Installation

Usage

react-native-styled-toast uses styled-components and styled-system under the hood, so please ensure you have these installed in your project. It also makes use of the Constants API from expo-constants, so you will need that too.

Because this component relies on theming, you need to ensure that you've wrapped your app in the ThemeProvider component from styled-components - then use the ToastProvider and wrap the rest of your app:

import { ThemeProvider } from 'styled-components'
import { ToastProvider } from 'react-native-styled-toast'

return (
  <ThemeProvider theme={theme}>
    <ToastProvider>
      <App />
    </ToastProvider>
  </ThemeProvider>
)

Now that your app has access to the Toast context, you can make use of the provided useToast hook to trigger a notification anywhere in your app:

import { useToast } from 'react-native-styled-toast'

const { toast } = useToast()

return <Button onPress={() => toast({ message: 'Check me out!', ...config })} />

If you aren't able to make use of hooks for whatever reason, you can still use the provided ToastContext.Consumer

import { ToastContext } from 'react-native-styled-toast'

return (
  <ToastContext.Consumer>
    {({ toast }) => {
      return (
        <Button
          onPress={() =>
            toast({
              message: 'Woo! This is a success toast.'
            })
          }
          title="Show Success Toast"
        />
      )
    }}
  </ToastContext.Consumer>
)

This component relies on styled-system to access colors from your theme. So you need to ensure that your theme object is configured correctly. Please refer to the styled-system docs. Your theme object should contain at least a spacing scale with some default colors, it should looks something like this:

export default {
  space: [0, 4, 8, 12, 16, 20, 24, 32, 40, 48],
  colors: {
    text: '#0A0A0A',
    background: '#FFF',
    border: '#E2E8F0',
    muted: '#F0F1F3',
    success: '#7DBE31',
    error: '#FC0021'
  }
}

By default, react-native-styled-toast references the following theme color keys for their respective properties:

background (default toast background)
text (default toast text color)
success (default success accent color)
error (default error accent color)
muted (default close button bg color)

If your colors object in your theme does not contain these, you can customize these values in the toast configuration object. E.g:

const { toast } = useToast()

<Button onPress={() => toast({ bg: 'myBgColor', color: 'myTextColor' })} />

Dark Mode Compatible 🌗

Because of the theming capability of react-native-styled-toast, it has out of the box support for dark mode. All you need to do is ensure the color keys you're using for your different modes are the same
