Scrolling not working with SingleChildScrollView

Question

I want to do scrolling using flutter driver on a page that uses SingleChildScrollView.. the layout looks like this

return Scaffold(
 backgroundColor: PinColorsV2.neutralMin,
 body: NotificationListener<OverscrollIndicatorNotification>(
 onNotification: (overscroll) {
 overscroll.disallowGlow();
 return true;
 },
 child: LayoutBuilder(
 builder: (context, constraints) {
 return SingleChildScrollView(
 key: Key(ProfileSettingKey.profileScrollView),
 child: ConstrainedBox(
 constraints: BoxConstraints(
 minWidth: constraints.maxWidth,
 minHeight: constraints.maxHeight,
 ),
 child: IntrinsicHeight(
 child: Column(
 mainAxisSize: MainAxisSize.max,
 children: <Widget>[
 BusinessCardProfileWidget(),
 Expanded(
 child: Padding(
 padding: EdgeInsets.only(top: 10.0),
 child: ProfileSettingsWidget(),
 ),
 ),
 ],
 ),
 ),
 ),
 );
 },
 ),
 ),
 );

and here's how i scroll in my flutter driver script:

await world.driver.scrollUntilVisible(ProfileSettingFinder.profileScrollView, ProfileSettingFinder.logout, dyScroll: -15000.0, timeout: scrollTimeoout);

the page actually scrolls, but it only scrolls once a little bit.. not until my widget that i search for is displayed..as far as i know scrollUntilVisible command should keep scrolling until my desired widget shown

i noticed that the behavior is different when the layout is using ListView.Builder.. this is on different page on the app

return ListView.builder(
 key: Key(HomeKey.homeListView),
 itemCount: 1,
 itemBuilder: (context, index) {
 return Column(
 children: <Widget>[
 _staticBanner(context, model),
 if (_remoteConfigService.agentDashboardEnabled) ...[
 UIHelper.vertSpace(12),
 AgentDashboardWidget(),
 ],
 if (_remoteConfigService.howToGetCommissionEnabled) ...[
 UIHelper.vertSpace(20),
 HowToGetCommissionWidget(),
 ],
 if (_remoteConfigService.featureToggles.infoForYouSectionEnabled) ...[
 InfoForYouWidget(),
 ],
 if (_remoteConfigService.projectFilterShortcutEnabled) ...[
 UIHelper.vertSpace(24),
 BuildingTypeFilterWidget(),
 ],
 if (_remoteConfigService.userSellingPointEnabled) ...[
 UIHelper.vertSpace(36),
 UserSellingPointWidget(
 onTapCallback: () => _goToBenefitWithPinhomeView(context, model),
 ),
 ],
 if (_remoteConfigService.featuredProjectEnabled) ...[
 UIHelper.vertSpace(28),
 ProjectHorizontalListWidget(
 type: ProjectHorizontalListType.featuredProjects,
 ),
 ],
 if (_remoteConfigService.newProjectEnabled) ...[
 UIHelper.vertSpace(28),
 ProjectHorizontalListWidget(
 type: ProjectHorizontalListType.latestProjects,
 widgetKey: Key(HomeKey.proyekTerbaruHeader)
 ),
 ],
 UIHelper.vertSpace(12),
 ],
 );
 },
 );

i can scroll on that ListView normally, until my desired widget found, using the exact same syntax.. something like

await world.driver.scrollUntilVisible(HomeFinder.homeListView, HomeFinder.proyekTerbaruHeader, dyScroll: -500.0, timeout: temot);

so do i have to use different command if i want to scroll on a layout that uses SingleChildScrollView?

Incase anyone stumbles upon this, with the new integration_test package this works:

await tester.scrollUntilVisible(myFinder, 20,
 scrollable: find.descendant(of: find.byType(SingleChildScrollView), matching: find.byType(Scrollable)));
