title: Button(KivyMD)- MDRoundFlatIcon I can't add radius to button and move icon right
body: <p>I'm working on an interface using KivyMD. In this work, I need to use DropDownMenu. I also created MDRoundFlatIconButton for this. I want to play with the dimensions of the button to fit the design I have, but I cannot add a radius to the button. Also, I can't get the &quot;menu-down&quot; icon right there.</p>
  <p>I leave the design I need to create and the codes I use below. If you think that this design can be done in a different way, please write your suggestions.</p>
  <p><strong>.kv codes:</strong></p>
  <pre><code>MDRoundFlatIconButton:
                  size_hint: .25, .049 
                  line_color: 0, 0, 0, 1
                  text:&quot;English&quot;
                  font_name: &quot;assets/font/SF-Pro-Rounded-Light.otf&quot;
                  font_size: &quot;14sp&quot;
                  icon: &quot;menu-down&quot;
                  icon_color: get_color_from_hex(&quot;#000000&quot;)
                  pos_hint: {&quot;center_x&quot;:0.6729, &quot;center_y&quot;:0.0441}
                  theme_text_color: &quot;Custom&quot;
                  text_color: get_color_from_hex(&quot;#000000&quot;)
