使用 Flutter 在 VSCode 中未检测到模拟器

Question

我正在尝试使用模拟器，当我启动它时，它开始加载，但在 VSCode 中没有连接。如何连接以便 VSCode 检测到它？

当我启动 adb-server 时，我得到以下输出

Answer 1

设备没有权限。运行flutter doctor和flutter devices，如果似乎没有设备连接（在本例中为模拟），您需要kill打开adb-server模拟器，然后启动adb-server。

如果此后问题仍然存在，请尝试flutter doctor --android licenses

如果仍然继续，请发布您的flutter doctor&flutter devices输出。
