How do I make my own map on React Native? For example, a map of a shopping center with a floor plan.
Can this be implemented using react-native-maps? Can I make a map in 3D space?
Unless you implement your floor plan as some sort of overlay on a geographical map, react-native-maps may not be the tool for you.
I’ve had success in the past performing this kind of task by creating the floor plan as an SVG and using react-native-svg to render it while also making use of a gesture handler library to make the containing view scrollable/zoomable.

Is there any React native package to create funnel chart like in this?
or how to implement this chart on our own in react-native?
When it comes to drawing lines, shapes, gradients, etc, you have about two decent options in the react-native space.
The first one is React Native Art, the second one is react-native-svg. There are some charting libraries available as well, but when you want full customisation and styling/design options, the best way probably is to stay as close to the drawing api's as possible.
The funnel-graph-js project you mention uses browser SVG to draw the funnel chart, so I guess you can probably copy and adjust some code to achieve a similar result using react-native-svg.
I want to display several components (maybe up to 6) in my React Native app that continuously change their position, i.e. slowly but fluently float on the screen and change their moving direction randomly or based on an angle at which they approach the edge of their parent, if they do. What I don't know is how to change their position dynamically in a performance friendly way. Because I also want to let the user interact with them by tapping on them, it cannot be a video in a background or something similar.
If I were dealing with a standard React app running in a browser, I think I would simply manipulate the element's style attributes top and left. Since I want to implement this in React Native, I think there must be a solution that is way more performant and elegant, involving manipulation of the native elements that back the React Native views or using some animation mechanism, because re-rendering a view with like 6 components at least 30 times per second doesn't seem like an appropriate solution and an overhead in general.
Googling things like "react native dynamically move element" or "react native dynamically change element position" did not bring any obviously appropriate results. I came across a native element method setNativeProps, though, but couldn't find any information on what props I could set to change the element's position on the screen and how performant that would be. I also looked into React Native's Animated API, but could not quite relate my problem to the solutions that this API offers from a first glance.
Does anyone know a mechanism or maybe a library that would be appropriate to use in the situation that I described?
I am Working on react native camera library to taking bitmap.
For example, when we capture a image it return image path, height, width etc.
Instead of these i need bitmap.
The best way to achieve what you're looking to do is likely going to be to use the Native UI Components API for iOS and Android to implement a custom native image view that applies the effects you are looking for.
React Native doesn't give the option of accessing access the raw bitmap data of the React Native (aka. RCTImage) component.
I want to render a three-dimensional cube with images on its six surfaces in React Native, that can be rotated by the user. First, I wanted to use react-native-canvas, but 3D rendering isn't possible within such a canvas.
My second idea was a Web View, that is shown in React Native and that renders the cube. The big disadvantage of this solution is, that a internet connection is necessary. Furthermore, maybe the performance isn't that good this way.
So, do you have any idea how to solve my problem? Thanks for all responds.
I would recommend you use a javascript framework called three.js. it is designed to do exactly what you are looking for.
I have to display above 1000 markers on map. I am using react-native-maps. But the phone becomes unresponsive. Any idea how to display large data on maps?
Marker clustering is what you are looking for.
Unfortunately, react-native-maps doesn't support it, yet. There is an issue and PR though.
Easiest solution for now is to use react-native-map-clustering module on top of react-native-maps
