Make gradient component injectable

[brentvatne]

It would be useful to be able to provide the gradient component similar to how redux-persist asks you to pass in the storage API: https://github.com/rt2zz/redux-persist#v6-upgrade

Good idea. Do you have any plans to create a PR for me?

[brentvatne]

i'm not planning on it but it'd be cool to see :)

another thing that could be done to make this work out of the box in managed expo projects is to do something like this pr react-native-async-storage/async-storage#368 - use .expo.js extension to use expo-linear-gradient rather than react-native-linear-gradient when in expo managed apps

Now we're using :

import { createShimmerPlaceholder } from 'react-native-shimmer-placeholder'

const ShimmerPlaceholder = createShimmerPlaceholder(LinearGradient)
...
<ShimmerPlaceholder />

or

import ShimmerPlaceholder from 'react-native-shimmer-placeholder'

<ShimmerPlaceholder
LinearGradient={LinearGradient}
/>

[brentvatne]

nice one!

For expo user.
No longer imported LinearGradient. It will be added by default

For example

import ShimmerPlaceholder from 'react-native-shimmer-placeholder'
<ShimmerPlaceholder />
