Hi, my code might help you:

def show_toast(self, preset, title, text):
        preset_mapping = {
            "success": (ToastPreset.SUCCESS, ToastPreset.SUCCESS_DARK),
            "warning": (ToastPreset.WARNING, ToastPreset.WARNING_DARK),
            "error": (ToastPreset.ERROR, ToastPreset.ERROR_DARK),
            "info": (ToastPreset.INFORMATION, ToastPreset.INFORMATION_DARK),
        }

        current_theme = self.model.theme
        is_dark_theme = current_theme == "dark"

        toast = Toast(self.view)
        toast.setDuration(3000)
        toast.setTitle(title)
        toast.setText(text)

        # Select the appropriate preset based on the theme
        selected_preset = preset_mapping[preset.lower()][is_dark_theme]
        toast.applyPreset(selected_preset)

        toast.show()

Hi,

[PySidde6 v6.7.3, OS LinuxMint] QMainWindow has no model.theme.

Damage. Your code didn't help me.
I tried the darktheme autodetect module but it doesn't work.

Damage. Your code didn't help me. I tried the darktheme autodetect module but it doesn't work.

Its normal, model.theme is specific go my app, I created this variable to store the current theme, I didnt meant to just copy paste my code.

If you're using macOS, then you can check if OS dark mode is set using the func below. If you're using windows or prefer a pypi package, then check out darkdetect.

   import subprocess
    
   def is_dark_mode() -> bool:
        """
        Determines whether the system is currently in dark mode.

        The method executes a shell command to read the global AppleInterfaceStyle setting and interprets the output to ascertain if dark mode is enabled.

        Returns:
            bool: True if dark mode is active, False otherwise.
        """
        cmd = 'defaults read -g AppleInterfaceStyle'
        p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
        return bool(p.communicate()[0])

You could pair this with @Crackvignoule code snippet and replace:

    current_theme = self.model.theme
    is_dark_theme = current_theme == "dark"

with this:

    is_dark_theme =  is_dark_mode()
