React Native Snackbar

Material Design "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. */ },
  },
});

Installation

Install:
- Using npm: npm install react-native-snackbar --save
- Using Yarn: yarn add react-native-snackbar
Link:
- react-native link react-native-snackbar
- Or if that fails, link manually using these steps

Import it in your JS:

import Snackbar from 'react-native-snackbar';

Customization

Snackbar.show() accepts the following options:

Key	Data type	Default value?	Description
`title`	`string`	Required.	The message to show.
`duration`	See below	`Snackbar.LENGTH_SHORT`	How long to display the Snackbar.
`action`	`object` (described below)	`undefined` (no button)	Optional config for the action button (described below).
`backgroundColor`	`string` or `style`	`undefined` (natively renders as black)	The background color for the whole Snackbar.

Where duration can be one of the following (timing may vary based on device):

Snackbar.LENGTH_SHORT (just over a second)
Snackbar.LENGTH_LONG (about three seconds)
Snackbar.LENGTH_INDEFINITE (stays on screen until the button is pressed)

And the optional action object can contain the following options:

Key	Data type	Default value?	Description
`title`	`string`	Required.	The text to show on the button.
`onPress`	`function`	`undefined` (Snackbar is simply dismissed)	A callback for when the user taps the button.
`color`	`string` or `style`	`undefined` (natively renders as white)	The text color for the button.

Troubleshooting
