Targeting ChromeOS with Android

This page discusses considerations unique to building Android apps that support ChromeOS with Flutter.

Flutter & ChromeOS tips & tricks


For the current versions of ChromeOS, only certain ports from Linux are exposed to the rest of the environment. Here's an example of how to launch Flutter DevTools for an Android app with ports that will work:

flutter pub global run devtools --port 8000
cd path/to/your/app
flutter run --observatory-port=8080

Then, navigate to in your Chrome browser and enter the URL to your application. The last flutter run command you just ran should output a URL similar to the format of Use this URL and select "Connect" to start the Flutter DevTools for your Android app.

Flutter ChromeOS lint analysis


Flutter has ChromeOS-specific lint analysis checks to make sure that the app that you're building works well on ChromeOS. It looks for things like required hardware in your Android Manifest that aren't available on ChromeOS devices, permissions that imply requests for unsupported hardware, as well as other properties or code that would bring a lesser experience on these devices.

To activate these, you need to create a new analysis_options.yaml file in your project folder to include these options. (If you have an existing analysis_options.yaml file, you can update it)

include: package:flutter/analysis_options_user.yaml

To run these from the command line, use the following command:

flutter analyze

Sample output for this command might look like:

Analyzing ...
warning • This hardware feature is not supported on ChromeOS •
android/app/src/main/AndroidManifest.xml:4:33 • unsupported_chrome_os_hardware
