这是我的地图(地图列表).

this is my map(list of map).

Map<String, dynamic> toMap() => { "latitude": latitude, "longitude": longitude, "accuracy": accuracy, "altitude": altitude, "speed": speed, "speed_accuracy": speedAccuracy, "heading": heading, "time": time, };

有什么解决方案可以将这种数组存储在Firestore上吗?

Is there any solution to store this kind of array on firestore?

推荐答案

在Firestore中，不能超过文档的最大大小.

It's not possible to exceed the max size of a document in Firestore.

您应该做的是将每一项数据拆分到自己的文档中，可能在嵌套在主文档下的子集合中.

What you should do instead is split each item of data into its own document, probably in a subcollection nested under a primary document.
