I create data class X (...) then I use X.toString and now I want to convert that string back to data class X object what shall I do? Is there a Kotlin way to done this?

[Joffrey]

toString() is not meant for serialization, it is meant to help for printing/debugging/logging etc. If you want to serialize/deserialize, you should probably use more suited formats

I see thank you

[ephemient]

in general the toString() cannot be inverted. for example,

data class X(val a: String, val b: String)
val x1 = X(a = "a, b=b", b = "b")
val x2 = X(a = "a", b = "b, b=b")
x1 != x2
x1.toString() == x2.toString()

I found Kotlinx.Serialization is that a key for my problem?

[Rein T]

yes, and if you want serialize to a string, json is probably the format to go with
