Q:

Flutter I want to design the interface like this, can you guys help me? I am designing an about page but I am having problems

I have just learned and fluttered and am trying to design an about page. I am having difficulty in the card of flutter. I need a complete demo board to refer to the next issue.

A:

You can use package expandable 
full code 
import 'package:expandable/expandable.dart';
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Expandable Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  State createState() {
    return MyHomePageState();
  }
}

class MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("About DTC"),
      ),
      body: ListView(
        children: <Widget>[
          Text(
            loremIpsum,
            softWrap: true,
            overflow: TextOverflow.fade,
          ),
          Card1(),
          Card2(),
        ],
      ),
    );
  }
}

const loremIpsum =
    "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
