How do I use guilayout toggle event to check if true or false?

Question

OnGUI()
{
            for (int i = 0; i < scenes; i++)
            {
                GUILayout.Toggle(false, SceneManager.GetSceneAt(i).name);
            }

            if (GUILayout.Toggle(true, "New Scene"))
            {
                Debug.Log("True now !");
            }
}

First in the loop I'm adding some toggles. Then I want to do that if specific toggle is checked(true) do something and if unchecked(false) do something else.

But the way I did it it's just changing the toggle to true automatic.

The idiom with most of these GUI controls is to store a member variable representing the current state / value held inside the control. When you draw the control, you pass that variable so that it's drawn in the correct state. The function then returns the new value of the variable based on user input.

bool isToggleChecked;

void OnGUI() {
    isToggleChecked = GUILayout.Toggle(isToggleChecked, "Toggle Name");

    if(isToggleChecked) {
        // What to do if the toggle is in the checked state
    } else {
        // What to do if the toggle is in the unchecked state
    }
}
