#### Parameters

| | |
| --- | --- |
| onDismissRequest | called 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. |
| confirmButton | 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. |
| modifier | the `Modifier` to be applied to this dialog |
| dismissButton | 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. |
| icon | optional icon that will appear above the `title` or above the `text`, in case a title was not provided. |
| title | title which should specify the purpose of the dialog. The title is not mandatory, because there may be sufficient information inside the `text`. |
| text | text which presents the details regarding the dialog's purpose. |
| shape | defines the shape of this dialog's container |
| containerColor | the color used for the background of this dialog. Use `Color.Transparent` to have no color. |
| iconContentColor | the content color used for the icon. |
| titleContentColor | the content color used for the title. |
| textContentColor | the content color used for the text. |
| tonalElevation | when `containerColor` is `ColorScheme.surface`, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: `Surface`. |
| properties | typically platform specific properties to further configure the dialog. |
