flutter - Flutter 未安装在 UBUNTU 20.04 LTS 上

Question

我在 Ubuntu 20.04 LTS 上。我安装了颤振 SDK sudo snap install flutter --classic，然后我安装了 android studio，sudo snap install andriod-studio --classic但是当我 flutter doctor在终端中运行时，它输出：

[✓] Flutter (Channel stable, 2.0.3, on Linux, locale en_US.UTF-8)
[!] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/linux#android-setup for
      more details.
[✓] Chrome - develop for the web
[!] Android Studio (not installed)
[✓] Connected device (1 available)

! Doctor found issues in 2 categories

N 当我在 VS 代码中打开任何颤振项目并flutter run在终端连接物理设备进行调试时，它说：

我只想在我的 android 手机上运行颤振项目进行调试。所以有人可以告诉我这里的问题吗？任何帮助，将不胜感激！！！

Answer 1

Read the errors when they appear. It's clearly saying two things, with steps how to solve them:

1: run flutter doctor --android-licenses.

2: install android studio.

3: Install android studio from here on linux, not by using snap.
