我基本上希望在页面中间有一个TabView导航。 为此,我在NestedScrollView中使用了SliverAppBar。 我的SliverAppBar仅由我的TabView组成,我将TabView包裹在SliverAppBar中,以便使用固定的:真正的礼节。
return Scaffold(
appBar: AppBar(
title: Text('Title'),
),
body: NestedScrollView(
headerSliverBuilder: (BuildContext context, bool boxIsScrolled) {
return <Widget>[
SliverToBoxAdapter(
child: Container(
height: 500,
color: Colors.red,
)),
SliverAppBar(
pinned: true,
bottom: TabBar(
tabs: <Widget>[
Tab(
text: "Home",
icon: Icon(Icons.home),
),
Tab(
text: "Example page",
icon: Icon(Icons.help),
)
],
controller: _tabController,
)),
];
},
body: TabBarView(
children: <Widget>[
PageExample(),
PageExample(),
],
controller: _tabController,
),
),
);
它能解决问题,我的问题是我想隐藏/删除包裹了TabBar的SliverAppBar:
答案 0 :(得分:0)
我需要将expandHeight设置为0:
返回脚手架( appBar:AppBar( 标题:Text('Title'), ), 正文:NestedScrollView(
main.cpp: In function ‘int args_parse_cmd_line(int, char**)’:
<command-line>:0:10: error: ‘FIL’ was not declared in this scope
main.cpp:72:114: note: in expansion of macro ‘MYBRANCH’
%s\n", APPNAME, MAJOR_VERSION, MINOR_VERSION, PATCH_VERSION, BUILD_NUMBER, MYBRANCH);
