请说明我是否可以对此进行任何改进E / flutter（29031）：[错误：flutter / lib / ui / ui_dart_state.cc（148）]未处理的异常：未知类型：float64E / flutter（29031）：＃0 getType（软件包：eosdart / src / serialize.dart：1149：3）E / flutter（29031）：＃1 getTypesFromAbi。 （软件包：eosdart / src / serialize.dart：1194：20）E / flutter（29031）：＃2 CastMap.forEach。 （dart：_internal / cast.dart：286：8）E / flutter（29031）：＃3 __InternalLinkedHashMap＆_HashVMBase＆MapMixin＆_LinkedHashMapMixin.forEach（dart：collection-patch / compact_hash.dart：367：8）
之所以出现此错误，是因为Eosdart pacakge的序列化文件中没有float32和float64。在eosdart存储库中，有一个关于float32-和float64-串行化的开放git问题和一个pull请求，
请参见：Issue和Pull-Request
而且还有一个与Eosdart相同的新库来解决Float类型序列化问题，因此您也可以通过此程序包snaxdart
