NeverScrollableScrollPhysics doesn't work for Scrollable inside DraggableScrollableSheet in 3.7.3

Steps to Reproduce

For Android:

Execute flutter run on the code sample
Try to scroll the list.
On 3.3.10 it will NOT scroll, on 3.7.3 it will scroll.

Expected results:
Expected it to not be movable by scrolling gestures as in previous version of Flutter.

Actual results:
It actually scrolls, which may break UI/UX in certain cases (when the app expects the sheet to be scrolled via controller).

For Web:

Seems like on web it works correctly.

Code sample

import 'package:flutter/material.dart';

void main() {
  runApp(App());
}

class App extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Stack(
          children: [
            DraggableScrollableSheet(
              maxChildSize: 1,
              builder: (context, scrollController) => SingleChildScrollView(
                physics: const NeverScrollableScrollPhysics(),
                controller: scrollController,
                child: Column(
                  children: List.generate(
                    200,
                        (index) => Text(index.toString()),
                  ),
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }
}

Triage report

I can reproduce this issue with Master (3.8.0-14.0.pre.2) and Stable (3.7.3). I can also confirm that it doesn't scroll in 3.3.10

Code Sample (Same as OP)

import 'package:flutter/material.dart';

void main() {
  runApp(const App());
}

class App extends StatelessWidget {
  const App({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Stack(
          children: [
            DraggableScrollableSheet(
              maxChildSize: 1,
              builder: (context, scrollController) => SingleChildScrollView(
                physics: const NeverScrollableScrollPhysics(),
                controller: scrollController,
                child: Column(
                  children: List.generate(
                    200,
                    (index) => Text(index.toString()),
                  ),

            ),
          ],
        ),
      ),
    );
  }
}

@xu-baolin

@xu-baolin could you please estimate when this will be fixed? I have an app with the complex UI behavior which relies on the fact that the DraggableScrollableSheet can't be scrolled with gestures, and I can't release it without that fix.
