How can I give Linear gradient to my entire flutter app? - android

Here's the code,
The problem is that there is a gap of black colour around the rounded corners due to theme data being black. I can't fill it with gradient present in the above container. image has been attached. any solution?
class _TrackListState extends State<TrackList> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
child: Container(
height: double.infinity,
//child: Text('hello'),
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Color(0xFF04DCB6), Color(0xFF6DE079)]),
),
child: Column(
children: <Widget>[],
),
),
),
Expanded(
flex: 3,
child: Container(
//padding: EdgeInsets.symmetric(horizontal: 20),
foregroundDecoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.only(
topLeft: Radius.circular(30),
topRight: Radius.circular(30),
),
),
),
)
],
),
),
);
}
}
The image where I am having the problem


I tested it on DartPad. Give it a try. Using stack, you can fill the background and draw on top of it.
#override
Widget build(BuildContext context) {
return Stack(
fit: StackFit.expand,
children: <Widget>[
Container(
decoration: BoxDecoration(
gradient:
LinearGradient(colors: [Color(0xFF04DCB6), Color(0xFF6DE079)]),
),
),
Positioned.fill(
top: 80,
child: Container(
foregroundDecoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.only(
topLeft: Radius.circular(30),
topRight: Radius.circular(30),
),
),
),
),
],
);
}

How can I add an Icon to to Box Decoration?

I want to add an Icon to Box Decoration like this you are seeing images on left side.
How do I add this with box decoration
Here is the code:
Container(
width: 307,
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent),
borderRadius: BorderRadius.circular(10.0),
shape: BoxShape.rectangle,
),
child: CountryListPick(
onChanged: (list){
print(list?.name);
},
theme: CountryTheme(
labelColor: Colors.white,
isShowFlag:true,
isShowCode: false,
isShowTitle:true,
isDownIcon: true,
showEnglishName: true,
),
),
),

You can use this widget for a textfield with boxdecoration and icon:
TextFormField(
key: Key(key),
controller: controller,
decoration: InputDecoration(
prefixIcon: Icon(icon), // <-- left icon
hintText: hintText,
border: OutlineInputBorder( //<--- decoration border
borderRadius: BorderRadius.all(Radius.circular(90.0)),
borderSide: BorderSide.none,
),
filled: true,
),
)

You can use a row as a children of container
Container(
width: 307,
decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent),
borderRadius: BorderRadius.circular(10.0),
shape: BoxShape.rectangle,
),
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Flexible(
child: Image.asset(
"assets/images/cover_placeholder.png",
height: 30,
width: 30,
fit: BoxFit.contain,
),
),
SizedBox(width: 12,),
Flexible(
child: CountryListPick(
onChanged: (list){
print(list?.name);
},
theme: CountryTheme(
labelColor: Colors.white,
isShowFlag:true,
isShowCode: false,
isShowTitle:true,
isDownIcon: true,
showEnglishName: true,
),
),
),
],
),
),

So you can use SizedBox or Container -
SizedBox(
width: 300.0,
height: 120.0,
child: Padding(
padding: const EdgeInsets.all(5.0),
child: Container(
child: Row(
children: <Widget>[
Material(
type: MaterialType.transparency,
child: Stack(
children: <Widget>[
Column(
children: <Widget>[
Container(
padding: const EdgeInsets.only(
top: 1.0, bottom: 1.0, right: 5.0),
height: 50.0,
width: 50.0,
decoration: BoxDecoration(
borderRadius:
BorderRadius.circular(15.0),
color: Colors.green[50],
),
child: IconButton(
icon: Icon(Icons.favorite),
color: Colors.red[700],
highlightColor: Colors.red,
onPressed: () {},
),
),
],
),
],
),
),
],
),
),
),
),

Try this solution:
/// Add with AutomaticKeepAliveClientMixin:
class _YourWidgetState extends State<YourWidget> with AutomaticKeepAliveClientMixin {
/// Add these 2 lines:
#override
bool get wantKeepAlive => true;
/// Add super.build(context) to your build method
#override
Widget build(BuildContext context) {
super.build(context);
return YourWidgets();
}
}

flutter: Add a Text at the bottom of Scaffold

I am new to flutter. In my home screen I want to add a text at the bottom of the Screen displayed
home page code
Scaffold buildUnAuthScreen(){
return Scaffold(
body: Container(
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topRight,
end: Alignment.bottomLeft,
colors: [
Theme.of(context).accentColor,
Theme.of(context).primaryColor,
]
),
),
alignment: Alignment.center,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Text('FriendsHive',
style: TextStyle(
fontFamily: 'Signatra',
fontSize: 90.0,
color: Colors.white,
) ,
),
GestureDetector(
onTap: login,
child: Container(
width: 260.0,
height: 60.0,
decoration: BoxDecoration(
image: DecorationImage(image: AssetImage('assets/images/google_signin_button.png'),
fit: BoxFit.cover,
),
),
),
),
],
),
),
);
}
result
In this screen I want to add a text that will be displayed at the bottom. I tried an example but when I apply that, text is shown at bottom but the main text and the button goes up, I don't want that to happen.

you can use this code
Expanded(
child: Align(
alignment: FractionalOffset.bottomCenter,
child: Text('You can try'),
),
),
or
bottomNavigationBar: BottomAppBar(
color: Colors.transparent,
child: Text('something'),
elevation: 0,
),

you can wrap your column with stack and in stack use positioned widget like code below
Scaffold(
body: Container(
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topRight,
end: Alignment.bottomLeft,
colors: [
Theme.of(context).accentColor,
Theme.of(context).primaryColor,
]),
),
alignment: Alignment.center,
child: Stack(
children: <Widget>[
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Text(
'FriendsHive',
style: TextStyle(
fontFamily: 'Signatra',
fontSize: 90.0,
color: Colors.white,
),
),
GestureDetector(
onTap: () {},
child: Container(
width: 260.0,
height: 60.0,
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage(
'assets/images/google_signin_button.png'),
fit: BoxFit.cover,
),
),
),
),
],
),
Positioned(
bottom: 0,
right: 0,
left: 0,
child: Center(child: Text('test')),
)
],
)),
);

Flutter | border radius not apply on Android

I want to find out why border radius wouldn't apply top half of the widget on Android.
Here is the image on Android
However on the web, it's working like image below.
Does anyone know why?
Code
Center(
child: Card(
elevation: 1.5,
shape: RoundedRectangleBorder(borderRadius: BorderRadius.all(Radius.circular(16.0))),
child: SizedBox(
width: 250.0,
height: 150.0,
child: Column(
children: <Widget>[
Container(
width: double.infinity,
height: 60.0,
color: Colors.pink[200].withOpacity(0.95),
child: Center(
child: Text('Felicity Jones'),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Center(
child: Text('9:15'),
),
),
)
],
),
),
),
),

If you observe carefully by changing the opacity of the color for time being to:
color: Colors.pink[200].withOpacity(0.2),
You'll see that the top left and top right corners are cut-off and not filled by the color:
In order to avoid this, use Card widget's clipBehavior: Clip.antiAlias, property that covers all corners of the card with the given color. Here's the updated result:
Hope this answers your question.

You can try the following:
Center(
child:
Card(
elevation: 1.5,
shape: RoundedRectangleBorder(borderRadius: BorderRadius.all(Radius.circular(16.0))),
child: SizedBox(
width: 250.0,
height: 150.0,
child: Column(
children: <Widget>[
Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.vertical(
top: new Radius.circular(16.0)
),
color: Colors.pink[200].withOpacity(0.95),
),
width: double.infinity,
height: 60.0,
child: Center(
child: Text('Felicity Jones'),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Center(
child: Text('9:15'),
),
),
)
],
),
),
),
),
Note that the color was moved inside the BoxDecoration as it will fail to compile otherwise.
I kept the shape attribute so that the lower part of the card will be rounded as well. You could tinker with that and remove it, if necessary.

Edit: In your case like #Darshan mentioned you can just set clipBehavior: Clip.antiAlias in Card widget.
You can use also use ClipRRect to force the child to have the given border radius, if you don't have clipBehavior.
Center(
child: Card(
elevation: 1.5,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(16.0),
),
child: ClipRRect(
borderRadius: BorderRadius.circular(16.0),
child: SizedBox(
width: 250.0,
height: 150.0,
child: Column(
children: <Widget>[
Container(
width: double.infinity,
height: 60.0,
color: Colors.pink[200].withOpacity(0.95),
child: Center(
child: Text('Felicity Jones'),
),
),
Expanded(
child: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Center(
child: Text('9:15'),
),
),
)
],
),
),
),
),
)

SingleChildScrollView height to max height with image background in flutter

In the Login screen, there is a background image and all stuff will be scrollable but SingleChildScrollView is not showing macth_parent height. My aim is to design like here
class MyLoginOne extends StatelessWidget {
#override
Widget build(BuildContext context) {
return new Scaffold(
body: new Container(
decoration: new BoxDecoration(
image: new DecorationImage(
fit: BoxFit.cover,
image:new NetworkImage('https://i.pinimg.com/originals/c2/47/e9/c247e913a0214313045a8a5c39f8522b.jpg')
)
),
child: new BackdropFilter(
filter:new ImageFilter.blur(sigmaX: 1.1,sigmaY:1.1),
child: new Container(
decoration: new BoxDecoration(color: Colors.black45.withOpacity(0.5)),
child: new SingleChildScrollView(
child: new Container(
child: new Column(
children: <Widget>[
new Container(
height: 200.0,
child: new Stack(
children: <Widget>[
new Align(
alignment: AlignmentDirectional.center,
child:new Container(
height: 120.0,
width: 120.0,
decoration: new BoxDecoration(
shape: BoxShape.circle,
color: Colors.white30
),
)
),
new Align(
alignment: AlignmentDirectional.center,
child: new Container(
child: new Text("Farha",style: new TextStyle(
color: Colors.white,
fontSize: 14.0,
fontFamily: "WorkSansLight"
),),
),),],))],),),)),), ));}}
my circle container height is about 200.0 but SingleChildScrollView is not showing full height.

Code of the required layout - its not 100% but get the job Done. You can Complete it as required.
#override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children: <Widget>[
Container(
decoration: new BoxDecoration(
image: new DecorationImage(
fit: BoxFit.cover,
image: new NetworkImage(
'https://i.pinimg.com/originals/c2/47/e9/c247e913a0214313045a8a5c39f8522b.jpg'))),
),
Center(
child: SingleChildScrollView(
padding: EdgeInsets.all(30.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
CircleAvatar(
radius: 58.0,
child: Text('Travel'),
),
SizedBox(
height: 20.0,
),
TextFormField(
decoration: InputDecoration(
prefixIcon: Icon(
Icons.person,
color: Colors.white,

TextFormField(
decoration: InputDecoration(

prefixIcon: Icon(Icons.lock, color: Colors.white),
hintStyle: TextStyle(color: Colors.white),
fillColor: Colors.black45,
hintText: 'Password'),
),
SizedBox(
height: 15.0,
),
FlatButton(
onPressed: () {},
child: Text(
'Forgot your Password?',
style: TextStyle(color: Colors.white),
)),
SizedBox(
height: 15.0,
),
RaisedButton(
onPressed: () {},
child: Padding(
padding: EdgeInsets.all(15.0),
child: Text('LOGIN')),
color: Colors.redAccent,
textColor: Colors.white,
),
SizedBox(
height: 10.0,
),
RaisedButton(
onPressed: () {},
child: Padding(
padding: EdgeInsets.all(15.0),
child: Text('REGISTER')),
color: Colors.grey,
textColor: Colors.white,
),
SizedBox(
height: 12.0,
),
Row(
children: <Widget>[
Expanded(
child: Divider(
color: Colors.white,
height: 8.0,
),
),
SizedBox(
width: 8.0,
),
Text(
'OR',
style: TextStyle(color: Colors.white),
),
SizedBox(
width: 8.0,
),
Expanded(
child: Divider(
color: Colors.white,
height: 8.0,
),
)
],
),
Row(
children: <Widget>[
// TODO Social Icons
],
),
],
),
),
),
],
),
);
}
OutPut:

A Container widget will size themselves to its child, unless specified.
In your case:
...
Container(
height: double.infinity, // <-----
decoration: new BoxDecoration(
image: new DecorationImage(
fit: BoxFit.cover,
image: new NetworkImage(
'https://i.pinimg.com/originals/c2/47/e9/c247e913a0214313045a8a5c39f8522b.jpg')))
...
