Add this package to your dev dependency:

flutter pub add --dev dmg

Open a terminal on your current project then run:

dart run dmg --sign-certificate "Developer ID Application: Your  Company"

Change the notary profile name if you don't use the default by adding:

--notary-profile "NotaryProfile"

If you want to add a license (a window will shows up to ask for the acceptance before showing the installation for the .dmg), add this line to the above code:

--license-path "./path/to/license.txt"

You can also add your own setting.py of dmg-build by adding:

--setting "./path/to/setting.py"

Note that the --license-path will be ignored when you use your own setting.py.

Your output DMG is expected at: build/macos/Build/Products/Release/<name>.dmg.
