[英]How to make a floating search bar on top of Google Maps in Flutter?
我正在尝试在我的地图顶部制作一个浮动搜索栏,就像谷歌地图应用程序中的搜索栏一样。 像这样的东西——
我似乎无法让它漂浮。 搜索栏不会覆盖在地图上。 它只是在自己的框中呈现。
void main() {
runApp(MaterialApp(
title: 'Navigation Basics',
theme: ThemeData.dark(),
home: MyAppState(),
));
}
class MyAppState extends StatelessWidget {
final LatLng _center = const LatLng(28.535517, 77.391029);
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: FloatAppBar(),
body: Map(_center),
floatingActionButton: FloatingActionButton(
onPressed: () {
Navigator.push(
context,
MaterialPageRoute(builder: (context) => Report()),
);
},
child: Icon(Icons.add, semanticLabel: 'Action'),
backgroundColor: Colors.black87,
),
floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
bottomNavigationBar: BottomNavBar(),
),
);
}
}
class FloatAppBar extends StatelessWidget with PreferredSizeWidget {
@override
Widget build(BuildContext context) {
return (FloatingSearchBar(
trailing: CircleAvatar(
child: Text("RD"),
),
drawer: Drawer(
child: Container(),
),
onChanged: (String value) {},
onTap: () {},
decoration: InputDecoration.collapsed(
hintText: "Search...",
),
children: [
],
));
}
@override
Size get preferredSize => Size.fromHeight(kToolbarHeight);
}
我希望搜索栏浮动在地图顶部,但它呈现在自己的框中。
Stack(
children: <Widget>[
// Replace this container with your Map widget
Container(
color: Colors.black,
),
Positioned(
top: 10,
right: 15,
left: 15,
child: Container(
color: Colors.white,
child: Row(
children: <Widget>[
IconButton(
splashColor: Colors.grey,
icon: Icon(Icons.menu),
onPressed: () {},
),
Expanded(
child: TextField(
cursorColor: Colors.black,
keyboardType: TextInputType.text,
textInputAction: TextInputAction.go,
decoration: InputDecoration(
border: InputBorder.none,
contentPadding:
EdgeInsets.symmetric(horizontal: 15),
hintText: "Search..."),
),
),
Padding(
padding: const EdgeInsets.only(right: 8.0),
child: CircleAvatar(
backgroundColor: Colors.deepPurple,
child: Text('RD'),
),
),
],
),
),
),
],
),
更新
我觉得现在这样会更适合你=> FloatingSearchBar通过罗迪Darvis:“)
