一旦启用了proguard，我就无法在gson库的帮助下转换POJO类中的JSON字符串，我得到的是空值，但在禁用proguard时，它工作正常

Log.d(TAG, "JSON: ${StringUtils.data}")
    try {
       val quickReplyButton = Gson().fromJson(StringUtils.data, QuickReplyButton::class.java)
        Log.e(TAG, "quickReplyButtondata:" +quickReplyButton)
    }
    catch (e: Exception){
        e.printStackTrace()
    }

波若级

package com.mypackage.sdk.data.model

    data class QuickReplyButton(
        val nodes: List<Node>,
        val showMessageText: Boolean,
        val transitions: List<Transition>,
        val widgetAction: String,
        val widgetType: String,
        val widgetView: String
    )

    data class Node(
        val controls: Controls,
        val id: String
    )

    data class Transition(
        val from: String,
        val name: String,
        val to: To,
        val trigger: String
    )

    data class Controls(
        val `0`: X0
    )

    data class X0(
        val event: Event,
        val id: String,
        val text: List<String>,
        val type: String,
        val values: List<String>
    )

    data class Context(
        val border: String,
        val color: String,
        val textColor: String,
        val textStyle: String
    )

    data class Event(
        val name: String
    )

    data class To(
        val sendMessage: SendMessage
    )

    data class SendMessage(
        val displayText: String,
        val nvaaId: String,
        val nvaaType: String,
        val selected: String,
        val selectedText: String,
        val selectedValue: String
    )

# removes such information by default, so configure it to keep all of it.
