请问 VScode,如何安装

有图片资源引用，selector写法的对比嘛

汝甚叼，家翁知否？

一直有个疑问，不知道博主是否知道？

MaterailApp 启动路由设置那里的 initialRoute 参数和 home 参数的设置貌似有点重复，因为在 routes 表里面已经有一个映射值了， 搞不懂google为啥这样设计。而且我测试过不设置 initialRoute ，只写 home 参数可以进启动页，但只设置 initialRoute，不设置 home 参数就会报错，一直没搞明白这一点，网上的资料目前也搜不到这点

flutter demo报错The built-in library 'dart:ui' is not available on the stand-alone VM.

关于Flutter中的StatefulWidget小优化 一文，按你的写法：
abstract class usefulStatefulWidget extends _Stateful with State<StatefulWidget> {}
报错：The class 'State' can't be used as a mixin because it extends a class other than Object.

官方的Demo 大概的依赖是这样的:
rxdart : ^0.16.7
rx_command: ^1.0.8
rx_widgets: ^1.0.3
报错如下:
Because rx_command <1.1.0 depends on rxdart ^0.16.6 and no versions of rx_command match >1.1.0 <2.0.0, rx_command <1.1.0-∞ or >1.1.0 <2.0.0 requires rxdart ^0.16.6.
And because rx_command 1.1.0 depends on rxdart ^0.16.7, rx_command <2.0.0 requires rxdart ^0.16.6.
So, because flutter_app depends on both rxdart ^0.18.0 and rx_command ^1.0.8, version solving failed.

第102行到109行前面的空格使用tab自动空格会出类型错误，改成空格的就没事了。
问题code：
" @OverRide",
" Path getClip(Size size) {",
" //TODO:",
" }",
"",
" @OverRide",
" bool shouldReclip(CustomClipper oldClipper) => false;",
" }",
