how to display application in flat list in react native - react-native

How can I display a list of installed applications in React Native and show their respective icons along with their names?
How to display a list of installed applications in React Native, including:
Retrieving the list of installed applications
Displaying the names and icons of the applications
Implementing the display using the best practices and efficient methodologies in React Native.

I would probably use this library: https://www.npmjs.com/package/react-native-installed-application
Initialize the library, get list of apps and persist it in some form of state.
Create a component with a list that uses the previous saved state to render the elements.

Can we use Kendo-React UI in React-Native?

I want to use Kendo UI React with my React Native application but I got some problems with the getting started.
I followed every step inside https://www.telerik.com/kendo-react-ui/getting-started/ but I encounter this error : "Invariant Violation: View config not found for name button"
So is there a way to use it in my react native mobile application ?
Kendo React can´t be implemented in React native at the moment. Telerik is considering since August last year to implement it according to market demand.

You should consider a different UI library or stack for your project.
Nativescript can be a valid option depending on your needs.

How can I do Signature Capture in React Native?

I'm trying to understand how I can do a signature capture in React Native. My App is created with create-react-native-app and Expo and I'd prefer to not have to eject the app to get this functionality to work.
Would it be possible to wrap something like this in a webview? https://github.com/szimek/signature_pad
I've also looked at this project, https://github.com/RepairShopr/react-native-signature-capture but it requires me to eject the app and use react-native link.
Looking for any advice or suggestions on how to implement this feature while keeping my project as straightforward as possible (ideally, using create-react-native-app, but if this isn't possible could someone please explain to me why?)
The way React Native works is that each component available in React Native maps to a native component in the underlying platform.
ie. a <Image /> is an ImageView in Android and a UIImageView.h in iOS.
The Javascript code itself runs in a Javascript thread on each platform and as you use Components in React Native, there's a translation layer that passes information from JS into the React Native bridge that then results in corresponding native components being created.
By default, React Native has included the following components: https://facebook.github.io/react-native/docs/components-and-apis.html#basic-components which means that only those components come out-of-the-box in React Native. If you want other components, then you have 2 options, either create a "composite" component in which your JS component is written into other JS components or, if your feature needs a native component not yet exposed by React Native, write your own "native" component to expose certain native functionality to your React Native code.
The way Expo works is that they have wrapped React Native and a handful of 3rd party components and built it within their application. The reason why you can't use a 3rd party native component they don't support is because when that component is used, the app itself doesn't have translation code to go from JS to a native Android/iOS view.
So, to do what you're asking, you'd need to find either a "native" drawing component that Expo has included in their platform/app. OR you need to find a "composite" drawing component that is built with other default React Native components (or other components Expo supports).
ie. On Android, I might build this with a Canvas view, but from what I can tell React Native doesn't support that object natively, so I would probably write this myself, etc.
It's hard for Expo to support every 3rd party "native" component out there because React Native is open source and it iterates so fast that most community-built components aren't always up to date or they might conflict with one another.
I am using react-native-signature-capture.
Working properly on both Android and iOS.
I know it's been a while, but there is an interesting article here: https://blog.expo.io/drawing-signatures-with-expo-25d1629ca1ac
Wait, but how?
Using “expo-pixi”, you can add a component that lets you choose your brush’s color, thickness, and opacity. Then when your user lifts her finger, you get a callback. From there you can take a screenshot of the transparent view or get the raw point data if that’s what you’re looking for.

Initialize React Native portion of hybrid app with structured data

Problem
I'm integrating React Native into an existing Android app (ie. making a hybrid app). I've created an Activity to host a React Native view. This works fine.
Now, I need to pass structured data from native into React Native. Represented as JSON, it looks something like this:
{
"landscape": ["http://example.com/1.jpg", "http://example.com/2.jpg"],
"portrait": ["http://example.com/3.jpg", "http://example.com/4.jpg"]
}
Given the context I describe how can I make this data available as props inside of the React Native app?
I see that this is an initialProperties argument available, but it seems to accept a Bundle, which as far as I can tell (Android newbie here) only accepts scalar values.
One option I am considering
Create JSON object in Java
Convert to a string
Add to Bundle and pass into initialProperties
Ingest as JSON and deserialize in React Native app
... but this seems hackish and requires me to add special code for Android that was not required for iOS.
Alternatives?
Is there a straightforward approach that I am missing?
Have you tried passing an array of strings into the Bundle?
bundle.putStringArray("landscape",yourArrayOfStrings]);

Google Places Web Api

I am working on a project to create a Uber clone. I will need to have a text input which will list predicted addresses like in the actual Uber app when user types in the text input. Once user selects the location, a map will be automatically updated.
Can I achieve this using the Google places web api alone, without touching native code? I know this can be achieved using react native google places (which needs to touch native code) but I am not comfortable toying with native codes.
If possible to achieve using Google places web api, anyone can share samples of how this is done? Tutorials online only show how to set markers for certain types only eg hotels which is not what I want to achieve. I m not sure what is the 'type' I should set when using Google places web api.
I use react native init to initialize my react native app
Thanks
