Android Realm: Cannot modify managed objects outside of a write transaction.

 java.lang.IllegalStateException: Cannot modify managed objects outside of a write transaction.

日誌如上，解決方案是在代碼中Realm處理的部分套一層處理“ Realm.Transaction { ”

      Realm.Transaction {
                val existUserInfoBean = userCase.findUserInfoByUserId(pref?.userId!!)
                if (existUserInfoBean != null) {
                    existUserInfoBean.currentImageQuality = true
                    userCase.updateUserInfo(existUserInfoBean)
                }
            }
