我有一个返回 React Native 的 TypeScript 函数View。
import React from "react";
import JSX, {View} from "react-native";
class DummyClass {
static getView() {
return (
<View style={{flex: 1}}/>
);
}
}
export default DummyClass;
我以这种方式调用这个函数：
import JSX from "react-native";
import DummyClass from "./util/dummy";
const DummyWrapper = () => {
return (DummyClass.getView());
};
export default DummyWrapper;
当我跑步时eslint，我会收到警告。
5:5 警告缺少函数 @typescript-eslint/explicit-module-boundary-types 的返回类型
所以，我需要返回一些东西。JSX.Element似乎足够合理，但这似乎不起作用。一方面，当我尝试返回 a 时JSX.Element，VSCode 无法解决它并假装它是any。而且，它会导致调用该函数的其他地方出错。
所以，这样做：
static getView() : JSX.Element {
和const DummyWrapper = () : JSX.Element => {
导致以下错误DummyCaller：
5:5 错误任何类型值的不安全返回 @typescript-eslint/no-unsafe-return
所以现在我不确定该怎么做。我尝试了其他一些事情，例如返回View、、typeof View（React.Component和typeof）以及其他一些事情。我还搞砸了 JSX 是从哪里导入的。如果我从 导入react，它似乎比从 导入它的效果更差react-native。同样在我的研究中，我发现最常见的问题是 React 和 React Native 类型已经过时，但据我所知，我使用的是最新版本。
