柯里化異步函數的流程 [signature-verification-failure]

Question

我收到以下錯誤：

type Submit = {
  form: any,
  handleSubmit: FunctionType<any, any>,
  ...
}
Flow-IDE

Submit: type Submit = {
    form: any,
    handleSubmit: FunctionType < any,
    any > ,
    ...
}
Cannot build a typed interface for this module. You should annotate the exports of this module with types. Missing type annotation at function return:Flow(signature-verification-failure)
Cannot build a typed interface for this module. You should annotate the exports of this module with types. Missing type annotation at function return: [signature-verification-failure] (index.js:31:11)flow

我有這個功能

type Submit = {
  form: Object,
  handleSubmit: FunctionType<Object, any> // this is our custom type, works fine
};

export const onClickSubmit = ({
  form,
  handleSubmit
}: Submit) => async (input: Object): Promise<any> => {
  await handleSubmit(input);
  form.reset();
};

突出顯示的區域是}: Submit) the ) 。

我不知道它要我做什么，在):之后添加任何類型定義根本沒有幫助。

類型優先流程文檔中的示例提供的示例沒有幫助。 我不能像在他們的 module.exports 示例中那樣export functionName具有特殊定義的 functionName。

Answer 1

你可以試試：

const onClickSubmit = ({
  form,
  handleSubmit
}: Submit) => async (input: Object): Promise<any> => {
  await handleSubmit(input);
  form.reset();
};

export onClickSubmit;

Answer 2

比我想象的要簡單，發布后馬上就明白了

type Submit = {
  form: Object,
  handleSubmit: FunctionType<Object, any>
};

const onClickSubmit = ({
  form,
  handleSubmit
}: Submit): FunctionType<Object, any> => async (input: Object): Promise<any> => {
  await handleSubmit(input);
  form.reset();
};
