Im just starting out with flutter and I’m having some trouble moving an asset image towards the bottom of the screen. Im currently working on a login screen, there are text widgets, text fields, and a sign on button, If I used a sized box the way I have it setup it pushes these elements up, whilst I want them to stay where they are, which is in the center of the screen.
class _LoginPageState extends State<LoginPage> {
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: SafeArea(
child: Column(mainAxisAlignment: MainAxisAlignment.center, children: [
SizedBox(height: 10),
// hello!
Text(
'(REDACTED)',
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 25,
),
key: Key("bigText"),
),
SizedBox(height: 10),
Text(
'Welcome Back!',
style: TextStyle(
fontSize: 24,
),
),
SizedBox(height: 20),
// username
Padding(
padding: const EdgeInsets.symmetric(horizontal: 25.0),
child: Container(
decoration: BoxDecoration(
color: Colors.grey[200],
border: Border.all(color: Colors.white),
borderRadius: BorderRadius.circular(12),
),
child: Padding(
padding: const EdgeInsets.only(left: 30.0),
child: TextField(
decoration: InputDecoration(
border: InputBorder.none, hintText: 'Username'),
),
),
),
),
SizedBox(height: 15),
// Password section copied from above
Padding(
padding: const EdgeInsets.symmetric(horizontal: 25.0),
child: Container(
decoration: BoxDecoration(
color: Colors.grey[200],
border: Border.all(color: Colors.white),
borderRadius: BorderRadius.circular(12),
),
child: Padding(
padding: const EdgeInsets.only(left: 30.0),
child: TextField(
obscureText: true,
decoration: InputDecoration(
border: InputBorder.none, hintText: 'Password'),
),
),
),
),
SizedBox(height: 25),
// sign in button
Padding(
padding: const EdgeInsets.symmetric(horizontal: 40.0),
child: GestureDetector(
//onTap: signOn(),
child: Container(
padding: EdgeInsets.all(20),
decoration: BoxDecoration(
color: Colors.cyan,
borderRadius: BorderRadius.circular(30),
),
child: Center(
child: Text('Sign In',
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.bold,
fontSize: 18,
)),
),
),
),
),
SizedBox(height: 20),
Image.asset(
'assets/FMJ.png',
// The height controls its size for some reason
height: 100,
),
]),
),
);
}
}
>Solution :
try putting a spacer at the top and bottom (above the image), like this:
class _LoginPageState extends State<LoginPage> {
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: SafeArea(
child: Column(mainAxisAlignment: MainAxisAlignment.center, children: [
const Spacer(),
// hello!
Text(
'(REDACTED)',
style: TextStyle(
fontWeight: FontWeight.bold,
fontSize: 25,
),
key: Key("bigText"),
),
SizedBox(height: 10),
Text(
'Welcome Back!',
style: TextStyle(
fontSize: 24,
),
),
SizedBox(height: 20),
// username
Padding(
padding: const EdgeInsets.symmetric(horizontal: 25.0),
child: Container(
decoration: BoxDecoration(
color: Colors.grey[200],
border: Border.all(color: Colors.white),
borderRadius: BorderRadius.circular(12),
),
child: Padding(
padding: const EdgeInsets.only(left: 30.0),
child: TextField(
decoration: InputDecoration(
border: InputBorder.none, hintText: 'Username'),
),
),
),
),
SizedBox(height: 15),
// Password section copied from above

child: TextField(

),
),
),
),
SizedBox(height: 25),
// sign in button
Padding(

child: GestureDetector(
//onTap: signOn(),
child: Container(
padding: EdgeInsets.all(20),

borderRadius: BorderRadius.circular(30),
),
child: Center(
child: Text('Sign In',
style: TextStyle(

fontSize: 18,
)),
),
),
),
),
const Spacer(),
Image.asset(
'assets/FMJ.png',
// The height controls its size for some reason
height: 100,
),
]),
),
);
}
}
