceScreen',
                                    options: {
                                        topBar: {
                                            visible: true,
                                            title: {
                                                text: 'Título'
                                            }
                                        },
                                        bottomTab: {
                                            fontSize: 12,
                                            text: 'A',
                                            icon: res[0],
                                        }
                                    }
                                },
                            },
                            {
                                component: {
                                    name: 'awesome-places.FindPlaceScreen',
                                    options: {
                                        topBar: {
                                            visible: true,
                                            title: {
                                                text: 'Título'
                                            }
                                        },
                                        bottomTab: {
                                            fontSize: 12,
                                            text: 'B',
                                            icon: res[1],
                                        }
                                    }
                                },
                            },
                        ],
                },
            }
        });
    })
}

export default startTabs;

If this help, the components that I'm calling are exactly the same, and the code is like this:

import React, {Component} from 'react';
import { View, Text, StyleSheet } from 'react-native';

export default class FindPlaceScreen extends Component {

    render() {
        return (
            <View style={styles.container}>
                <Text>Find Place</Text>
            </View>
        );
    }

}

const styles = StyleSheet.create({

    container: {
        margin: 25
    }

});

The environment that I'm currently using is:


Solution

  • I modify my stratMainTabs file to:

    import { Navigation } from 'react-native-navigation';
    import Icon from 'react-native-vector-icons/Ionicons';
    
    const startTabs = () => {
        Promise.all([
            Icon.getImageSource('md-map', 30),
            Icon.getImageSource('ios-share-alt', 30)
        ]).then((res) => {
            Navigation.setRoot({
                root: {
                    bottomTabs: {
                        children: [
                            {
                                stack: {
                                    children: [
                                        {
                                            component: {
                                                name: 'awesome-places.SharePlaceScreen',
                                                options: {
                                                    topBar: {
                                                        animate: false,
                                                        visible: true,
                                                        title: {
                                                            text: 'Título A'
                                                        }
                                                    },
                                                    bottomTab: {
                                                        fontSize: 12,
                                                        text: 'A',
                                                        icon: res[0],
                                                    }
                                                }
                                            },
                                        }
                                    ]
                                }
                            },
                            {
                                stack: {
                                    children: [
                                        {
                                            component: {
                                                name: 'awesome-places.FindPlaceScreen',
                                                options: {
                                                    topBar: {
                                                        animate: false,
                                                        visible: true,
                                                        title: {
                                                            text: 'Título B'
                                                        }
                                                    },
                                                    bottomTab: {
                                                        fontSize: 12,
                                                        text: 'B',
                                                        icon: res[1],
                                                    }
                                                }
                                            },
                                        }
                                    ]
                                }
                            },
                        ],
                    },
                }
            });
        })
    }
    
    export default startTabs;
    

    Basically I put the children elements inside and stack, and inside that stack I added the tabComponent. And that solves the problem. Could someone please could share why this is working?
