Need Help: GUI Toggle Deselects When Editor Window Closed

I had a quick question regarding Unity Editor Windows and wondered if anyone could help me or point me to someone who could. I made a GUI toggle but when it is selected and you close the window, the next time you open the window it is deselected. Is there a way to make it stay on if clicked?

Code (CSharp):

1. public bool DarkMode { get; private set; }
2.  
3. DarkMode = EditorGUILayout.ToggleLeft("Enable Dark Mode", DarkMode);
4.  
5.             if (DarkMode)
6.                 GUI.backgroundColor = new Color32(60, 60, 60, 255);
7.             else
8.                 GUI.backgroundColor = Color.white;

I wrote the code to change my text blocks to a dark grey if the toggle is selected

 

You can use EditorPrefs to make the selected value persist even if the window is closed.

Code (CSharp):

1. public bool DarkMode
2. {
3.     get
4.     {
5.         return EditorPrefs.GetBool("DarkMode");
6.     }
7.    
8.     set
9.     {
10.         return EditorPrefs.SetBool("DarkMode", value);
11.     }
12. }

 

Thanks a lot! I wasn't even aware of EditorPrefs but it worked like a charm!
