Single Child Scroll View not working for Bottom Overflowed Pixels
Question
My widgets just overflowed by 18 pixels, and when I add SingleChildScrollView() my screen just goes blank and every widget becomes invisible.
As shown in above img my widgets are overflowed by 18 pixels.
Here is my code for that :
(Note that I have added Common card widget in the same file, so the code may look lengthy but it's just repeated code)
import 'package:flutter/material.dart';
import 'package:google_fonts/google_fonts.dart';
class home extends StatefulWidget {
const home({Key? key}) : super(key: key);
@override
_homeState createState() => _homeState();
}
class _homeState extends State<home> {
@override
Widget build(BuildContext context) {

And when I wrap the widget with SingleChildScrollView() my screen goes blank as shown below:
Can anyone tell why it's happening and how can I resolve this?
Any help will be much appreciated :)

Try below code hope its helpful to you, Wrap your Column inside SingleChildScrollView refer documentaion here , Just change my icons with your images
Scaffold(
backgroundColor: Colors.blue[900],
resizeToAvoidBottomInset: true,
body: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
SizedBox(

Container(
padding: EdgeInsets.only(
top: 55.0, left: 30.0, right: 30.0, bottom: 30.0),
child: Row(
children: [
Column(
crossAxisAlignment: CrossAxisAlignment.start,
