如何在ng2-material对话框中添加图标？

Question

我有一个对话框，当发生某些事情时，它会显示，这是它的代码：

 public showMessageDialog(message) {
    let config = new MdDialogConfig()
      .title('Dialog Box:')
      .textContent(message)
      .ok('Got it') .;

    this.dialog.open(MdDialogBasic, this.element, config);
  }

现在我有一些表情符号图标，我想在触发该框时添加它。

因此：
