React-native-slider: Implement thumbImage for Android

[akrger]

Describe the Feature

The thumbImage should work on both platforms, ideally by not changing the current API.

Possible Implementations

I tried to supply a ReadableArray as a prop, but failed to do so (require('assetsource') returns a double - how can one get the image data from that?).

Is there another library that can do this?

Edit: react-native-multi-slider seems to offer more options, flexibility and styling options (crossplatform).

[akrger]

Yes, but it is using deprecated React lifecycle functions (componentWillReceiveProps). It would also be nice to have the thumb image support in the official React Native slider package, to not be dependent on another package.

[Dror-Bar]

Yes it uses some deprecated functions, and yet it seems that it is a superior library due to it's greatly enhanced control over the component.

I opened a pull request. https://github.com/react-native-community/react-native-slider/pull/106
