/**
* toast 消息提示
* @description 此组件表现形式类似uni的uni.showToastAPI,但也有不同的地方。
* @tutorial https://www.uviewui.com/components/toast.html
* @property {String | Number} zIndex toast展示时的zIndex值 (默认 10090 )
* @property {Boolean} loading 是否加载中 (默认 false )
* @property {String | Number} message 显示的文字内容
* @property {String} icon 图标,或者绝对路径的图片
* @property {String} type 主题类型 (默认 default)
* @property {Boolean} show 是否显示该组件 (默认 false)
* @property {Boolean} overlay 是否显示透明遮罩,防止点击穿透 (默认 false )
* @property {String} position 位置 (默认 'center' )
* @property {Object} params 跳转的参数
* @property {String | Number} duration 展示时间,单位ms (默认 2000 )
* @property {Boolean} isTab 是否返回的为tab页面 (默认 false )
* @property {String} url toast消失后是否跳转页面,有则跳转,优先级高于back参数
* @property {Function} complete 执行完后的回调函数
* @property {Boolean} back 结束toast是否自动返回上一页 (默认 false )
* @property {Object} customStyle 组件的样式,对象形式
* @event {Function} show 显示toast,如需一进入页面就显示toast,请在onReady生命周期调用
* @example <u-toast ref="uToast" />
