+val customView = ExampleCustomView(context)
+customDialog {
+    title = SpannableStringBuilder().color(Color.RED) { append("Custom Dialog Sample") }
+    showCloseButton = true
+    animateCornerRadiusWhenExpand = false
+    cornerRadius = 0F
+    closeButtonListener = infoDialogClosed
+    titleBackgroundColor = R.color.colorAccent
