protobuf dart 编译器生成的代码有很多错误（方法未找到或不是类型）
protobuf dart compiler generates code with lots of errors (Method not found or Is not a type)
我将一些 protobuf 代码编译为 C++，它运行良好，但对于 Dart（使用截至今天第 6 天的最新提交），我在尝试使用生成的代码编译我的项目时遇到很多错误。
例如，这个文件：
syntax = "proto3";
import "stream_setup.proto";
import "uuid.proto";
package message;
message Collection {
UUID uuid = 1;
string name = 2;
//Each entry should represent the order in which the StreamSetup appears
//in the collection. Since it's a map it can't have repeated entries
map<sint32, StreamSetup> streams = 3;
}

我不知道发生了什么。它应该可以工作，因为我没有修改生成的文件中的任何内容，我只是将它们放在一个包中并加载到我的项目中。
我解决了我的问题。
我必须添加那些库
将 .proto 转换为 dart
https://pub.dev/packages/protoc_plugin
转换后显示很多错误并添加了这些库。
fixnum: ^1.0.0
protobuf: ^2.0.0
添加后仍然显示一些错误，但现在导入无效
import '../../../DartFile.pbenum.dart';
export '../../../DartFile.pbenum.dart';
我将手动生成的文件更改为，因为它们在同一个文件夹中。我不知道为什么会像上面那样生成
