I used Highcharts on my project in mobile react native and found after trying to pinch-to-zoom on graph x-axis and y-axis are not refreshing to shows smaller x-coordinate numbers.
However when I used to work in Expo, it was properly worked and showing correct number during pinch-to-zoom.
Please advise if you ran into same issue and how you fixed it? I am guessing there should be an event needs to be trigger to refresh charts.
Tried to use Highcharts zoon feature on react native code for my graph, expecting to see smaller numbers of X and Y axis on graph after pinch-to -zoom
I have found, that you have already asked your question on Freshdesk, our support channel. In the future, please do not duplicate topics across our support channels, as we work as a single team of developers.
The React-Native package is deprecated, so that means, that we dropped support for that package, and it now is in hands of the community. If you need any support with this package, you can create an Issue in GitHub and might find some help there. Alternatively, you can try to search for some new package, which is not official. On the other hand, you can try to use methods, like chart.redraw (https://api.highcharts.com/class-reference/Highcharts.Chart#redraw) or chart.reflow (https://api.highcharts.com/class-reference/Highcharts.Chart#reflow) - they are responsible for redrawing/reflowing the chart, which will refresh the chart.

I am making an app using Compose for Desktop. I am trying to include a simple file download Icon that I know is included in the lengthy set of Material Icons, however it is not available under Icons.Filled. Some of the icons included, in my opinion, are nowhere near as commonly used as download... go figure.
I know that Compose for Android has a dependency for an extended set of Material Icons. I tried adding that dependency to my Desktop app, but it threw errors at me.
For now I have added a Feather Icons set courtesy of DevSrSouza, but I would like to know if there is a way to access the Material Icons extension in Compose for Desktop? Thanks.
I guess you have already found the answer but I also had this problem for long time, so here is a right dependency for compose desktop: "org.jetbrains.compose.material:material-icons-extended-desktop:$compose_version"
The problem
So, I am developing a react native application and I am facing the callenge of selecting multiple images from the user gallery. Just like apps like WhatsApp, Telegram, Twitter and even Reddit do. So with that in mind, i tried to use launchImageLibraryAsync from expo-image-picker but, as specified in their documentation, the "multiple selecion" of images is only supported on the web.
What I have thinked of
So, based on several searches, it seemed like i had to build my own "Gallery". To do this, so far i've tried to use #react-native-community/cameraroll and expo-media-library, but both of them requires that we pass the first property to the getPhotos (for #react-native-community/cameraroll) or to the getAssetsAsync (for expo-media-library) functions, which defines the first items to be fetched. This is a problem because I do not want to fetch like 20 items and then, when the user reaches the end of the list, it fetches more 20 items. I need something like this (this example is from Telegram). You can see that the app never stops me from scrolling, it goes all the way through my entire gallery.
What would also be nice
If you use reddit mobile, you can see that you can also select multiple photos using the several Apps like Google Photos, Files, Google Drive and so on.
This would be even nicer because I wouldn't need to implement a custom made Picker. Do you guys know how could I implement this?
OBS: I am using Expo with Bare Workflow, so I can use just about any package. I also opened a discussion at the Expo repo about it. You can check it here: https://github.com/expo/expo/discussions/15210.
Thank you in advance :)
I have been using this package called expo-images-picker check it out. It has similar function to what you need. It works in Mobile as well.

** anyone who can help me to resolve this. I am tired of this and now this becomes a headache for me. help will be really appreciated. ia m trying on this for one month but invain.**
Take a look at the docs specifically about the attributes maxToRenderPerBatch,updateCellsBatchingPeriod and removeClippedSubviews. In your case, it's rendering 50 items per batch of render, the updateCellsBatchingPeriod maybe is making the list update itself longer than expected and maybe if you set the prop removeClippedSubviews to true the list is going to stay fluid as you want.
I need to show data in graphical representation like stock app in itunes.
There are many libs but I cant find one giving such functionalities.
Can Any body suggest how to implement.
Try using React-native-svg-charts
which you can control size and colors
here is an Example
we working with expo and using mapview, however, there are many restrictions in react native maps, as we are planning to implement turn by turn navigation. Integrating Mapbox would have been the best option, however we do not think it’s best to eject the project as expo doesn’t still support Mapbox. Although, I came across a package, react native maps navigation, I would like to know if anyone has been able to successfully implement it in their project and it functioned properly, and also know if there are any drawbacks that comes along with it. I am asking this because the author says “Please note that this module is usable but still under heavy development. Some properties and/or component names might change without notice.”
Kindly give your suggestions and advice. Thanks
Mapbox works very well in a react-native projects and recommend to use this service for your project but effectively, it don't works with expo so for me, you should eject your project to use it.
I paste here some packages I used for a GPS project (The last one is to get the current position of an user)
react-native-mapbox-gl/maps
mapbox-sdk
react-native-geolocation
Hope that could help you
