反应原生地图超级集群添加我的标记

Question

我成功地使用react-native-maps-super-cluster运行了网站提供的代码。

但是我不知道如何将我的自定义标记添加到代码中。

如何添加我的自定义标记。

当我添加标记时，它没有聚集。

标记数量超过1000+。

依赖项是

"dependencies": {
"geolocation": "^0.2.0",
"react": "16.9.0",
"react-native": "0.61.5",
"react-native-geolocation-service": "^3.1.0",
"react-native-maps": "0.26.1",
"react-native-maps-super-cluster": "^1.6.0",
},

波纹管是当前代码。

我认为您的问题是您在mapview组件中静态定义每个标记。您传递给 renderMarker 属性的函数将为提供给 Mapview 的数据属性的每个标记渲染一个标记。这将允许包动态聚类标记数组。
