检查一下是不是连接了真机。
这边出现的情况是在打开模拟器的时候还连接了真机。
把真机给拔了就可以了。
可能的原因是真机没有点击信任机器。

pub get failed (65)

what I meet the question is directly return Scaffold

return new Scaffold(
        appBar: new AppBar(
          title: new Text('demo'),
        ),
        body:Text('test')
    );

instead of return MaterialApp is solve this question.

return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text('demo'),
        ),
        body:Text('test')
      ),
    );

电脑新搭建的环境，flutter create创建了一个demo，flutter run的时候出现了VM snapshot must be valid. Check failed: vm. Must be able to initialize the VM.这个问题，小白google了一天都无法解决！！大佬能给个解决思路吗？
