I'm looking for a method in React Native in which I can move an object by simply listening to the events KEY_DOWN, KEY_UP and KEY_MOVE. And as I move my finger on the component (KEY_MOVE), the position of the component moves along the X axis as per the new X axis I have. In Android (Java), I just did that part by doing this.setX(motionEvent.getX())
Since I'm migrating from Native Android to React Native, I'm having a little trouble making this work. Any help is appreciated.
You can use the PanResponder to get the touch events and then you can use the Animated API to get do the animations to move the view.
See https://moduscreate.com/animated_drag_and_drop_with_react_native/ for a full example.

I want to render a Bubble Chart (Circle Packing) dynamic with an data array as a prop in React Native using EXPO (no native code). I wonder which way I could go to implement this chart. Do I use d3? And if yes, does it work for React Native? Are there other ideas on how to implement this bubble chart? Does it work only with SVG? Or d3 including SVG?
I found also a react library that renders the Bubble Chart like in the picture below but the styles and other attributes from react aren't matching to React Native.
I have not yet found an answer to this problem. Does anyone in the community encounter this problem and solved it?
You can use react-native-chart-wrapper as it is providing bubble chart with a list of additional charts
We're trying to find out if a 360 3D image rotation package for React Native exists for both Android and iOS. (or if it's straight forward without)
e.g. http://www.voidcanvas.com/demo/28823deye/ (thats just a jQuery example)
We're aware that there's things like React 360, and Google VR - however these put YOU in the center of the 360 environment, rather than putting an image sequence in the center - and letting you rotate the object.
currently react native doesn't have such things but you can use webview inside react native and use a javascript library to achive that. or you can implement yours with react native gesture handler
The Yelp app for iOS is designed such that after you enter and send a search query, something like this comes up:
The screen consists of a map control in the background, with a screen on top displaying a list view that you can swipe up/down depending on whether you want to see the list/map (respectively).
How would something like this be accomplished using React Native? For example, would the React Navigation or React Native Swiper libraries help me superimpose a list view on top of the map control?
You can use PanResponder.

You could use Lottie: http://airbnb.io/lottie/
You would have to make the animation outside and then use it as a view with absolute position but it should work. That way you could control the flow.
Also, you could expose that native code in RN as a Native Module.
