测试大佬的demo，也会出现类同的情况，希望大佬能指点一下，。情况台下， body: extended.NestedScrollView( headerSliverBuilder: (context, f) { return [ ExtendedSliverAppbar( title: IndexTitle(), leading: Container(), isOpacityFadeWithTitle: false, isOpacityFadeWithToolbar: false, background: IndexBackgroud(), ), SliverPersistentHeader( delegate: BaseSliverPersistentHeader( child: buidTabBar(), maxHeight: 50, minHeight: 50, ), pinned: true, ), ]; }, pinnedHeaderSliverHeightBuilder: () { return pinnedHeaderHeight; }, body: TabBarView( controller: homeController.tabController, children: homeController.pageList, ), ), );

官方的会吗

cqkyis commented 3 years ago

已解决，官方的也有这个问题

zmtzawqlp commented 3 years ago

你可以试着pr ，我看看

cqkyis commented 3 years ago

old那个dart的1032行，if(innerDate <=-1 && innerDart >=1 )解决的，不知道有没有问题

zmtzawqlp commented 3 years ago

有点取巧 而且为啥不写成 innerDate.abs() >=1. 其实之前我也写过，但是不是大于1.0，大于的一个常量，后来merge 官方代码，merge掉了
