val date and val source?

[oianmol]

i used var

[oianmol]

abstract class Message {
abstract var date: Long;
abstract var source: MessageSource
abstract var type: MessageType
}

data class TextMessage(
override var date: Long = 0L,
override var source: MessageSource = MessageSource.BOT,
override var type: MessageType = MessageType.TEXT,
var text: String
) : Message()

[gildor]

TextMessage(text = "my text") and should work already with your code

[gildor]

or just make first constructor argument and you can write TextMessage("my text") instead

[oianmol]

have you tried ? it doesn't work. it asked me to add all the parameteres to the args

[oianmol]

can you paste the way you have written your constructor

[gildor]

Just copied your code and the first way works

[oianmol]

thanks buddy it worked TextMessage(text = "my text")

[gildor]

second should work if text will be the first argument:

data class TextMessage(
        var text: String,
        override var date: Long = 0L,
        override var source: MessageSource = MessageSource.BOT,
        override var type: MessageType = MessageType.TEXT
) : Message()

Kotlin doesn’t allow to mix optional and non-optional arguments without explicit argument name, so better to put args with default values after other args
