Bloc: refresh part of screen can be done with Bloc?

[MahdiPishguy]

i have a simple question. how can i refresh part of screen with bloc? for example you suppose we have weather sample as you put in github,

in that we suppose we have a listview below of city name, and thats get some other cities list to show temperatures. when we scrolling down and we want to reload again this list, can be doable with Bloc pattern?

i guess i can introduce StateRebuild pattern which we can refresh simple part of our UI

You should use BlocBuilder's as deeply as possible in your widget tree as well as utilize it's condition parameter. In your example you would probably have a single bloc where you would handle all cities. ListView would handle lazy loading of items from your bloc state.

Hi @MahdiPishguy 👋
Thanks for opening an issue!

As @RollyPeres mentioned you can just wrap the part of your ui that you want to change in BlocBuilder and add a condition to optionally have more control over how often it rebuilds. You can check out the timer tutorial for an example.

Hope that helps! 👍

@MahdiPishguy can you share a sample app or something concrete that you’re having issues with? It’s hard to help without having any context.
