How convert Object String to Data Class in kotlin

I want to convert below .tostring to data class how to convert?

InstrumentResponse(AGM=false, AllOrNone=true, Bonus=true, Dividend=true, EGM=false, AuctionDetailInfo=AuctionDetailInfo(AuctionNumber=0, AuctionStatus=0, InitiatorType=0)

What I am trying to do to pass data class though bundle from one fragment to another but doing with bundle.putString how to convert this again to a data class ?

Is there a better way to achieve ? or how to convert dataClass.toString to Data class ?

To pass data class between activities, don't use toString. Instead, use putParcelable. A parcelable is a custom serialization format for Android. See the official documentation (with examples) here.

If you don't want to dig into Parcelable implementation details, you can use the kotlin experimental features.

Starting from Kotlin 1.1.4, Android Extensions plugin provides Parcelable implementation generator as an experimental feature.

In short, add 

androidExtensions {
    experimental = true
}

to your build.gradle, then use the @Parcelize annotation in your data class and make it inherit from Parcelable:

import kotlinx.android.parcel.Parcelize

@Parcelize
class InstrumentResponse(...): Parcelable

You should just use @Parcelize.

Add 

androidExtensions {
    experimental = true
}

to you build.gradle.

Then add the annotation to you class

@Parcelize
data class InstrumentResponse(...)

Then put the value directly into the Bundle

bundle.putParcelable(key, instrumentReponse)

To retrieve the value, call

val instrumentReponse = bundle.getParcelable<InstrumentResponse>(key)
