If you want to use Gson with kotlin extension

Extension function

inline fun <reified T : Any> String.toDataClass(): T =
    Gson().fromJson(this, T::class.java)

inline fun <reified T : Any> T.toJsonString(): String =
    Gson().toJson(this)

Use to convert string and visaversa

// to get String from DataClass object
val jsonString: String = note.toJsonString()

// to get DataClass object from String
val note = jsonString.toDataClass<Note>()
