对于怎么动态隐藏和显示，我实践了一下，可以在setState里面动态添加布局，不添加时即可隐藏，添加时即可显示。 setState(() {
if (toggle) {
return new Text('Toggle One');
}
});

显示和隐藏使用 Offstage 里面有一个属性 offstage默认为true（隐藏），设置为false就会显示，

CachedNetworkImage
图片加载成功，怎么还一直loading？

嗯，在canvas绘制的时候，CustomPaint绘制区域没有Size，不能进行绘制，需要加上一个属性size : new Size(double.infinity, double.infinity)才能绘制出来

@wendux 配置完依赖点击pub get后出现这个错误怎么解决？
D:\software\flutter\bin\flutter.bat --no-color pub get
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git [...] -- [...]'
Running "flutter pub get" in my_first_flutter_app...
The current Flutter SDK version is 0.0.0-unknown.

Because myfirstflutterapp depends on cached_network_image >=2.0.0-rc which requires Flutter SDK version >=1.10.15-pre.148 <2.0.0, version solving failed.
pub get failed (1; Because myfirstflutterapp depends on cached_network_image >=2.0.0-rc which requires Flutter SDK version >=1.10.15-pre.148 <2.0.0, version solving failed.)
Process finished with exit code 1

我yaml文件的配置是
environment:
sdk: ">=2.7.0 <3.0.0"

dependencies:
cached_network_image: ^2.2.0+1
flutter:
sdk: flutter

解决了。安装flutter以下载压缩包方式会有问题，采用clone方式安装什么问题都没有了。建议flutter中文网也可以改为推荐clone方式。
