Flutter 如何运行与颤振捆绑在一起的示例

我有一个Flatter0.5.1测试版，我试着用它来运行hello world，但它不起作用 所以我决定用dev版本检查它，但它仍然不工作，请检查以下代码片段以了解更多详细信息：

$~/StudioProjects/flutter/examples/hello_world$ flutter --version
Flutter 0.5.7 • channel dev • https://github.com/flutter/flutter.git
Framework • revision 66091f9696 (10 days ago) • 2018-07-09 12:52:41 -0700
Engine • revision 6fe748490d
Tools • Dart 2.0.0-dev.63.0.flutter-4c9689c1d2

$~/StudioProjects/flutter/examples/hello_world$ flutter doctor

$~/StudioProjects/flutter/examples/hello_world$ flutter run
Running "flutter packages get" in hello_world...                 
Because hello_world depends on flutter_test any from sdk which depends on watcher 0.9.7+8, watcher 0.9.7+8 is required.
So, because hello_world depends on watcher 0.9.7+9, version solving failed.
pub get failed (1)

当我尝试运行其他示例时，会发生以下情况：

$~/Flutter.0.5.7/examples/catalog$ flutter run

As per the comments on the question the examples might not work in cases when the Flutter distribution is not updated or when you are on channel other then beta(stable or canary?) 
you can execute this commands and see if it works or not.


flutter channel beta #switch to beta channel
flutter packages get #update the packages?

根据对该问题的评论，当颤振分布未更新时，或当您处于beta以外的通道（稳定或金丝雀？）时，示例可能不起作用
您可以执行这些命令，看看它是否有效

尝试
flatterchannelbeta
，然后再次尝试
flatterpackages
。@GünterZöchbauer我尝试了这个flatterchannelbeta>flatterrun（hello world）>它显示黑屏，中间有hello world文本，这很好，之后我尝试运行目录示例，但我看到了与screenshot.platform_channel中显示的相同的内容，platform_view似乎适用于beta频道Flatter_gallery也适用于beta频道：）很高兴听到：）
