当header的高度已经超过屏幕高度了，body还使用SliverFillRemain的话，会导致屏幕越界报错

需要增加一个参数：bodyIsFillRemaining来决定是否使用_ExtendedSliverFillRemainingWithScrollable

List _buildSlivers(BuildContext context,
ScrollController innerController, bool bodyIsScrolled) {
return [
...headerSliverBuilder(context, bodyIsScrolled),
bodyIsFillRemaining ? _ExtendedSliverFillRemainingWithScrollable(
child: PrimaryScrollController(
automaticallyInheritForPlatforms: TargetPlatform.values.toSet(),
controller: innerController,
child: body,
),
) : SliverToBoxAdapter(
child: PrimaryScrollController(
automaticallyInheritForPlatforms: TargetPlatform.values.toSet(),
controller: innerController,
child: body,
),
),
];
}

无所谓的。release 没影响。因为可以滚动，也不会真正溢出
