QUESTION
I'm currently learning and converting my code to BLoc pattern. Before I'm using flutter_pagewise ^1.2.3 for my infinite scroll using Future<>
but I don't know how to use it using bloc or is it compatible with it.
So now I'm trying infinite_scroll_pagination: ^2.3.0 since it says in its docs that it supports Bloc. But I don't understand the example code in the docs for bloc. Can you give me a simple example of how to use it with bloc? I'm currently using flutter_bloc: ^6.1.3.
Here are my bloc script:

QUESTION
I'm learning Flutter and there is something I cannot grasp my head around.
I implemented a Infinite scroll pagination, with a package (infine_scroll_pagination
),
it works fine, but the data this Package
is getting, comes from a Future
call, which takes data from the WEB
, and parses it in my Provider Class
.
My issue is, the data
that is loaded by the Infinite Scroll widget
, cannot be accessed, in its state
, anywhere else.
Example:
Let's take a contact list
, that loads 10 contacts at a time:

Answered 2021-Mar-12 at 16:47EDIT : I removed the original answer to give a better sample of what the OP wants to achieve.
I made a repo on GitHub to try to show you what you want to achieve: https://github.com/Kobatsu/stackoverflow_66578191
There are a few confusing things in your code :
- When to create instances of your objects (ContactsService, Contacts)
- Provider usage
- (Accessing the list of the pagingController ?)
- Parsing a JSON / using a factory method
The repository results in the following :
When you update the list (by scrolling down), the yellow container is updated with the number of contacts and the number of favorites. If you click on a Contact, it becomes a favorite and the yellow container is also updated.
I commented the repository to explain you each part.
Note: the Contacts class in your code became ContactProvider in mine.
The ContactsService class to make the API call :
QUESTION
I'm using Parchment to add menu items at the top. The hierarchy of the main view is the following:
NavigationView -> TabView --> Parchment PagingView ---> NavigationLink(ChildView)
All works well going to the child view and then back again repeatedly. The issue happens when I go to ChildView, then go to the background/Home Screen then re-open. If I click back and then go to the child again the back button and the whole navigation bar disappears.
Here's code to replicate:
...ANSWER
Answered 2021-Mar-04 at 10:29Okay I found the issue while debugging something else that was related to Parchment as well.
The issue is updateUIViewController()
gets called each time the encompassing SwiftUI state changes (and when coming back to the foreground), and the PageController
wrapper provided by the library will call reloadData()
since the data source data has already been set. So to resolve this just remove/comment out the reloadData()
call since the PageController will be re-built if the relevant state changes. The same issue was the cause for the bug I was debugging.
QUESTION
I want to edit the ascx file for the pagingcontrol because it appears like this:
Notice the "Page 1 of 4" and the "First..." sticks together, and it is really annoying to look at. But when i tried to look for the pagingcontrol file to try to edit it, I cannot find it anywhere.
I read somewhere that there is supposed to be a pagingcontrols file in the controls folder but it is not there for me.
How can i edit the pagingcontrol file?
Thanks.

Answered 2020-Jun-26 at 00:49I would recommend using CsS to style this. Changes to the default controls is a breaking change and would be lost with an upgrade.
QUESTION
I hava a UIPageViewController
that holds an array of ContentUIViewController
, these have scrollviews in them.
When the scrollview scrolls I want to recognise this in the view controller that is the parent of the UIPageViewController
(added as child)
What would be the best route to achieve this? as currently I tried delegating the didScroll
back to the viewmodel for the ContentUIViewController
then feeding that into the parent of the UIPageViewController
to adjust header height that I want to collapse, but it doesn't work well / is very hacky
Is there a way to read delegate output in the a child vc to the parent vc without feeding it back through viewmodels? This is proving tricky due to the array nature of the UIPageViewController
rather than a single child VC.
Updated:
...ANSWER
Answered 2019-Jun-28 at 11:37Here is how you can get that working.
1. Create a handler
in ContentUIViewController
that will be called in scrollViewDidScroll(_:)
method for each contentOffset
change.

ANSWER
Answered 2018-Nov-12 at 04:33The issue you described above has already been fixed. In addition, even if it's is not fixed, you could walk around it by [FromQuery(Name="xxx")]
. See dougbu's walkaround.
It seems that you're using the [ApiController]
, I test it with 2.1.302
and 2.1.402
, it works flawlessly.
Let's say you want to query against MyColoumnFilter
, which will be used as your T ColumnFilters
