For Ubuntu 20.04, chromium is managed by snap. I set the environment variable as shown below.

CHROME_EXECUTABLE=/snap/bin/chromium
export CHROME_EXECUTABLE

Try 'type chromium' to make sure of the location on your system. I assume something similar will work for chrome.

For ones who use MacOS and with another chromium-based browser than Google Chrome (Brave in my case). You can set in .zshrc or .bashrc

export CHROME_EXECUTABLE="/Applications/Brave Browser.app/Contents/MacOS/Brave Browser"

After that, don't forget to source ~/.zshrc or source ~/.bashrc in the current terminal window.

flutter doctor -v

Now, "Chrome" will be seen as "Brave".

I had the same error in Windows 10, Using VS Code even after setting CHROME_EXECUTABLE system environmental variable to the path of chrome.exe. I solved it by removing the double quotes around the path:

Even though you have a google chrome app in your system. It may have command like google-chrome-stable or chrome or any name to open chrome browser from terminal. Just duplicate the file with google-chrome name in /usr/bin/

Eg: I have google-chrome-stable as executable so my approach is like

sudo cp /usr/bin/google-chrome-stable /usr/bin/google-chrome

You may have bin in snap folder or some other folder depending on your installation way

If you're not having chrome as executable from terminal then create a symbolic link. Find you chrome binary file and use this command

sudo ln -s $PATH/[google-chrome-bin] /usr/bin/google-chrome

Replace [google-chrome-bin] with your binary file name

I'm on a Chromebook. I installed Flutter and Android Studio. When I ran $flutter doctor -v, I got the same error message that you got.

I didn't need to export the file path to my path environment. I just needed to install Chrome so that Flutter could find it on my Chromebook.

Here was the command that worked for me:

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

Then I installed it using the Linux beta command (right click on the downloaded file, install using Linux beta). It installed it to this directory:

/usr/bin/

(Alternatively, for the install, I could've used this command:

sudo apt install ./google-chrome-stable_current_amd64.deb)

I ran flutter doctor -v and now it finds Chrome.

you can export PATH in your .bashrc or .zshrc if you use Linux or MAC OS you can found installed chrome PATH using which

for example

which google-chrome
# example result : /opt/google/chrome/google-chrome

then add to .zshrc or .bashrc like this

# Chrome PATH
export PATH=$PATH:/opt/google/chrome

then restart source

source .zshrc # change if you use .bashrc

running the flutter doctor

you will see the output like this

The answers here have helped me setup Flutter on Mac with Microsoft Edge instead of Chrome. For that, you simply run from your terminal:

export CHROME_EXECUTABLE="/Applications/Microsoft Edge.app/Contents/MacOS/Microsoft Edge"

If you want to make this permanent, you should add the above line to the file

~/.zshenv or ~/.zshrc

Then save and restart terminal.

For Linux users, you can add Edge Browser like this...

first, add this path in .bashrc file path

PATH=$PATH:/usr/bin/microsoft-edge-stable

then execute this command

export CHROME_EXECUTABLE="/usr/bin/microsoft-edge-stable"

in my case it was because the name of my chrome was "google chrome 2.app" i renamed it to "google chrome.app"

You can also try with just chrome instead of google-chrome.

For MacOS Users

1. cd to /Users/<your user>
2. sudo nano ~/.zshenv
3. Add the following:

export PATH="$PATH:/Applications/Microsoft Edge.app/Contents/MacOS/Microsoft Edge"
export CHROME_EXECUTABLE="/Applications/Microsoft Edge.app/Contents/MacOS/Microsoft Edge"

4. Save the file and restart the IDE terminal
5. Run flutter doctor
