kandi X-RAY | react-native-big-list Summary

react-native-big-list is a JavaScript library typically used in Mobile, iOS, React Native applications. react-native-big-list has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a high performance list view for React Native with support for complex layouts using a similar FlatList usage to make easy the replacement. This list implementation for big list rendering on React Native works with a recycler focused on performance and memory usage and so it permits processing thousands items on the list. You can also try it on the published web app: Demo. React Native's FlatList is great but when it comes to big lists it has some flaws because of its item caching. Exists some alternatives like react-native-largelist and recyclerlistview but both have some issues. The react-native-largelist isn't compatible with web and Expo, has native code that sometimes need to be readjusted and maintained, have a weird list item recycles (because it never has blank items), need data restructure and have some issues when trying to process a lot of data (eg: 100,000 items) because it would freeze the CPU. The recyclerlistview is performant but suffers from an empty frame on mount, weird scroll positions when trying to scroll to an element on mount, and the implementation of sticky headers conflicts with Animated. Recycler makes it easy to efficiently display large sets of data. You supply the data and define how each item looks, and the recycler library dynamically creates the elements when they're needed. As the name implies, the recycler recycles those individual elements. When an item scrolls off the screen, the recycler doesn't destroy its view. Instead, the recycler reuses the view for new items that have scrolled onscreen. This reuse vastly improves performance, improving your app's responsiveness and reducing power consumption. When list can't render your items fast enough the non-rendered components will appear as blank space. This library is fully JS native, so it's compatible with all available platforms: Android, iOS, Windows, MacOS, Web and Expo.

Flutter: How do I disable scrolling for a GridView widget, but have scrolling enabled for the page as a whole?

Asked 2022-Feb-06 at 09:48

I'm building an app where I have a page which gives information about a specific trading card. I want the page to be scrollable, but I also want to have a grid on the page, with each grid cell showing one data point. I made the grid using GridView.count().

My problem is that instead of have a page which I can scroll through, the top half of the page stays static, while the grid is scrollable. How do I make the grid static, while the rest of the page scrollable? I intend to have more data below this grid as well, and I want to user to be able to scroll to see all of it, with the grid being a static component of the page.

Here's my code:

You can provide physics: NeverScrollableScrollPhysics() on GridView to disable scroll effect. If you want scrollable as secondary widget use primary: false,

To have Full Page scrollable, you can use body:SingleChildScrollView(..) or better using body:CustomScrollView(..)

ANSWER

Answered 2021-Dec-26 at 14:20

Turns out this error was caused by a popular library I used (settings_ui) that does not work with this version of Flutter (settings_ui: ^1.0.0).

For future readers: Use a later version of this package. There is currently an open issue on github that addresses this.

Update 2022: Dev on settings_ui seems to have gone AWOL and no longer merging PR's the community has forked this project to: https://pub.dev/packages/flutter_settings_ui and here updates are properly merged and a fix has been released in version 1.0.1

For people facing this issue now:

As a monkey patch you can follow the steps in the GitHub issue and edit the package files locally:

In cupertino_settings_item.dart change final ListTileTheme tileTheme = ListTileTheme.of(context); to final tileTheme = ListTileTheme.of(context);

And change _iconColor(ThemeData theme, ListTileTheme tileTheme) to _iconColor(ThemeData theme, ListTileThemeData tileTheme).

Firemonkey Listview & mobile screen orientation in Delphi 11

Asked 2022-Jan-01 at 09:00

I am fairly new to the Firemonkey framework after working with VCL for many years so hopefully this question is not too simple.

I am listing Dynamic Listview Items which I update from a database. I have created the position/layout of the text within the Listview Item using design mode . My question is when I change screen orientation from portrait to landscape do I have to manually change the 'X' position of the text items located within my listview and their width so that the full landscape width of the screen is utilized? There appears to be no anchors for dynamically created Listview items. (The text items just have their generic names for the time being.)

I have a pic below of what I am trying to describe. First pic shows deign mode in portrait and second in landscape.

Any suggestions greatly appreciated.

Portrait mode

The Accessory, Detail and Text items have an Align property that can take values Center, Leading or Trailing. They are recalculated and adjust their position with changes in the screen orientation.

Additionally some items have a separate property, TextAlign, which sets the position for a text within the space of the Align result.

There is no constraint on development language. But,

You need to use same certificates/keys for iOS App
You need to use same key-store/keys for Android App
If you are using local database or file storage, then you should follow the same path in your newly created app as well. If you are using any third-party library to manage the db or file paths, then it may be in different location altogether. (This one actually happened to me. When I migrated my app from a cross-platform framework to Native the database path got changed in release version)
