Get Started

Installation

npm i react-native-shimmer-placeholder --save

yarn add react-native-shimmer-placeholder

Usage

Simple

For expo

import { createShimmerPlaceholder } from 'react-native-shimmer-placeholder'
import { LinearGradient } from 'expo-linear-gradient';

const ShimmerPlaceholder = createShimmerPlaceholder(LinearGradient)

<ShimmerPlaceHolder />
<ShimmerPlaceHolder visible={isFetched}>
  <Text>
    Wow, awesome here.
  </Text>
</ShimmerPlaceHolder>

import ShimmerPlaceHolder from 'react-native-shimmer-placeholder'
import { LinearGradient } from 'expo-linear-gradient';


<ShimmerPlaceHolder LinearGradient={Linear} />
<ShimmerPlaceHolder visible={isFetched} LinearGradient={Linear}>
  <Text>
    Wow, awesome here.
  </Text>
</ShimmerPlaceHolder>

For react-native-linear-gradient

import LinearGradient from 'react-native-linear-gradient';
import { createShimmerPlaceholder } from 'react-native-shimmer-placeholder'

const ShimmerPlaceHolder = createShimmerPlaceholder(LinearGradient)

...

<ShimmerPlaceHolder />

import LinearGradient from 'react-native-linear-gradient';
import ShimmerPlaceHolder from 'react-native-shimmer-placeholder'

...

<ShimmerPlaceHolder
  LinearGradient={LinearGradient}
/>
