@Input() `name: string \| null`	如果存在，name 值就会被应用到输入元素中。 Name value will be applied to the input element if present.
@Input() `required: boolean`	滑块开关是否为必填项。 Whether the slide-toggle is required.

`MatSlideToggleRequiredValidator`

Material 滑块开关组件的验证器，在模板驱动表单中具有 required 属性。默认的验证器需要表单控件确保其值不是 undefined，但是这对于永远是已定义值的滑块开关是不合适的。

Validator for Material slide-toggle components with the required attribute in a template-driven form. The default validator for required form controls asserts that the control value is not undefined but that is not appropriate for a slide-toggle where the value is always defined.

当检查时，滑块开关表单控件的必填项验证总是有效的。

Required slide-toggle form controls are valid when checked.
