I believe there are a bunch of questions related to this, but they are all outdated.
I'm looking for a way to render a panorama/360 picture viewer in React Native. So far, all the libraries that try to use Google's VR SDK are outdated or broken, and not usable at all.
I have also tried to use a WebView (with react-360), but web views are just way too slow, doubles RAM usage, and worst of all, can't be used to render 360 pictures stored on the device.
I guess that another option would be to grab an OpenGL library and try to implement it myself, but that's probably a lot of work if there's something made already.
We've recently published the panorama viewer we are using in our apps. Hope it can help you too. #lightbase/react-native-panorama-view

This is a bit of a general question, but perhaps someone can guide me in the right direction.
I'm using a JS library called Vexflow to render music notes. I uploaded some script to my website AND used the same code to build a React Native app.
When comparing both on the same device (Xiaomi A3), the code renders much faster on my website.
Any ideas why?
Cheers,

I have been trying my hands for POC on an idea and trying to find languages which can support Mobile app development (Android/IOS) via single source code.
I zeroed on React-Native and Flutter.
What I found that for React-Native you still have to write code which is platform specific. Components need to be written differently for IOS and Android.
Then I looked in FLutter and I found that - "Flutter's widgets, however, while there are more of them, aren't really adaptive".
I am not able to understand it and what it means.
It would be really helpful if someone can help me with example or guide me to good reference.
In Flutter you have different sets of Widget Collection:
Material Widgets: Android-style
Cupertino Widgets: iOS-style
And lots of Widgets which aren't bound to one of those styles.
With this you are able to create a application looking like any style on any of the available platform. Therefore you can also have iOS-style Widgets on Android and vice versa.
If you want to have iOS Widgets on iOS and Android Widgets on Android, you'll have to create some conditional rendering, which decides wether to render iOS or Android components.
Sidenote: The Material-style Widgets look also really good on iOS. Also you can use a ton of other Widgets to create an UI in your own style.
Does the React Native library "React Native Fast Image" (https://github.com/DylanVann/react-native-fast-image) have any difference in behavior if we use "require()" instead of "{uri:}"?
(I'm confused as "{uri:}" is the only way mentioned in the docs)
They have an issue open which explains how they are planning to go about having local image support, as far as I can tell they have the code merged on master so shouldnt take too long for them to release it.

What's the easiest way to go about indexing a React Native app so that content within the app appears in Spotlight searches?
If you're still interested in indexing your app content using React Native, I've written a plugin to do just that.
As you've figured out, there's no built-in react-native support for this. The only option for you to utilize the Core Spotlight framework capabilities is to create your own native module which will expose this functionality to your react-native code. You can also try to find someone who already wrote this module and made it open source, but I guess you've already tried that.
Since this is the only way, it is also the easiest... That said, it should be pretty easy to implement it yourself, assuming you have some experience with iOS development. If you run into problems you can post your code and I can point you in the right direction if necessary.
I have seen that titanium support CoverFlowView in titanium but it works only on ios, Can anyone have idea to achieve CoverFlow in android with titanium
Thanks in advance
Looks like you are in luck! Someone already built a coverflow module for Android using the Android development environment.
https://github.com/moondroid/CoverFlow
You need to be willing to write the additional code for that to turn it into a module for Titanium.
http://docs.appcelerator.com/titanium/3.0/#!/guide/Android_Module_Development_Guide
It should be possible, but I must admit I've never tried to write one myself.
Basically you cannot get Coverflow on Android. Since it is a native iOs component which is not implemented in Android at all. Frameworks like Titanium always "link" your commands to internal system APIs. When there is no API there is no way to access it. Of course you could try to build it on your own but I think this would not work that well. And its a lot of work!
Additionally cover flow is not really useful (except for holding just a few items). Have a look at my question at ux.stackexchange.
