Overview

A bottom tab navigator is a row of tabs placed at the bottom of the screen, allowing users to switch between different screens with a simple tap.

By incorporating a botton tab navigator, you:

  • Enhance discoverability. Users can quickly identify and access different sections of your app, which ensures that they can find what they're looking for effortlessly.

  • Enable seamless switching between sections. This fluid user experience keeps users engaged and satisfied with your app.

  • Have the freedom to customize the appearance of each tab to match your app's branding and unique requirements.

How to Use Top and Bottom Tab Navigators

In this tutorial, we'll explore the benefits of using a top or bottom tab navigator and provide step-by-step instructions on implementation.

Add a Navigator

To add a navigator to your app:

  1. Click the dropdown arrow at the top of your component tree.

  2. Hover over Add Navigator.

  3. Select the navigator you want to add.

Add and Remove Navigator Tabs

By default, the navigator includes four tabs. You’ll need to identify the sections or views you want to include in your app and add or remove tabs accordingly.

Add a Tab

To add a tab to your navigator, create a new screen and, within the component tree, drag it to nest within the tab navigator component.

Remove a Tab

To remove a tab, delete its corresponding screen in the component tree.

Bottom Tab Navigator Properties

Click on the tab navigator in the component tree to access the navigator’s properties panel. Here, on the right side, you can customize the properties specific to the navigator.

Property
Value
Description

Active Tint Color

Color

Set the text color for the tab the user is currently engaging with.

Active Background Color

Color

Set the background color for the tab the user is currently engaging with.

Inactive Tint Color

Show Label Icon

Dropdown menu

Screen and Tab-Specific Properties

To access the properties panel for a specific tab, click the screen name in the component tree.

Screen

Background Image

Background Image Resize Mode

cover, contain, stretch, repeat, or center

Orientation (iOS and Android only)

portrait, landscape, or auto

Define the screen's orientation.

Picture Resize Mode

  • Center: The image is displayed at its original size within the container, and it is centered both vertically and horizontally. This means that if the image is larger than the container, parts of it may extend beyond the container's edges.

  • Cover: The image is resized to completely cover the container while maintaining its aspect ratio. This mode ensures that the entire container is filled with the image, and any excess image parts are cropped if necessary. This can result in parts of the image being clipped.

  • Contain: The image is resized to fit entirely within the container while maintaining its aspect ratio. This mode ensures that the entire image is visible within the container, and it may result in empty space around the image if the container's aspect ratio differs from the image's aspect ratio.

  • Repeat: The image is tiled or repeated to fill the entire container, both horizontally and vertically. This mode is often used for creating patterns or backgrounds that seamlessly repeat across the container.

  • Stretch: The image is resized to fully cover the container without maintaining its original aspect ratio. This can distort the image and may result in an unnatural appearance, so it's generally not recommended for most scenarios.

Tab Navigation Options

Screens within a navigator have an additional section in the screen's properties panel for navigation options. This is where you define the screen's label that displays in the navigator.

Color (Android only)

Color

Translucent (Android only)

True/False
