I have no issue with it using GTK under the hood, as long as it doesn't inherit the philosophy of "dependencies are installed using your system package manager" to the degree that GTK does.
Another thing I would like to avoid is the philosophy of "the application binary doesn't come with its dependencies bundled, the user should install them using the system package manager". Unfortunately, many frameworks have this philosophy but, apparently, Flutter doesn't.
