@rn-nui/alert

@rn-nui/alert

Native alerts for React Native with enhanced functionality and cross-platform support.

Installation

npm install @rn-nui/alert

or

yarn add @rn-nui/alert

iOS Setup

No additional setup required for iOS.

Android Setup

You'll need to override the theme of your app under /android/app/src/main/res/values/styles.xml to something that inherits from Material3 or Material3Expressive.

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.Material3.DayNight.NoActionBar">
      <!-- Customize your theme here -->
    </style>
</resources>

Android Colors Customization

You'll need to follow the M3 guidance around dialogs and inputs. When you locate the color token you'd like to change, override it in your colors.xml or styles.xml file.

Expo Setup

There is no plugin for Expo yet. You'll need to manually edit the native files as described above.

Icons for Android Alerts

You'll need to add the icons you want to use under /android/app/src/main/res/drawable and reference them by the file name in your alert options. For example, if you add the file base_cookie_24.xml, you can use it like this:

Alert.alert('Title', 'Message', buttons, { icon: 'base_cookie_24' });

Note: If you use vectors directly from Android Studio, update the tint color like this: android:tint="?attr/colorSecondary". This will follow the M3 specs and ensure the icon color matches the night or day theme.

import Alert from '@rn-nui/alert';

// Basic alert
Alert.alert('Title', 'Message');
