If you are using Flutter on Linux, and you installed Google Chrome using Flapak, you may face the problem when installing and running Flutter:

Flutter required Google Chrome path to be set in: CHROME_EXECUTABLE. Here is how you can do that, as you find your Google Chrome binary, then set your it:

export CHROME_EXECUTABLE=/var/lib/flatpak/exports/bin/com.google.Chrome
