如何在react-kova中获得像scaleX这样的图像属性？

import React from 'react';
import { Stage, Layer, Image, Transformer } from 'react-konva';

class App extends React.Component {
  state = {
    selectedImage: null,
  };

  handleSelectImage = (image) => {
    this.setState({ selectedImage: image });
  };

  render() {
    return (
      <Stage width={window.innerWidth} height={window.innerHeight}>
        <Layer>
          <Image
            image={imageObj}
            onClick={() => this.handleSelectImage(imageObj)}
          />
          {this.state.selectedImage && (
            <Transformer
              node={this.state.selectedImage}
              // 可以通过getAttr方法获取scaleX属性
              scaleX={this.state.selectedImage.getAttr('scaleX')}
            />
          )}
        </Layer>
      </Stage>
    );
  }
}

export default App;
