Stack的可叠加视图（Positioned 控制底部按钮位置）；
ListView显示中间滑动卡片地址信息；

代码中几个使用的地方，可以直接用下面方法替换，
import 'dart:ffi';
import 'package:flutter/material.dart';
import 'dart:io';
class ConstantTool {
static final bool kIsAndroid = Platform.isAndroid;
}
class CommonData {
// 数据
static MediaQueryData queryData = (MediaQueryData.fromWindow(window));
// 获取屏幕size
static final Size size = (queryData.size);
// 屏幕高
static final double screenH = (size.height);
// 屏幕宽
static final double screenW = (size.width);
}
