#

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

Operating system

#

Flutter supports ChromeOS.

Development tools

#

To develop Flutter on ChromeOS:

  1. Enable Linux on your Chromebook.

  2. 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

  3. To develop Android apps:

    1. Install the following prerequisite packages for Android Studio:

      sudo apt-get install libc6:amd64 libstdc++6:amd64 lib32z1 libbz2-1.0: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.

When you run the current version of flutter doctor, it might list a different version of one of these packages. If it does, install the version it recommends.

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

Configure a text editor or IDE

#

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:

Install the Flutter SDK

#

To install the Flutter SDK, you can use the VS Code Flutter extension or download and install the Flutter bundle yourself.

Use VS Code to install Flutter

#

To install Flutter using these instructions, verify that you have installed Visual Studio Code 1.77 or later and the Flutter extension for VS Code.

Prompt VS Code to install Flutter

#

  1. Launch VS Code.

  2. To open the Command Palette, press Control + Shift + P.

  3. In the Command Palette, type flutter.

  4. Select Flutter: New Project.

  5. VS Code prompts you to locate the Flutter SDK on your computer.

    1. If you have the Flutter SDK installed, click Locate SDK.

    2. If you do not have the Flutter SDK installed, click Download SDK.

      This option sends you the Flutter install page if you have not installed Git as directed in the development tools prerequisites.

  6. When prompted Which Flutter template?, ignore it. Press Esc. You can create a test project after checking your development setup.

Download the Flutter SDK

#

  1. When the Select Folder for Flutter SDK dialog displays, choose where you want to install Flutter.

    VS Code places you in your user profile to start. Choose a different location.

    Consider ~/development/

  2. Click Clone Flutter.

    While downloading Flutter, VS Code displays this pop-up notification:

    Downloading the Flutter SDK. This may take a few minutes.

    This download takes a few minutes. If you suspect that the download has hung, click Cancel then start the installation again.

  3. Once it finishes downloading Flutter, the Output panel displays.

    Checking Dart SDK version...
Downloading Dart SDK from the Flutter engine ...
Expanding downloaded archive...

    When successful, VS Code displays this pop-up notification:

    Initializing the Flutter SDK. This may take a few minutes.

    While initializing, the Output panel displays the following:

    Building flutter tool...
Running pub upgrade...
Resolving dependencies...
Got dependencies.
Downloading Material fonts...
Downloading Gradle Wrapper...
Downloading package sky_engine...
Downloading flutter_patched_sdk tools...
Downloading flutter_patched_sdk_product tools...
Downloading windows-x64 tools...
Downloading windows-x64/font-subset tools...

    This process also runs flutter doctor -v. At this point in the procedure, ignore this output. Flutter Doctor might show errors that don't apply to this quick start.

    When the Flutter install succeeds, VS Code displays this pop-up notification:

    Do you want to add the Flutter SDK to PATH so it's accessible
in external terminals?

  4. VS Code may display a Google Analytics notice.

    If you agree, click OK.

  5. To enable flutter in all Terminal windows:

    1. Close, then reopen all Terminal windows.
    2. Restart VS Code.

Download then install Flutter

#

To install Flutter, download the Flutter SDK bundle from its archive, move the bundle to where you want it stored, then extract the SDK.

  1. Download the following installation bundle to get the latest stable release of the Flutter SDK.

    (loading...)

    For other release channels, and older builds, check out the SDK archive.

    The Flutter SDK should download to the ChromeOS default download directory: ~/Downloads/.

  2. Create a folder where you can install Flutter.

    Consider creating a directory at ~/development/.

  3. Extract the file into the directory you want to store the Flutter SDK.

    tar -xf ~/Downloads/flutter_sdk_v1.0.0.zip -C ~/development/

    When finished, the Flutter SDK should be in the ~/development/flutter directory.

Add Flutter to your PATH

#

To run Flutter commands in a shell, add Flutter to the PATH environment variable.

  1. Check which shell starts when you open a new console window. This would be your default shell.

    echo $SHELL

    This differs from another command that tells you which shell runs in your current console.

    echo $0

  2. To add Flutter to your PATH, expand the entry for your default shell, then choose the command.

    Show bash command
    echo 'export PATH="~/development/flutter/bin:$PATH"' >> ~/.bash_profile
    Show zsh command
    echo 'export PATH="~/development/flutter/bin:$PATH"' >> ~/.zshenv
    Show fish command
    fish_add_path -g -p ~/development/flutter/bin
    Show csh command
    echo 'setenv PATH "~/development/flutter/bin:$PATH"' >> ~/.cshrc
    Show tcsh command
    echo 'setenv PATH "~/development/flutter/bin:$PATH"' >> ~/.tcshrc
    Show ksh command
    echo 'export PATH="~/development/flutter/bin:$PATH"' >> ~/.profile
    Show sh command
    echo 'export PATH="~/development/flutter/bin:$PATH"' >> ~/.profile

  3. To apply this change, restart all open terminal sessions.

How to fix the error of finding Java install

You might have an issue with the Android SDK locating the Java SDK.

flutter doctor --android-licenses

ERROR: JAVA_HOME is set to an invalid directory: /Applications/Android\ Studio.app/Contents/jre/Contents/Home

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

Android sdkmanager tool was found, but failed to run
(/Users/atsansone/Library/Android/sdk/cmdline-tools/latest/bin/sdkmanager): "exited code 1".
Try re-installing or updating your Android SDK,
visit https://flutter.dev/to/macos-android-setup for detailed instructions.

The flutter doctor command returns this error because of how the JAVA_HOME variable was set. When you add the path to JAVA_HOME, you can add a backslash to the space between Android and Studio or enclose the entire path in matching quotes. You cannot do both.

Look for your JAVA_HOME path in your appropriate shell resource file.

Change it from:

bash
export JAVA_HOME="/Applications/Android\ Studio.app/Contents/jre/Contents/Home"

to:

bash
export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/Contents/Home"

Do not include the backslash between Android and Studio.

To load this updated environment variable, reload your shell. This example uses the zsh resource file.

source ~/.zshrc

Check your development setup

Run Flutter doctor

#

The flutter doctor command validates that all components of a complete Flutter development environment for ChromeOS.

  1. Open a shell.

  2. To verify your installation of all the components, run the following command.

    flutter doctor

As you chose to develop for Android, you do not need all components. If you followed this guide, the result of your command should resemble:

Running flutter doctor...
