如何使用Flow在React中添加多态道具

Question

如何将多态道具添加到React组件？

我尝试了以下内容，但结果是：

T. This type is incompatible with some incompatible instantiation of T

示例：

/* @flow */
import React from 'react';

type Props<T> = {
  promise: () => Promise<T>
}

export default class Async<T> extends React.Component {
    props: Props<T>;
}

Answer 1

奇怪的错误，你可以试试这个

/* @flow */
import React from 'react';

type Props<T> = {
  promise: () => Promise<T>
}

export default class Async<T> extends React.Component<*, Props<T>, *> {}
