我将https://www.npmjs.com/package/react-bootstrap-dialog#dialogprompt-generators用于通知生成模块。但仅显示按钮，对话框中不显示任何文本消息。
onClick () {
this.dialog.show({
title: 'Greedings',
body: 'How are you?',
actions: [
Dialog.CancelAction(),
Dialog.OKAction()
],
bsSize: 'small',
onHide: (dialog) => {
dialog.hide()
console.log('closed by clicking background.')
}
})
}
这是我用于此的代码部分。帮帮我..
我在项目开发中使用了材质仪表板react free模板，因此在此对话框中不起作用，但是当我使用codeandbox时，它可以正常工作，它不能与材质仪表板一起使用吗？我不明白为什么，如果您知道，请帮助我。
