How to add underline to unselected tabs, like this:
Here you can see it is gray colour for unselected tabs, and blue for selected.
I haven't found any reference in the documentation about how to customize disabled indicator. However, you can build your own widget that will take additional decoration parameter:
class DecoratedTabBar extends StatelessWidget implements PreferredSizeWidget {
DecoratedTabBar({@required this.tabBar, @required this.decoration});
final TabBar tabBar;
final BoxDecoration decoration;
@override
Size get preferredSize => tabBar.preferredSize;
@override
Widget build(BuildContext context) {
return Stack(
children: [
Positioned.fill(child: Container(decoration: decoration)),
tabBar,
],
);
}
}
Then you can decorate your TabBar however you want:
appBar: AppBar(
bottom: DecoratedTabBar(
tabBar: TabBar(
tabs: [
// ...
],
),
decoration: BoxDecoration(
border: Border(
bottom: BorderSide(
color: Colors.blue,
width: 2.0,
),
),
),
),
),
Which will result in desired behavior:
TabBar(
indicatorColor: Color(0xffF15C22),
unselectedLabelColor: Colors.black,
labelColor: Color(0xffF15C22),
tabs: [
Tab(text: "Tab 1"),
Tab(text: "Tab 2"),
Tab(text: "Tab 3"),
],
),
indicatorColor is the property which is helpful in changing the color of line in tab view
I know I'm answering late, but this will eventually help a lot of people. What you have to do is to follow the same thing which is mentioned in the decoration by @tomwyr
You don't have to make your own widget for that, just do this and there you go.
class CustomTabBarMenu extends StatefulWidget {
@override
_CustomTabBarMenuState createState() => _CustomTabBarMenuState();
}
class _CustomTabBarMenuState extends State<CustomTabBarMenu>
with SingleTickerProviderStateMixin{
TabController _controller;
@override
void initState() {
// TODO: implement initState
super.initState();
_controller = new TabController(length: YOUR_LENGTH, vsync: this);
}
@override
Widget build(BuildContext context) {
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
//This is responsible for the background of the tabbar, does the magic
decoration: BoxDecoration(
//This is for background color
color: Colors.white.withOpacity(0.0),
//This is for bottom border that is needed
border: Border(bottom: BorderSide(color: Colors.grey, width: 0.8))),
child: TabBar(
controller: _controller,
tabs: [
...
]
)
),
Container(
height: MediaQuery.of(context).size.height/2.3,
child: new TabBarView(
controller: _controller,
children: <Widget>[
...
],
)
)
]
);
}
}
RESULT
The best way to it is like this :
Scaffold(
appBar: AppBar(
titleSpacing : 0 ,
automaticallyImplyLeading: false,
elevation: 0,
title: Container(
width: double.infinity,
decoration: BoxDecoration(
color: Colors.white,
border: Border(
bottom: BorderSide(color: Colors.grey, width: 0.8))),
child: TabBar(
unselectedLabelColor: Colors.grey,
unselectedLabelStyle: TextStyle(
fontWeight: FontWeight.w700,
fontSize: 16,
color: Color.fromRGBO(142, 142, 142, 1)),
labelColor: Colors.blue,
labelPadding: EdgeInsets.fromLTRB(0, toppadding, 0, 8),
labelStyle: TextStyle(
fontFamily: "Roboto",
fontSize: 16,
fontWeight: FontWeight.w700,
),
controller: tabController,
indicatorColor: Colors.blue,
indicator: UnderlineTabIndicator(
borderSide:
BorderSide(color: Colors.grey, width: 2.0),
),
tabs: [
Text(
'Title1',
),
Text(
'Title2',
),
])),
),
body: TabBarView(
controller: tabController,
children: <Widget>[Container(), Container()],
),
),
You can just envolve the DefaultTabController with a Theme Widget and pass the color in indicatorColor in ThemeData.
Theme(
data: ThemeData(
indicatorColor: Colors.red,
),
child: DefaultTabController(
length: 2,
child: Scaffold(
appBar: AppBar(
title: Text('Example =)'),
You can try using this package ! its pretty simple, just add the indicator to your tab bar's indicator property
bottom: TabBar(
isScrollable: true,
indicatorSize: TabBarIndicatorSize.label,
labelColor: Theme.of(context).accentColor,
unselectedLabelColor: Color(0xff5f6368),
**indicator: MD2Indicator(
indicatorHeight: 3,
indicatorColor: Theme.of(context).accentColor,
indicatorSize: MD2IndicatorSize.full),**
tabs: Constants.tabItems,
),
This post had previously been deleted because I put it in two places. I deleted the other post because this is the best place for it to be. A similar question can be found here: How to create unselected indicator for tab bar in Flutter
I believe the best answer is to wrap the tab bar in a Material widget, and give it an elevation (I chose an elevation of 1.) After that, you can customize the shadow color of the Material Widget.
Material(
type: MaterialType.canvas,
shadowColor: Colors.orange, //Custom unselected underline color
elevation: 1.0, //Create underline for entire tab bar
child: Container(
color: Color(0xFFe3f2fd), //Gives tab bar a background color
child: TabBar(tabs:
[Tab(text: 'ACTIVITY'),
Tab(text: 'LEADERBOARD',),
Tab(text: 'SETTINGS',)],
labelColor: Theme.of(context).primaryColor,
indicatorColor: Theme.of(context).primaryColor,
labelStyle: TextStyle(
fontWeight: FontWeight.bold,
fontFamily: 'Montserrat'),
indicatorPadding:
EdgeInsets.symmetric(horizontal: 20.0),
),
),
),
You add this in tab bar
indicator: BoxDecoration(
border: Border(
bottom: BorderSide(
color: Colors.white,
width: 2.0,
),
),
),
and you come up with something like this
TabBar(
labelColor: Colors.white,
indicator: BoxDecoration(
border: Border(
bottom: BorderSide(
color: Colors.white,
width: 2.0,
),
),
),
tabs: [
Tab(child:
FxText.titleMedium("Pofile", fontWeight: 600,color: Colors.white,)),
Tab(
child: FxText.titleMedium(
"Events",
fontWeight: 600,color: Colors.white)),
],
)
