    // core of event state
    implementation 'com.github.utsmannn.diana-state-handle:core:1.0.3'

    // adapter for retrofit
    implementation 'com.github.utsmannn.diana-state-handle:adapter:1.0.3'

    // susbcriber interface (optional)

Retrofit Adapter

For the use adapter, return parameter must be StateEventResponse and set adapter to StateEventAdapterFactory.create()

interface WebServices {

    @GET(EndPoint.GET_USER)
    suspend fun getList(): StateEventResponse<UserResponses>
    
    companion object {
        fun build(): WebServices {
            return Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(StateEventAdapterFactory.create()) // use this adapter
                .client(okHttpClient)
                .build()
                .create(WebServices::class.java)
        }
    }
}

Handler

class UseCase(val webServices: WebServices) {
    suspend fun getList() {
        when (val state = webServices.getList().eventFlow()) {
            is StateEvent.Idle -> { RenderIdle() }
            is StateEvent.Loading -> { RenderLoading() }
            is StateEvent.Failure -> { RenderFailure(state.exception) }
            is StateEvent.Success -> { RenderSuccess(state.data) }
        }
    }
}
