After webpack splits and loads the code, the react interface is not updated.
Post the code first

main.js

export default class extends React.Component { constructor(props) { super(props) this.state = { textview: undefined, text: 'text' } } _loadText() { if (!this.state.textview) require.ensure([], require => { const Text = require('./text').default; this.setState({ textview:  }) }) } render() { return ( 
 
Main
  this._loadText()}>load  this.setState({ text: 'change' })}>change {this.state.textview} 
 ) } }

text.js

export default class extends React.Component { render() { return ( 
{this.props.text}
 ) } }

After clicking load, the text control can be loaded and displayed.
But when clicking change to change the state, the text control will not be refreshed.
Print log this.state.text has changed.

I’ve been looking for it for a long time but I still don’t know what the problem is. Please ask God T.T
Thank you
