+ *
+ * Alert dialogs interrupt users with urgent information, details, or actions.
+ *
+ * ![Dialogs image](https://developer.android.com/images/reference/androidx/compose/material/dialogs.png)
+ *
+ * The dialog will position its buttons based on the available space. By default it will try to
+ * place them horizontally next to each other and fallback to horizontal placement if not enough
+ * space is available. There is also another version of this composable that has a slot for buttons
+ * to provide custom buttons layout.
+ *
+ * @param onDismissRequest Executes when the user tries to dismiss the Dialog by clicking outside
+ * or pressing the back button. This is not called when the dismiss button is clicked.
+ * @param confirmButton A button which is meant to confirm a proposed action, thus resolving
+ * what triggered the dialog. The dialog does not set up any events for this button so they need
+ * to be set up by the caller.
+ * @param modifier Modifier to be applied to the layout of the dialog.
+ * @param dismissButton A button which is meant to dismiss the dialog. The dialog does not set up
+ * any events for this button so they need to be set up by the caller.
+ * @param title The title of the Dialog which should specify the purpose of the Dialog. The title
+ * is not mandatory, because there may be sufficient information inside the [text]. Provided text
+ * style will be [Typography.subtitle1].
+ * @param text The text which presents the details regarding the Dialog's purpose. Provided text
+ * style will be [Typography.body2].
+ * @param shape Defines the Dialog's shape
+ * @param backgroundColor The background color of the dialog.
+ * @param contentColor The preferred content color provided by this dialog to its children.
+ * @param properties Typically platform specific properties to further configure the dialog.
