纳闷昨天运行还好好的，今天就报错了，一顿查找,github上：
https://github.com/flutter/flutter/issues/19257
具体解决方法：执行flutter channel master即可，切换到官方master开发主分支即可
执行 flutter channel查看当前我的flutter处于stable(稳定)分支，然后在官网上看到这一句话：
我们强烈建议跟踪flutter的stable分支，这是Flutter稳定分支。 如果你需要查看最新的变化，你可以跟踪master分支，但注意这是开发分支，所以稳定性要低得多。
要查看您当前使用的分支，请运行flutter channel查看。
要切换分支，请使用flutter channel beta 或 flutter channel master
所以我想我的问题应该不是切换分支的问题，最后想想是不是clean一下项目试试:
MacBook-Pro-65:flutter_app hello$ flutter clean
Cleaning Xcode workspace... 2.7s
Deleting build... 747ms
Deleting .dart_tool... 7ms
MacBook-Pro-65:flutter_app hello$
结束后，重新运行项目，结果顺利跑起来了。
