问题描述
需要帮助解决像素溢出问题.
Need help for the Overflowing pixels issue.
我目前正在使用，DefaultTabController-脚手架-建造者-CustomScrollView(SliverList + SliverFillRemaining)
I am currently using a,DefaultTabController-- Scaffold-- Builder-- CustomScrollView (SliverList + SliverFillRemaining)
SliverFillRemaining小部件无法完全滚动，即使当我滚动到极限时，它的高度也仅等于屏幕高度.
SliverFillRemaining widget does not scroll full, it takes height equal to Screen height only, even when i scroll to the extreme.

到目前为止，我已经提到以下内容: https://stackoverflow.com/a/63305024/2975475
试图在SingleChildScrollView-容器-TabBarView内添加TabBarView，但是没有用.
Tried adding TabBarView inside SingleChildScrollView - Container - TabBarView but did not work.
试图在TabView-TabBarView内添加TabBarView，但无效.
Tried adding TabBarView inside ListView - TabBarView but did not work.
删除了TabBarView&每次单击Tab时都会设置setState，但是每次选定的选项卡都会重置为0.
Removed TabBarView & setState on every Tab click, but then the selected tab resets to 0, everytime.
推荐答案
如上面的注释所述，滚动TabBarView内容时，还需要Tabs进行滚动.
As mentioned in the comments above, you also need the Tabs to scroll when the TabBarView content is scrolled.
在这种情况下，我将考虑使用NestedScrollView.检查此处以了解有关 NestedScrollView 的更多信息.
I'll consider using a NestedScrollView in this scenario. Check here to read more about the NestedScrollView.
我以您的代码为例，添加了一个演示如何使用NestedScrollView的演示:
I added a demo of how to use the NestedScrollView using your code as an example:
class ViewEditComplaintDetails extends StatefulWidget {
ViewEditComplaintDetails({Key key}) : super(key: key);
@override
_ViewEditComplaintDetailsState createState() =>
_ViewEditComplaintDetailsState();
}

//UI variables goes below.....
Card _complaintPreviewCard;
//NON-UI variables goes below....
final GlobalKey<ScaffoldState> _scaffoldKey = GlobalKey<ScaffoldState>();
BuildContext _scaffoldContext;
List<Widget> _productRelatedTabs;
@override
void initState() {
super.initState();
_complaintPreviewCard = _getComplaintPreviewCard();
TextStyle _textStyle = TextStyle(fontWeight: FontWeight.w600, fontSize: 12);
var complaintDetailsTab = Text('COMPLAINT\nDETAILS',
textAlign: TextAlign.center, style: _textStyle);
var contactDetailsTab = Text('CONTACT\nDETAILS',
textAlign: TextAlign.center, style: _textStyle);
var typeOfComplaintsTab = Text('TYPES OF\nCOMPLAINT',
textAlign: TextAlign.center, style: _textStyle);
var sampleDetailsTab =
Text('SAMPLE\nDETAILS', textAlign: TextAlign.center, style: _textStyle);
