Using ListView in upperLayer section cancel the drag up action

[icarus31]

Describe the bug I have a column with multiple rows in my upperLayer section. If I leave at it is, I get a "Bottom overflowed" error.

Column(
  children: <Widget>[
    Row(
      children: <Widget> [
      ...
      ]),
    Row(
      children: <Widget> [
      ...
      ]),
  ])

Putting the column within a ListView or similar widget remove the overflow, but now, when dragging up the section, it just scroll the ListView:

ListView(
  children: <Widget> [
    Column(
      children: <Widget>[
        Row(
          children: <Widget> [
          ...
          ]),
        Row(
          children: <Widget> [
          ...
        ]),
      ])
    ])
....

I had the same problem. If you use

new SingleChildScrollView(
        physics: const NeverScrollableScrollPhysics(),
        child: new Column(...),
)   

you can scroll the modal again but not the actual list. So I tried to toggle between NeverScrollableScrollPhysics and null whenever the user hit the top of the list but I was not able to get it to work.

For anyone trying it out, have a look at

• NotificationListener: OverscrollNotification and ScrollEndNotification
• ScrollController: position.pixels and position.userScrollDirection

I'm currently implementing the upper layer scrolling feature for my own project so it will be supported in the next release. Thanks for your interest in the project!

Hi @mcrovero,

I don't want to rush you, by any idea when you think you will release it?

Thanks
