React Native Material Snackbar

Material Design 2.0 "Snackbar" component for Android and iOS.

Snackbars are used for displaying a brief message to the user, along with an optional action. They animate up from the bottom of the screen and then disappear shortly afterward.

See Google's Material Design guidelines for more info on Snackbars and when to use them.

How it works

Snackbar.show({
  title: 'Hello world',
  duration: Snackbar.LENGTH_SHORT,
});

Or, to include an action button:

Snackbar.show({
  title: 'Hello world',
  duration: Snackbar.LENGTH_INDEFINITE,
  action: {
    title: 'UNDO',
    color: 'green',
    onPress: () => { /* Do something. */ },
  },
});

1. Install:

   • Using npm: npm install react-native-material-snackbar --save
   • Using Yarn: yarn add react-native-material-snackbar

2. Link:

   • react-native link react-native-material-snackbar
   • Or if that fails, link manually using these steps
