I have simple model and I want to use user profil image and name, but it is throw an error like "Unreachable code" for
participants.find { it.id != userId }!!.profilePicture
and
participants.find { it.id != userId }!!.username
class Talk(
val participantsId: ArrayList<String>
): BaseModel(), Serializable {
var participants = ArrayList<Data>()
val messages = ArrayList<Message>()
fun getProfilePicture(userId: String) {
return
participants.find { it.id != userId }!!.profilePicture
}
fun getTalkName(userId: String) {
return
participants.find { it.id != userId }!!.username
}
}
any idea?
CodePudding user response:
Since in Kotlin lines don't need to end with a column (;
), return followed by a new line is interpreted as a return with no return value (equivalent to return;
in Java).
You just need to remove the new lines after the return
s and change the return type of your functions with the actual types you are returning. e.g.: (I've assumed String
a return type)
fun getTalkName(userId: String): String {
return participants.find { it.id != userId }!!.username
}
