新安装的颤振/飞镖顺利进行，没有问题..运行“颤振医生-v”给出以下输出：

但尝试运行默认启动应用程序“flutter/material.dart”会导致...“无法找到开发设备；请运行“flutter doctor”以获取有关安装其他组件的信息”...无论我是否使用 Intellij或 Visual Studio。
然而，
$ flutter devices
1 connected device:
Pixel XL • HT69R0205363 • android-arm64 • Android 9 (API 28)
我在网上搜索并发现了类似的投诉..但没有解决方案。我希望有人能够对此有所了解，因为我确信它一定是简单而直接的。
Visual Studio 是一个新安装，但我现在每天都使用 Intellij 6 个月，并且很少遇到问题.. 尤其是我无法修复的问题。:)
先感谢您。
