Hello,

Create a custom widget to be able to \"scroll to\" is for my part an uncomfortable solution... we loose the nocode spirit logic of FF...

I hope FF team would add scrollTo position functionnality soon ! But until this time, after some tries (some weeks searching and tries 😃 I'm stubborn), I have finally found a way to use the scroll to position without creating a custom widget.
This solution has to be tested . So please tell me if you use it, if it is suitable and works fine.

SOLUTION without custom widget to scroll To index in a listView with fixed height items:

Logic : Some appState variables and 2 simple custom action would do the job. I'm using the brilliant logic used by a community member in THIS POST for another subject of socket... the trick is that JSON variable are dynamic one's and can be any type...

Here the demo :

And you can test in LIVE the project HERE.

prerequisites : listView must be fixed height items and you have to convert your item widget to a component as we need the \"on Initialization\" event of component to get the scroll listView controller.

create appState \"appMyListViewController\" as JSON not persistent : we would save the listView controller in this
create appState \"appMyListViewControllerReset\" as boolean not persistent
create appState \"appListViewItemHeight\" as double not persistent : it will save the item size of the listView (indeed this size seems to not be exactly the same between plateform.. in case of...)

create a \"appMyListViewControllerSet\" custom action with \"Include BuildContext' checked (see on the right in action settings) :

code :

bool appMyListViewControllerSet(BuildContext context) {\n  if (!context.mounted) {\n    print('context not mounted');\n    return false;\n  }\n\n  /* get ancestor listView controller */\n  // using JSON appSate tips found in see https://community.flutterflow.io/ask-the-community/post/global-variable-which-stores-an-object-Bpf2S6lNLKlFzyA\n  // in fact JSON is dynamic = any type...\n  if (FFAppState().appMyListViewController == null ||\n      FFAppState().appMyListViewControllerReset) {\n    ListView? listView = context.findAncestorWidgetOfExactType<ListView>();\n    FFAppState().appMyListViewController = listView?.controller;\n    FFAppState().appMyListViewControllerReset = false;\n\n    FFAppState().appListViewItemHeight = context.size!.height;\n  }\n  return true;\n}

create the \"myScrollToIndex\" custom action :

code :

Future myScrollToIndex(int index) async {\n  if (FFAppState().appMyListViewController == null) return false;\n\n  double offset = 0;\n  if (index > 1) {\n    offset = index * FFAppState().appListViewItemHeight;\n  }\n\n  FFAppState().appMyListViewControllerReset = true;\n  await FFAppState().appMyListViewController.animateTo(\n        offset,\n        duration: Duration(milliseconds: 100),\n        curve: Curves.ease,\n      );\n\n  return;\n}

add the \"appMyListViewControllerSet\" custom action to the \"On Initialization\" event of your listview item's component
then add the \"myScrollToIndex\" custom action to your choosen button passing target index parameter
you have to create at least one standard FF scrollTo begin or end to listview to activate standard controller on the listview in FF generated code, else no controller will be generate and usable:

That's it ! 🎉

Hope it helps. tell me!
If some expert can help to improve code, you're welcome.

This solution should be improve for listView with variable height items... for my part, I need this for one of my project...
I hope we could fix it. :😉 keep in touch !
