React Native Snackbar

Material Design "Snackbar" component for Android and iOS. Supports custom colors, fonts, background, position and languages.

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({
  text: "Hello world",
  duration: Snackbar.LENGTH_SHORT,
});

to include an action button:

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

maybe you need change the position:

Snackbar.show({
  text: "Hello world",
  duration: Snackbar.LENGTH_INDEFINITE,
  position: Snackbar.POSITION_TOP,
});

Also you can set a image as background:

Valid formats: jpg, png, svg

Snackbar.show({
  text: "Hello world",
  duration: Snackbar.LENGTH_INDEFINITE,
  backgroundImage: "your image location",
});

Installation

Install:
- Using npm: npm install rn-snackbak --save
- Using Yarn: yarn add rn-snackbak
Link:
- RN >= 0.60 supports autolinking: first cd ios && pod install && cd ..
- RN < 0.60: react-native link rn-snackbak
- Or if that fails, link manually using these steps
- Note that because this is a native module, Expo does not support it -- to use with Expo you need to eject to ExpoKit
Import it in your JS:
```
import Snackbar from "rn-snackbak";
```
