我对Flutter感到非常困惑。我7年前为Windows Phone创建了一个具有以下屏幕的应用程序:
谁能告诉我要用Flutter创建此屏幕的布局小部件(甚至是什么顺序?)?
我计划使用Flutter Studio设计和生成代码。希望能帮助我掌握。

这是我的实现的样子:
和代码:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
home: MyHomePage(),
theme: ThemeData(
primaryColor: Colors.white,
brightness: Brightness.light,

);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return SafeArea(

显然,您将需要动态填充ListView,使用填充进行播放,为OneDrive图标导入Font Awesome,使用auto_size_text包以确保文本在大多数设备上都能正常缩放(此屏幕截图来自Nexus) 5;字体在Pixel XL上看起来太小了),也许可以用适当的AppBar替换当前标题,等等,但这足以让您入门
