I have tried to define the Input decoration to change the color of underline of input TextField. But it's not working. can anyone suggest what am i missing here ?
Here is the Code snippet :
decoration: InputDecoration( hintText: 'Username', hintStyle: TextStyle(color: Colors.white), border: new UnderlineInputBorder( borderSide: BorderSide(color: Colors.white, width: 1.0, style: BorderStyle.none ), ), 
decoration: InputDecoration( hintText: 'Username', hintStyle: TextStyle(color: Colors.white), enabledBorder: new UnderlineInputBorder( borderSide: BorderSide( color: Colors.white, width: 1.0, style: BorderStyle.none ), ), ), Just change border to enabledBorder. Hope this help!
We have to use both enabledBorder and focusedBorder.
enabledBorder: It will work when TextField not having focus. focusedBorder: It will work when TextField has the focus.enabledBorder: new UnderlineInputBorder( borderSide: BorderSide( color: Colors.black ), ), // and: focusedBorder: new UnderlineInputBorder( borderSide: BorderSide( color: Colors.black ), ), You have to put widget hierarchy under MaterialApp.
class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return new MaterialApp( title: 'Flutter WebView Demo', theme: new ThemeData( primarySwatch: Colors.blue, ), home: new Container( **//put widget here.** )); } } Just used -:
decoration: InputDecoration( focusedBorder: UnderlineInputBorder( borderSide: BorderSide(color: Colors.cyan), ), ), it works for me :)
You can wrap your TextField in Theme and change accentColor like:
Theme( data: Theme.of(context).copyWith(accentColor: Colors.red), child: TextField(), ) If you want change that blue line color, used this below code..it works
focusedBorder: OutlineInputBorder(borderSide: BorderSide(color: Colors.grey) 
child: TextField( controller: email, enabled: true, keyboardType: TextInputType.emailAddress, decoration: InputDecoration( filled: true, fillColor: Color(0xFFF2F2F2), enabledBorder: new OutlineInputBorder( borderSide: new BorderSide(color: Colors.orange)), focusedBorder: OutlineInputBorder( borderSide: BorderSide(color: Colors.orange), ), hintText: ' Email ', icon: Icon( Icons.email, color: Colors.orange, size: 30.0, ), ) )
