navigation | 前端导航 | Continuous Deployment library

When navigating from Composable A -> Composable B, say Composable A is a Lazy List scrolled halfway down and Composable B is a Lazy List Item Details Screen. Currently, the lazy list scroll position isn't stored, and when navigating back to Composable A from B, the list starts from item index 0. We could store it in a ViewModel, and read the value back, as well as use rememberSaveable, however, I am unsure as to how to implement rememberSaveable so that it scrolls to the saved position after back navigation.

Which method would be preferred to use following good code practices?

Edit: My problem arises from the fact that the listState isn't stored when navigating back from composable B to A. So if we scroll to the bottom and select an item and look at its details, when we navigate back to the list it is scrolled to the top, instead of saving its scrollState.

I'm doing a Group Chat with Firebase and currently I'm using a RecyclerView to display chat messages and I'm having a problem. When you open the app in the fragmented home and you go to chat activity and start chatting (adding elements to recycler view) all goes fine. But, when you go via the NavigationDrawer to another fragment and get back to the chat fragment using again this Navigation Drawer. When you add one element in the chat it appears all in the blank it just displays the last message. Anybody knows why does this happens?

Here I leave the RecyclerView Adapter Code:

I'm using axios in my app. When I make a post request for the very first time after opening the app, it is failing with the following error. From second time onwards, it works without any issue.

For a project for my study I am working on a React Native project, but I am stuck. I want to give the prop 'Score' to Card.js and based on that score a color has to be defined; 'transparancyColor'. Currently, the props are passed from Home.js to Card.js and the transparencyColor is defined there. Is this a smart way, or do I have to do this at Home.js? And how?

The code of Card.js looks as follows:

I have an Activity. In the Activity, I have a Navigation Drawer on the Left and a fragment. In the Navigation Drawer, I have a textview for Name. I want to set the text view from Fragment to Navigation Drawer in activity

I'm developing a simple navigator with mapbox API for Android. I'm creating some routes using https://docs.mapbox.com/playground/directions/ playground and i would like to use the generated JSON to generate a DirectionsRoute object. So i call DirectionsRoute.fromJson() but when i do it, the application crashes with this error:

I have a navbar and sidebar component in my nextjs app. In my index component I'm using useState to show and hide sidebar on mobile device.
It works perfectly fine but I want to add animation when user clicks on hamburger menu, the sidebar should be animated left to right and when clicked on close icon it should go back to right to left. FYI I am using tailwind css.

Here's the code:

Hello guys so I'm trying to make Splash Screen with Stack Navigator. So I Have 3 Main Files App.js , Home.js, and SplashScreenJs. I want my Splashscreen to move into Home after 5 seconds but I can't afford to make it. I was able to use console log with the UseEffect but not with the navigate.

I'm trying to use react-native navigation. I installed the app, everything went alright. Now I'm having this problem with Expo when I try and create a navigation in both ios and web:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of ExpoRoot.
