获取store的方法是build方法使用Provider.of<HomeStore>(context)可以得到对应的store,这样虽然我们可以得到store但是在build方法里面会导致我们在页面跳转的时候或者切换页面的时候执行重新请求数据，我们想要的不是这个，而是下拉刷新来获取新的数据。如果在build里面发送请求会出现的用户滑动到某个位置回来以后数据重新请求导致重新构建。查看performance控制台你会发现内部的组件在疯狂的rebuild,为了数据能够共享还是在initState去发送请求，具体代码如下：
@override
void initState() {
// TODO: implement initState
super.initState();
Future.delayed(Duration.zero, () {
// 获取对应的store
homeStore = Provider.of<HomeStore>(this.context);
// 发送请求
homeStore.getData();
});

错误信息
* What went wrong:
A problem occurred evaluating project ':app'.
> D:\project\flutter_book\android\key.properties在<app dir>/android/目录下，创建一个key.properties文件<app dir>代表工程的根目录,在key.properties写入
复制粘贴即可，如果需要打包发布APP需要配置以下信息，而且要生成key.jks文件,这里只是让项目可以运行，如果需要发布详细请看https://flutter.dev/docs/deployment/android。
storePassword=<password from previous step>
keyPassword=<password from previous step>
keyAlias=key
storeFile=<location of the key store file, e.g. /Users/<user name>/key.jks>storePassword keystore 密码
keyPassword key密码
keyAlias key别名
storeFile .jks文件路径
