先做一下错误(❎)示范：

import PropTypes from 'prop-types';

static propTypes = {
    containerStyle: PropTypes.style,
}

结果：

Warning: Failed prop type: LocationIndex: prop type containerStyle is invalid; it must be a function, usually from the prop-types package, but received undefined .

大致意思是说： prop-types 中根本没有定义style 类型。

但是实际开发中确实需要验证style类型有怎么办呢？

方法一：

import { ViewPropTypes } from 'react-native';
import PropTypes from 'prop-types';

static propTypes = {
    containerStyle: ViewPropTypes.style,
}

方法二：

import PropTypes from 'prop-types';

static propTypes = {
    containerStyle: PropTypes.oneOfType([PropTypes.object, PropTypes.array]),
}
