React Leaflet问题：如何正确配置ReactLeaflet矢量形状pathOptions？

Question

我将矢量形状引入到我的 React Leaflet 项目中，但我无法应用 pathOptions。路径选项似乎不适用于矢量形状。

我正在尝试复制工作正常的文档示例... https://react-leaflet.js.org/docs/example-panes/

...但是将完全相同的代码结构应用于沙箱不起作用： https://codesandbox.io/s/react-leaflet-pathoptions-not-working-n3env?file=/src/index.js

代码摘录

  render() {
    return (
      <div>
        <Map center={this.state.center} zoom={this.state.zoom}>
          <TileLayer
            attribution='&amp;copy <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
            url="https://{s}.tile.osm.org/{z}/{x}/{y}.png"
          />
          <Pane name="orange-circle" style={{ zIndex: 500 }}>
            {/* note that pathoptions are being ignored */}
            <Circle
              center={this.state.center}
              radius={1000}
              pathOptions={{fillOpacity: 1, color: "orange"}}
            />
          </Pane>
        </Map>
      </div>
    );
  }
}

结果：未应用路径选项。

非常感谢任何关于我可能遗漏的东西的帮助或建议，或者一个可用的沙箱。

pathOptions 在新的 MapContainer 组件中的 react-leaflet 3 中实现。

react-leaflet 3.1 - pathOptions w/ MapContainer 注意 react-leaflet 3.1.0 的依赖性变化

使用 react-leaflet 2.8 的解决方法是将选项声明为一个对象，然后将其传播到组件中以将每个选项作为其自己的 prop 传递。

react-leaflet 2.8 - pathOptions work-around

const { Map, TileLayer, Pane, Path, Circle } = window.ReactLeaflet;

class App extends React.Component {
  state = {
    center: [51.505, -0.091],
    zoom: 13
  };
  

  render() {
  
  const pathOptions= {fillOpacity: 1, color: "orange"};
  
    return (
      <div>
        <Map center={this.state.center} zoom={this.state.zoom}>
          <TileLayer
            attribution='&amp;copy <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
            url="https://{s}.tile.osm.org/{z}/{x}/{y}.png"
          />
          <Pane name="orange-circle" style={{ zIndex: 500 }}>
            {/* note that pathoptions are being ignored */}
            <Circle
              center={this.state.center}
              radius={1000}
             {...pathOptions}
            />
          </Pane>
        </Map>
      </div>
    );
  }
}

ReactDOM.render(<App />, document.getElementById('root'));

.leaflet-container {
  height: 100vh;
  width: 100vw;
}
