Start building Flutter Android apps on ChromeOS

To install and run Flutter, your ChromeOS environment must meet the following hardware and software requirements.

Your ChromeOS Flutter development environment must meet the following minimal hardware requirements.

To discover which hardware devices ChromeOS recommends for Android development, consult the ChromeOS docs.

To write and compile Flutter code for Android, you must have the following version of ChromeOS and the listed software packages.

Flutter supports ChromeOS.

To develop Flutter on ChromeOS:

1. Enable Linux on your Chromebook.

2. Verify that you have the following tools installed: bash, file, mkdir, rm, which

   which bash file mkdir rm which
   /bin/bash
   /usr/bin/file
   /bin/mkdir
   /bin/rm
   which: shell built-in command

3. Install the following packages: curl, git, unzip, xz-utils, zip, libglu1-mesa

   sudo apt-get update -y && sudo apt-get upgrade -y;
   sudo apt-get install -y curl git unzip xz-utils zip libglu1-mesa

4. To develop Android apps:

   1. Install the following prerequisite packages for Android Studio.

      sudo apt-get install \
          libc6:amd64 libstdc++6:amd64 \
          libbz2-1.0:amd64 libncurses5:amd64

   2. Install Android Studio 2023.3.1 (Jellyfish) or later to debug and compile Java or Kotlin code for Android. Flutter requires the full version of Android Studio.

当你在当前版本运行 flutter doctor 的时候，它可能会列出这些软件包的其他不同版本。如果出现这种情况，请安装它推荐的版本。

The developers of the preceding software provide support for those products. To troubleshoot installation issues, consult that product's documentation.

You can build apps with Flutter using any text editor or integrated development environment (IDE) combined with Flutter's command-line tools.

Using an IDE with a Flutter extension or plugin provides code completion, syntax highlighting, widget editing assists, debugging, and other features.

Popular options include:

• Visual Studio Code 1.77 or later with the Flutter extension for VS Code.
• Android Studio 2023.3.1 (Jellyfish) or later with the Flutter plugin for IntelliJ.
• IntelliJ IDEA 2023.3 or later with the Flutter plugin for IntelliJ.

你可以使用 VS Code Flutter 扩展或自行下载安装 Flutter 压缩包，来安装 Flutter SDK。

在使用 Flutter 之前，按照指南安装所有必要的条件之后，再同意 Android SDK 平台的许可证。

1. 打开一个高权限（管理员）的控制台窗口。

2. 运行以下指令启用签名许可证。

   flutter doctor --android-licenses

   如果你在其他时候已经同意了 Android Studio 许可证，该指令将会返回：

   [========================================] 100% Computing updates...
   All SDK package licenses accepted.

   你可以跳过下一个步骤。

3. 请仔细阅读每项许可条款后，再同意。

flutter doctor --android-licenses

flutter doctor 指令将检查 ChromeOS 完整的 Flutter 开发环境的所有组件。

1. Open 一个 shell.

   打开一个 shell。

2. 要检查所有组件的安装情况，请运行以下指令。

   flutter doctor

由于你选择为 Android 进行开发，因此不需要 所有 组件。如果你遵循本指南，指令结果应该类似于：

Running flutter doctor...
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 3.24.0, on , locale en)
[✓] Android toolchain - develop for Android devices (Android SDK version 35.0.1)
[!] Chrome - develop for the web
[✓] Android Studio (version 2024.1)
[✓] VS Code (version 1.92)
[✓] Connected device (1 available)
[✓] Network resources


! Doctor found issues in 2 categories.

当 flutter doctor 指令返回错误时，可能是 Flutter、VS Code、、连接的设备或者网络资源出错。

如果 flutter doctor 指令返回这些组件中的任何一个错误，请使用 verbose 标志再次运行。

flutter doctor -v

查看输出结果，了解可能需要安装的其他软件或者需要执行的其他任务。

如果你更改了 Flutter SDK 或其他相关组件的配置，请 再次运行 flutter doctor 来检查安装。

恭喜你。 在安装完成所有必要条件和 Flutter SDK 后，你就可以开始开发适用于 Android on ChromeOS 的 Flutter 应用了。
