NestedScrollView + SliverAppBar isn't work when SingleChildScrollView with controller is child.

The following code is an example:
class TestScrollablePage extends StatefulWidget {
  @override
  _TestScrollablePageState createState() => _TestScrollablePageState();
}

class _TestScrollablePageState extends State<TestScrollablePage> {
  final controller = ScrollController();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        child: NestedScrollView(
          headerSliverBuilder: (context, innerBoxIsScrolled) {
            return <Widget>[
              SliverAppBar(
                expandedHeight: 121,
                pinned: true,
                flexibleSpace: Container(
                  color: Colors.red,
                ),
              )
            ];
          },
          body: Container(
            child: SingleChildScrollView(
              controller: controller,
              child: Column(
                children: <Widget>[
                  Container(
                    color: Colors.yellow,
                    height: 400,
                  ),
                  Container(
                    color: Colors.green,
                    height: 400,
                  ),
                  Container(
                    color: Colors.pink,
                    height: 400,
                  ),
                ],
              ),
            ),
          ),
        ),
      ),
    );
  }
}

When I add a controller on SingleChildScrollView, SliverAppBar can't be folded. But when I remove the controller, it can work. Is this situation normal?

Hi @JoeCiou
try setting a hight for the Container that holds the SingleChildScrollView

sample
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) => MaterialApp(
    home: MyHomePage(),
  );
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  final ScrollController _controller = ScrollController();

  @override
  Widget build(BuildContext context) => Scaffold(
    body: NestedScrollView(
      headerSliverBuilder: (context, innerBoxIsScrolled) =>  <Widget>[
        SliverAppBar(
          expandedHeight: 100,
          pinned: true,
          flexibleSpace: Container(
            color: Colors.red,
          ),
        )
      ],
      body: Container(
        height: 100, // <= need a fixed height
        child: SingleChildScrollView(
          controller: _controller,
          child: Column(
            children: <Widget>[
              Container(
                color: Colors.yellow,
                height: 400,
              ),
              Container(
                color: Colors.green,
                height: 400,
              ),
              Container(
                color: Colors.pink,
                height: 400,
              ),
            ],
          ),
        ),
      ),
    ),
  );
}

Please see https://flutter.dev/community for resources and asking questions like this,
you may also get some help if you post it on Stack Overflow.
Closing, as this isn't an issue with Flutter itself,
if you disagree please write in the comments and I will reopen it
Thank you

The solution isn't working for me.
I don't know idea if it is an issue with Flutter itself.
May it reopens or I need to post on Stack Overflow?
Thank you for your reply.

Hi @JoeCiou
could you please try the code I provided
with flutter run --verbose
and provide the logs
Thank you

Sure, the isn't whole log because it is too long:

HI @JoeCiou
could you please attach the full log as .txt
thank you

@iapicca Sorry, I am late.
The log file for you:
log.txt

Hi @JoeCiou
your logs are clean I'm not sure what kind of behaviour you are experiencing
running this code (same as above)
can you please describe what doesn't work specifically
Thank you

Hi @iapicca
You can check the video that I run the code on my side.
DartPad Video
Simulator Video
They have some differences but I think they aren't expected results.
Thank you

Hi @JoeCiou it looks like in your reproduction that you are providing your own scroll controller to the inner scroll view. This will not work with a NestedScrollView.  This is because the NestedScrollView creates and coordinates the scroll controllers on the inner and outer scroll views to keep them in sync and aligned correctly. See #11271.
Notice if you scroll the header directly, it will collapse and open, while the body scrolls independently. They have been disconnected by overriding the scroll controller. If you need to access these inner and outer controllers, the NestedScrollView.State documentation has an example.
I think this is working as intended so I am going to close it. Let us know if this hasn't been resolved and we can certainly re-open. :)
