单选按钮组是用于容纳一组单选按钮的容器。它允许用户从一组选项中选择最多一个。选中属于同一单选按钮组中的某个按钮时，之前在该组内选中的任何其他按钮都会自动取消选中。关于单选按钮组的具体用法示例，请参阅单选按钮文档。
接口
RadioGroupChangeEventDetail
interface RadioGroupChangeEventDetail<T = any> {
value: T;
}
RadioGroupCustomEvent
虽然不强制使用，但可以用此接口替代 CustomEvent 接口，以便在使用该组件发出的 Ionic 事件时获得更强的类型支持。
interface RadioGroupCustomEvent<T = any> extends CustomEvent {
detail: RadioGroupChangeEventDetail<T>;
target: HTMLIonRadioGroupElement;
}
