PinnableListView

A Flutter ListView widget that allows pinning a ListView child to the top of the list.

Demo

Getting Started

Define the list

  PinController pinController = PinController();

  @override
  Widget build(BuildContext context) {
      return PinnableListView(
          pinController: pinController,
          children: listOfWidgets
      );
  }

Then pin a widget with

  pinController.pin(index)

index meaning the child which you'd like to pin/unpin.

See the example app for more details.

Problems

• Calling setState on PinnableListView after it has changed will crash the list, because it will try to reload the original list.
• Missing implementation for PinnableListView.builder.
• Changing the size of a child after first build will crash the list, as the list calculates widget heights based on the render boxes at the beginning of the app.
