推荐答案
要在组件中正确访问DirestionsRendererOptions,您需要使用options
prop,如下所示:
In order access DirestionsRendererOptions right in component, you need to use options
prop, like that:
<DirectionsRenderer
directions={props.directions}
options={{
polylineOptions: {
strokeOpacity: 0.5,
strokeColor: '#FF0000',
},
}}
/>
请参阅文档,以了解有关您有权使用的选项的更多信息: https://developers.google.com/maps/documentation/javascript/reference/3.exp/directions#DirectionsRendererOptions
Please see the documentation to find out more about the options you have access to: https://developers.google.com/maps/documentation/javascript/reference/3.exp/directions#DirectionsRendererOptions
