 ### Properties
 * `width` (Number) - Width of the Callout (default is 200)
+* `backgroundColor` (String) - Sets the background color of the callout (default is #EF4836)
 * `arrowDirection` (Enum) - Directions for the arrow of the callout, namely: up, down, left & right
 * `visibility` (Number) - Set 0 for hiding the callout and 1 to show the callout
 * `calloutText` (String) - Text to be shown inside the callout,
+* `calloutView` (Component) - Component to be shown inside the callout (takes precedence over `calloutText`),
+* `textStyle` ({}) - Extends the styles of the `calloutText` view
+* `caretStyle`: ({}) - Extends the styles of the caret of the callout
+* `calloutSquareStyle` ({}) - Extends the styles of the container of the callout
