this is the login screen I had Implemented using flutter. I want this screen to be scrollable. how can I do that? I have uploaded my login screen code for your reference. I have tried out my column wrap with a single-child scroll view. but it doesn't work. there are multiple columns, maybe I'm wrapping the wrong column. I appriciate your help on this.
class LoginScreen extends StatefulWidget {
const LoginScreen({Key? key}) : super(key: key);
@override
_LoginScreenState createState() => _LoginScreenState();
}
class _LoginScreenState extends State<LoginScreen> {
@override
Widget build(BuildContext context) {
final Size = MediaQuery.of(context).size;

onTap: () => FocusManager.instance.primaryFocus?.unfocus(),

CodePudding user response：
You should wrap everything under the Scaffold:
Scaffold(
backgroundColor: Colors.transparent,
resizeToAvoidBottomInset: false,
body: SingleChildScrollView(child: Padding(
padding: const EdgeInsets.only(top: 40, left: 20, right: 20),
child: Column(
........
CodePudding user response：
I can not see you using the SingleChildScrollView in then code sample you have provided with.
But if you want to make the page scrollable, Wrap the child of the scaffold in the SingleChildScrollView
Scaffold(
body: SingleChildScrollView(
....
