Answer 1

You can use similar in Kotlin class

class InventoryMoveRequest {
    @SerializedName("userEntryStartDate")
    @Expose
    var userEntryStartDate: String? = null
    @SerializedName("userEntryEndDate")
    @Expose
    var userEntryEndDate: String? = null
    @SerializedName("location")
    @Expose
    var location: Location? = null
    @SerializedName("containers")
    @Expose
    var containers: Containers? = null
}

And also for nested class you can use same like if there is nested object. Just provide Serialize name for the Class.

@Entity(tableName = "location")
class Location {

    @SerializedName("rows")
    var rows: List? = null
    @SerializedName("totalRows")
    var totalRows: Long? = null

}

so if get response from the server each key will map with JOSN.

Alos, convert List to JSON:

val gson = Gson()
val json = gson.toJson(topic)

ndroid convert from JSON to Object:

val json = getJson()
val topic = gson.fromJson(json, Topic::class.java)
