Reduce space between Tabbar and Listtile - flutter

I want to reduce the space between Tabbar and listtile. I wrote them in two different files so i'll add both the codes. tried adding padding but no use.
main.dart
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
themeMode: ThemeMode.system,
home: DefaultTabController(
length: 4,
child: NestedScrollView(
headerSliverBuilder: (context, innerBoxIsScrolled) => [
SliverAppBar(
pinned: true,
floating: true,
systemOverlayStyle: SystemUiOverlayStyle.dark,
title: const Text(
"WhatsApp",
style: TextStyle(letterSpacing: 1.0),
),
backgroundColor: colour,
actions: [
MaterialButton(
minWidth: 1.0,
onPressed: () {},
child: const Icon(
Icons.search,
color: Colors.white,
)),
MaterialButton(
minWidth: 1.0,
onPressed: () {},
child: const Icon(
Icons.more_vert,
color: Colors.white,
))
],
bottom: const TabBar(
dragStartBehavior: DragStartBehavior.start,
indicatorColor: Colors.white,
tabs: [
Tab(
iconMargin: EdgeInsets.only(left: 1.0, right: 1.0),
icon: Icon(Icons.photo_camera),
),
Tab(child: Text("CHATS")),
Tab(child: Text("STATUS")),
Tab(child: Text("CALLS"))
]))
],
body: const TabBarView(
dragStartBehavior: DragStartBehavior.start,
children: [Camera(), Chats(), Status(), Calls()]),
),
));
}
}
chats.dart
class _ChatsState extends State<Chats> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Padding(
padding: const EdgeInsets.only(top: 1.0),
child: ListView.separated(
itemBuilder: (context, index) => ListTile(
title: Text("Person $index"),
subtitle: Text("your message is this"),
trailing: Text("$hr:$mi $ti"),
leading: MaterialButton(
padding: EdgeInsets.all(1.0),
height: 1.0,
minWidth: 1.0,
elevation: 0,
onPressed: () {},
shape: CircleBorder(),
child: CircleAvatar(
radius: 25.0,
backgroundImage: AssetImage('assets/images/images.jfif'),

return Divider();
},
itemCount: 50),
),
floatingActionButton: FloatingActionButton(
backgroundColor: colour,
onPressed: () {},

}
}

try padding: EdgeInsets.zero inside ListView.separated, not inside ListTile

How to make a top tab bar with CupertinoSliverNavigationBar Flutter

I use CupertinoSliverNavigationBar, how can I add a tab bar below the title that is fixed to scroll?
My current code :
class SearchView extends StatefulWidget {
#override
_SearchViewState createState() => _SearchViewState();
}
class _SearchViewState extends State<SearchView> {
#override
Widget build(BuildContext context) {
return CupertinoPageScaffold(
child: NestedScrollView(
headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
return <Widget>[
CupertinoSliverNavigationBar(
backgroundColor: Colors.white,
border: Border.all(width: 0.0, color: const Color(0xFFFFFFFF)),
leading: Material(
child: GestureDetector(
onTap: () => Navigator.of(context).pop(),
child: Icon(
IconData(
0xe904,
fontFamily: 'icomoon',
),
color: Colors.black,
size: 25.0,
),
),
),
largeTitle: Text('Discover'),
)
];
},
body: Scaffold(
backgroundColor: Colors.white,
body: Container(),
),
),
);
}
}
Like on the attached picture :
Of course, if there is a solution that works without the Cupertino widgets, but that still respects the design, I'm interested.
You can use NeverScrollableScrollPhysics to ensure that the height of the CupertinoSliverNavigationBar remains fixed:
CupertinoPageScaffold(
child: CustomScrollView(
physics: const NeverScrollableScrollPhysics(), // add
slivers: [
CupertinoSliverNavigationBar(
middle: Text(
testNumber,
style: const TextStyle(
color: CupertinoColors.systemPink
),
),
largeTitle: const CircleAvatar(
backgroundColor: CupertinoColors.systemGreen,
child: Text("1"),
),
),
SliverFillRemaining(
child: PageView.builder(
itemBuilder: (context, index) {
return Text("$index");
},
),
)
],
)
);

I'm new to flutter and am trying to update the background color of a scaffold when a variable is changed. the variable is declared in another file. The reason why it needs to change?

}
You need to get the value of the DarkMode variable from a global variable like using an app state provider. Or you can send the DarkMode value as a parameter to the next page. The first one is a better use-case.
Your provider will look like this:
import 'package:flutter/material.dart';
class AppStateProvider with ChangeNotifier {
bool _darkMode = false;
bool get darkMode => this._darkMode;
void setDarkMode(bool value) {
this._darkMode = value;
}
}

How can I create a line under the SliverAppBar in flutter?

I would like to add a line under the appbar as in image two.
How can I make this line in flutter?
The image one is the app now and the image two is the line under the sliverAppBar
*already tried to use a container and a divider
class HomeScreen extends StatefulWidget {
#override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: CustomScrollView(
slivers: <Widget>[
SliverAppBar(
backgroundColor: Colors.white,
elevation: 0,
leading: IconButton(

floating: true,
),
SliverList(
delegate: SliverChildBuilderDelegate(
(context, index) => ListTile(title: Text('Item #$index')),
childCount: 1000,
),
),
],
),
);
}
}
more txt for the stack valid my questions
There is a 'bottom' attribute in the SliverAppBar Widget which takes a preferred size Widget, you can give it the following:
bottom: PreferredSize(
preferredSize: Size(double.infinity, 5),
child: Divider(color: Colors.black),
),
A contribution to omar hatem answer, the property "size" should be "preferredSize"
bottom: PreferredSize(
preferredSize: Size(double.infinity, 5),
child: Divider(color: Colors.black),
),
In my case, I needed more control over my line under the app bar sliver so I ended up implementing like so:
SliverPersistentHeader(
pinned: true,
delegate: MySliverElevationDelegate(
child: Material(
//elevation: 4.0,
child: Container(
color: Colors.black,
),
),
),
)

The solution provided by #Darshan is not solved my issue and the solution is
Wrap TabBar in SafeArea widget.
and the result is
How to remove this small bottom from appbar?
The reason is AppBar have its size + status bar size. There are multiple ways fix this. As other answer mentioned, simple way is to add SafeArea.
And note that even after you will get ugly little space under two tabs.
To solve that you can use PreferredSize (there are other ways for this also).
Code for the above screenshot:
class _TemplesListingWithTabModeState extends State<TemplesListingWithTabMode> {
#override
Widget build(BuildContext context) {
return DefaultTabController(
length: 2,
child: SafeArea(
child: Scaffold(
appBar: PreferredSize(
preferredSize: Size(double.infinity, 60),
child: TabBar(
indicatorColor: Colors.pink,
tabs: [
Tab(
child: Text("ALL",style: TextStyle(color: Colors.pink),),
),Tab(
child: Text("Favorites",style: TextStyle(color: Colors.pink),),
)
]),
),
body : Container(
color: Colors.grey,
child: TabBarView(
children: [
ListView.builder(
itemCount: 100,
itemBuilder: (context,index){
return Container(
child: Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text("i am $index"),
),
),
);
}),
ListView.builder(
itemCount: 5,
itemBuilder: (context,index){
return Container(
child: Center(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text("i am $index"),
),
),
);
})
]),
),
),
),
);
}
}
By default, ListView acts as if SafeArea is turned on.
Setting the padding to zero will remove that white space.
ListView(
padding: EdgeInsets.zero;
...
);
Discussion on ListView and the default SafeArea
Wrap TabBar in SafeArea widget. It adds the necessary padding to the child widget which in your case, minimizes the space you are seeing. Working code below:
child: Scaffold(
appBar: AppBar(
backgroundColor: Colors.white,
flexibleSpace: SafeArea(
child: TabBar(
indicatorColor: Colors.pink,
tabs: [
Tab(
child: Text("ALL",style: TextStyle(color: Colors.pink),),
),Tab(
child: Text("Favorites",style: TextStyle(color: Colors.pink),),
)
]),)
),
Hope this answers your question.
You can create your appbar by extending AppBar
class MyAppBar extends AppBar {
MyAppBar({PreferredSizeWidget child, Color backgroundColor})
: super(bottom: child, backgroundColor: backgroundColor);
#override
Size get preferredSize => bottom.preferredSize;
}
class TemplesListingWithTabMode extends StatefulWidget {
TemplesListingWithTabMode({Key key}) : super(key: key);
#override
_TemplesListingWithTabModeState createState() =>
_TemplesListingWithTabModeState();
}
class _TemplesListingWithTabModeState extends State<TemplesListingWithTabMode> {
#override
Widget build(BuildContext context) {
return DefaultTabController(
length: 2,
child: Scaffold(
appBar: MyAppBar(
backgroundColor: Colors.white,
child: TabBar(indicatorColor: Colors.pink, tabs: [
Tab(
child: Text(
"ALL",
style: TextStyle(color: Colors.pink),
),
),
Tab(
child: Text(
"Favorites",
style: TextStyle(color: Colors.pink),
),
)
]),
),
body: Container(
color: Colors.grey,
child: TabBarView(children: [
ListView.builder(
itemCount: 100,
