QUESTION
I would like to have a ListView in flutter which provides lazy loading in both directions (up, down).
Example:
- There are 60000 items in the backend database which can be theoretically displayed.
- First I want to display the items 100..120
- From these indices I want to be able to scroll up and down while lazy loading the new items
Things to consider:
- The top and bottom edge (current index < 0 or > 60000) should be bouncing if reached while scrolling
What I've tried:
- Most of the approaches in Flutter ListView lazy loading. These solutions just worked for lazy loading in one direction (e.g. down or up if list is reversed). If scrolling into the other direction, the list view "jumped" because indices changed (the old index 1 isn't the new index 1 anymore).
- ScrollablePositionedList (https://pub.dev/documentation/flutter_widgets/latest/flutter_widgets/ScrollablePositionedList-class.html): Here the issue was that the widget wants to load every item if e.g. an itemcount of 60000 is given. Anyhow, the itemcount is required in order that this solution works properly.
- IndexedListView (https://pub.dev/packages/indexed_list_view): Same issue as in ScrollablePositionedList. Anyhow, here also the "bouncing" at the top and bottom of the list didn't work (because of missing scroll extents).
- InfiniteListView (https://github.com/fluttercommunity/flutter_infinite_listview): Same issue as in IndexedListView
I hope that here are some pretty smart people who can help me solving this issue ;). I'm already searching and trying around since days on this issue. Thanks!
Update To make things clearer: Here is an example for a ListView with lazy loading for scrolling up and down (Most of the code copied from https://stackoverflow.com/a/49509349/10905712 by Rémi Rousselet):

I just created a new library bidirectional_listview which can be used to solve this issue. BidirectionalListView is a fork from infinite_listview.
Old Answer
I just solved it by adapting the library InfiniteListView a bit. I had to extend a setter for minScrollExtent and maxScrollExtent. In addition, I added a separate count for negative indices:
QUESTION
I have my widgets setup in the following hierarchy to pass data between the two tabs

Answered 2019-Jun-20 at 01:26You call listen on the Stream every time _InfiniteScrollListViewState.build is called. That will result in your callback being invoked multiple times. You should listen to the Stream only once.
You also perhaps should consider using a StreamBuilder widget instead.
QUESTION
I've got a Flutter app with 2 tabs: one that manages and receives a continuous flow of data, the other tab displays the data as it comes in.
How do I pass the data from the first tab to the second? Most of the post I see are about passing data between parent and child, not child to child.
Would I use GlobalKey? is there a better option?
This is the main build function:
...ANSWER
Answered 2019-Jun-18 at 22:42In this case, it is recommended to use InheritedWidget.
The documentation for InheritedWidget is very comprehensive, including a video from the Flutter team.
First of all, you probably want to create a class that holds the data you want to share.
