Row(
children: <Widget>[
RaisedButton(
padding: EdgeInsets.symmetric(horizontal: 30.0, vertical: 15.0),
textColor: Colors.black,
child: Text(
'LeaderBoard',
style: TextStyle(
fontSize: 20.0,
fontWeight: FontWeight.bold,
),
),
onPressed: () {
showDialog(
context: context,
builder: (BuildContext context) => leadDialog);
},
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(10.0)),
),
My Dialog mmethod
import 'package:flutter/material.dart';
Dialog leadDialog = Dialog(
child: Container(
height: 300.0,
width: 360.0,
color: Colors.white,

You need to change a structure of the code for it,
First you need to create one separate class for dialog(So you can pass data on it),
Then you need to create custom tile class for this kind of List View tile.
Then you need to create list view in your custom dialog and call those tiles in your list view.
And at your button click event just pass data at calling the dialog.
