Android平台Dart/Flutter发布模式堆栈追踪错误原因排查

调试模式下调用Trace.current()可正常工作，但发布模式下调用该方法得到的堆栈追踪结果存在明显错误（对应代码路径不可能存在）。多数甚至全部发布模式下的堆栈追踪都存在这类问题，其中会有一到两个函数调用信息错误。

调试模式堆栈追踪（正确显示GlobalChannelProxyService.createChannel调用） #

package:poly_scrabble_mobile/room_service/room_service.dart 52:36              RoomService._getCurrentFunctionName
package:poly_scrabble_mobile/room_service/room_service.dart 134:25             RoomService.callServer
package:poly_scrabble_mobile/services/global_channel_proxy_service.dart 17:33  GlobalChannelProxyService.createChannel
package:poly_scrabble_mobile/main_page/chat/create_channel_dialog.dart 14:10   CreateChannelDialog.submit
package:poly_scrabble_mobile/main_page/chat/create_channel_dialog.dart 44:17   CreateChannelDialog.build.<fn>
...

发布模式堆栈追踪（错误显示未被调用的GameServiceProxy.executePlace） #

package:poly_scrabble_mobile/room_service/room_service.dart 52             RoomService._getCurrentFunctionName
package:poly_scrabble_mobile/room_service/room_service.dart 134            RoomService.callServer
package:poly_scrabble_mobile/services/game_proxy_service.dart 84           GameServiceProxy.executePlace
package:poly_scrabble_mobile/main_page/chat/create_channel_dialog.dart 16  CreateChannelDialog.submit.<fn>

注意：GameServiceProxy.executePlace在应用中从未被调用过，但它是一个异步函数，这可能与问题相关。

注释GameServiceProxy.executePlace后的发布模式堆栈追踪（仍存在错误路径） #

package:poly_scrabble_mobile/room_service/room_service.dart 52              RoomService._getCurrentFunctionName
package:poly_scrabble_mobile/room_service/room_service.dart 111             RoomService.reflectProp
package:poly_scrabble_mobile/services/self_user_proxy_service.dart 12       SelfUserProxyService.user
package:poly_scrabble_mobile/room_service/room_service.dart 165             RoomService._callServerBase
package:poly_scrabble_mobile/room_service/room_service.dart 148             RoomService.callServer
package:poly_scrabble_mobile/services/global_channel_proxy_service.dart 17  GlobalChannelProxyService.createChannel
package:poly_scrabble_mobile/main_page/chat/create_channel_dialog.dart 14   CreateChannelDialog.submit
package:poly_scrabble_mobile/main_page/chat/create_channel_dialog.dart 33   CreateChannelDialog.build.<fn>
...

注意：其中的SelfUserProxyService.user同样属于不可能的调用路径，看起来像是两个堆栈追踪被混淆了。
