There is an object inside the variable 'near_earth_object'. That date is supposed to be an input from the user.

Since it is dynamic, how do I create a data class of that object? I can create the object 'near_earch_object' as a list, but of objects with those variables inside the date.

But how do I get the date then?

Basically, can someone explain How to create data class of this JSON.

CodePudding user response：

Since you don't know the dates beforehand, you can't create properties for them, you will have to use a map here.

data class ApiResponse(
    @SerializedName("element_count")
    val elementCount: Int,
    @SerializedName("near_earth_objects")
    val nearEarthObjects: Map<String, List<NearEarthObject>>
)

data class NearEarthObject(
    val id: String,
    val name: String,
    ...
)
