Aligning Navbar Title to Middle and Removing Tab Panel Button

Introduction

When building a user interface, especially with a library like React Navigation that utilizes the navbarPage() component, it’s not uncommon to encounter layout and design issues. In this blog post, we’ll focus on two specific questions: aligning the title of a navbarPage() to be in the middle of the navbar, and removing the square (tab panel button) generated by an empty title argument from another function (tabPanel()).

Understanding navbarPage()

Before diving into the solutions, it’s essential to understand how navbarPage() works. The navbarPage() component is a part of React Navigation and provides a basic navigation bar for your app. It has several props that allow you to customize its appearance and behavior.

Here’s an example:

import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import { MaterialCommunityIcons, FontAwesomeIcon } from 'react-icons';

const Tab = createBottomTabNavigator();

function HomeScreen() {
  return (
    <View>
      <Text>Welcome to Home Screen</Text>
    </View>
  );
}

function ProfileScreen() {
  return (
    <View>
      <Text>Welcome to Profile Screen</Text>
    </View>
  );
}

const navigation = createBottomTabNavigator();

function App() {
  return (
    <NavigationContainer>
      <Tab.Navigator>
        <Tab.Screen name="Home" component={HomeScreen} />
        <Tab.Screen name="Profile" component={ProfileScreen} />
      </Tab.Navigator>
      <navbarPage title="Test Title">
        <View>
          <FontAwesomeIcon icon={MaterialCommunityIcons.Gear} size={24} color="#000" />
        </View>
      </navbarPage>
    </NavigationContainer>
  );
}

In the above example, we have created a basic bottom tab navigator with two screens: Home and Profile. We’ve also added a navbarPage() component at the bottom of the screen.

Aligning Navbar Title to Middle

To align the title of the navbarPage() to be in the middle of the navbar, you need to use CSS to center it horizontally and vertically.

Here’s an example:

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

function App() {
  return (
    <View style={styles.container}>
      <Text style={styles.title}>Test Title</Text>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: '#f2f2f2',
    justifyContent: 'center',
    alignItems: 'center',
    height: 50,
  },
  title: {
    fontSize: 24,
    fontWeight: 'bold',
    color: '#333',
  },
});

In the above example, we’ve created a View component with a style that centers its content both horizontally and vertically using justifyContent and alignItems. We then apply this style to the Text component that contains our title.

We also need to adjust the layout of the navbarPage() component to accommodate the centered title. This can be done by wrapping the title in a container with a fixed width and height, like so:

<navbarPage title="Test Title">
  <View style={styles.container}>
    <Text>Test Title</Text>
  </View>
</navbarPage>

And update the CSS to match:

.test {
  display: flex;
  justify-content: center;
  align-items: center;
}

Removing Tab Panel Button

To remove the square (tab panel button) generated by an empty title argument from another function (tabPanel()), you need to modify the tabPanel() component.

Here’s an example:

<tabPanel>
  <View style={styles.container} />
</tabPanel>

In this example, we’ve replaced the Text component with a View component that takes up no space. This effectively removes the tab panel button.

However, if you want to keep the navigation functionality of the tabPanel() component but remove the visual indicator (the square), you can use a different approach:

<tabPanel>
  <View style={styles.container} />
  <FontAwesomeIcon icon={MaterialCommunityIcons.Gear} size={24} color="#000" />
</tabPanel>

In this example, we’ve added a FontAwesomeIcon component to the tabPanel() component. This will render the navigation indicator (the square) but with a custom icon instead of a default one.

Conclusion

Aligning the title of a navbarPage() to be in the middle of the navbar and removing the tab panel button can be achieved by using CSS and modifying the layout of the navbarPage() component. By understanding how the navbarPage() component works and using the right styles, you can customize its appearance to fit your design needs.

Remember to always keep your code organized and readable, especially when working with complex UI components like navbarPage().
