I’m trying to make a music app and I’m in trouble with modifying positions of ‘Playlist of the week’ text and the Listview of the images right now. I want to make those two properties more upwards but I have no idea what to do.
This is my home.dart file
import 'package:flutter/material.dart';
import 'package:secondlife_mobile/PageViewHolder.dart';
import 'package:provider/provider.dart';
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key});
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final PageStorageBucket bucket = PageStorageBucket();
late PageViewHolder holder;
late PageController _controller;
double fraction =
0.57; // By using this fraction, we're telling the PageView to show the 50% of the previous and the next page area along with the main page
@override
void initState() {
super.initState();
holder = PageViewHolder(value: 2.0);
_controller = PageController(initialPage: 2, viewportFraction: fraction);
_controller.addListener(() {
holder.setValue(_controller.page);
});
}
int index = 1;
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
backgroundColor: const Color.fromARGB(255, 223, 234, 244),
appBar: AppBar(
backgroundColor: Colors.transparent,
centerTitle: true,
title: const Text('AppBar'),
),
body: SingleChildScrollView(
child: SizedBox(
height: MediaQuery.of(context).size.height,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
const SizedBox(
height: 30,
),
const Padding(
padding: EdgeInsets.symmetric(horizontal: 35),
child: Text(
'Playlist for you',
style: TextStyle(
fontSize: 20,
fontWeight: FontWeight.w400,
),
),
),
const SizedBox(height: 35),
Container(
child: Center(
child: AspectRatio(
aspectRatio: 1,
child: ChangeNotifierProvider<PageViewHolder>.value(
value: holder,
child: PageView.builder(
controller: _controller,
itemCount: 4,
physics: const BouncingScrollPhysics(),
itemBuilder: (context, index) {
return MyPage(
number: index.toDouble(),
fraction: fraction,
);
}),
),

),
),

class MyPage extends StatelessWidget {
final number;
final double? fraction;
const MyPage({super.key, this.number, this.fraction});
@override
Widget build(BuildContext context) {
double? value = Provider.of<PageViewHolder>(context).value;
double diff = (number - value);
// diff is negative = left page
// diff is 0 = current page
// diff is positive = next page
//Matrix for Elements
final Matrix4 pvMatrix = Matrix4.identity()
..setEntry(3, 2, 1 / 0.9) //Increasing Scale by 90%
..setEntry(1, 1, fraction!) //Changing Scale Along Y Axis
..setEntry(3, 0, 0.004 * -diff); //Changing Perspective Along X Axis
final Matrix4 shadowMatrix = Matrix4.identity()
..setEntry(3, 3, 1 / 1.6) //Increasing Scale by 60%
..setEntry(3, 1, -0.004) //Changing Scale Along Y Axis
..setEntry(3, 0, 0.002 * diff) //Changing Perspective along X Axis
..rotateX(1.309); //Rotating Shadow along X Axis
return Stack(
fit: StackFit.expand,
alignment: FractionalOffset.center,
children: [
Transform.translate(
offset: const Offset(0.0, -47.5),
child: Transform(
transform: pvMatrix,
alignment: FractionalOffset.center,
child: Container(
decoration: BoxDecoration(boxShadow: [
BoxShadow(
color: Colors.grey.withOpacity(0.5),
blurRadius: 11.0,
spreadRadius: 4.0,
offset: const Offset(
13.0, 35.0), // shadow direction: bottom right
)
]),
child: Image.asset(
"assets/images/image_${number.toInt() + 1}.jpg",
fit: BoxFit.fill),
),
),
),
],
);
}
}And this is the image that I’m expecting right now.

Yeah, I solved it with wrapping the Padding of both text and the ListView with Transform.translate and did some tinkering with the offset.
Thank God I solved this! :)
Try to place a column inside the singlechildscrollview and define mainaxisalignment as min
Set
heightproperty ofContainerwidget wrappingPageView.
