遵循教程和代码看起来相同,但仍然会出错: “ 126:20-30'react-spring'不包含名为'Transition'的导出。” ...我阅读了react spring的文档以获取过渡效果,并尝试了更改导入将我的代码重新定义为文档所说的内容,但仍然没有。
import React, { Component, Fragment, createContext } from 'react';
import { Transition } from 'react-spring';
import logo from './logo.svg';
import './App.css';
import { Toggle } from 'Utilities';
import { Modal } from 'Elements';
import User from './User';
import UserProvider from './UserProvider';
class App extends Component {
render() {
return (
<UserProvider>
<div className="App">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h1 className="App-title">Welcome to React</h1>
</header>
<User />
<section>
<Toggle>
{({ on, toggle }) => (
<Fragment>
<button onClick={toggle}>Show / Hide</button>
<Transition
from={{ opacity: 0 }}
enter={{ opacity: 1 }}
>
{on && <Header />}
</Transition>
</Fragment>
)}
</Toggle>
</section>
<Toggle>
{({ on, toggle }) => (
<Fragment>
<button onClick={toggle}>Login</button>
<Modal on={on} toggle={toggle}>
<h1>Still what's up this is Gabriel</h1>
</Modal>
</Fragment>
)}
</Toggle>

我的研究更加详细,已经解决了。
import { Transition } from 'react-spring/renderprops'
<Transition items={on} from={{ opacity: 0 }} enter={{ opacity: 1 }}>
{on => on && Header}
</Transition>

您将使用的与react-spring
有关的任何内容
'renderprops
'
例如:
Import { Transition } from 'react-spring/renderprops'
