我正尝试在我的手机上使用我的 flutter 应用程序，但是当我运行

但我无法在手机上使用午餐应用程序 phone。

我是flutter医生：

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel unknown, 2.0.6, on Linux, locale en_US.UTF-8)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
[✓] Chrome - develop for the web
[✓] Android Studio
[✓] VS Code (version 1.56.2)

我正在使用 FVM。我的手机 android 版本是 11.

当我运行 adb install /mnt/SSDP/Project/Casp/mobileapplication/build/app/outputs/flutter-apk/app.apk 卡在 执行流式安装 。

Answer 1

你扑频道未知.

the version is unknown and seems to be on web developer mode so

如果您在 android 设备上使用它，最好切换到

flutter channel stable

之后

flutter upgrade

然后 flutter run

Answer 2

我终于解决了这个问题:

运行 flutter doctor -v 如果你遇到 insufficient permissions for device 错误，你应该使用以下技巧：

根据official site

如果您看到一条错误消息，提示您不在 plugdev 组中，您需要将自己添加到 plugdev 组：

sudo usermod -aG plugdev $LOGNAME

然后：

android-sdk-platform-tools-common 软件包包含社区维护的 Android 设备的默认 udev 规则集。安装：

apt-get install android-sdk-platform-tools-common

如果以上提示无效:

adb kill-server

然后用超级用户启动adb或者使用sudo

sudo adb start-server

完成:-)
