Вы, конечно, можете добавить упомянутый bottomNavigationBar
к SliverAppBar
, используя NestedScrollView
, и добавить bottomNavigationBar
вне его. Вот рабочий код:
return Scaffold(
body: NestedScrollView(
headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
return <Widget>[
SliverAppBar(
expandedHeight: 200.0,
floating: false,
pinned: true,
flexibleSpace: FlexibleSpaceBar(
centerTitle: true,
title: Text("Sliver with bottomnavbar",
style: TextStyle(
color: Colors.white,
fontSize: 16.0,
)),
background: Image.network(
"https://images.pexels.com/photos/396547/pexels-photo-396547.jpeg?auto=compress&cs=tinysrgb&h=350",
fit: BoxFit.cover,
)),
),
];
},
body: Center(
child: Text("Text"),
),
),
bottomNavigationBar: BottomNavigationBar(
type: BottomNavigationBarType.fixed,
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(Icons.home),
title: Text('Home', style: TextStyle(color: Colors.black),),
),
BottomNavigationBarItem(
icon: Icon(Icons.card_giftcard),
title: Text('Deals',style: TextStyle(color: Colors.black),),
),
BottomNavigationBarItem(
icon: Icon(Icons.favorite),
title: Text('Favourites',style: TextStyle(color: Colors.black),),
),
BottomNavigationBarItem(
icon: Icon(Icons.portrait),
title: Text('Profile',style: TextStyle(color: Colors.black),),
),
],
),
);
Надеюсь, что это ответ на ваш вопрос.
