protobuf dart compiler generates code with lots of errors (Method not found or Is not a type)
I compiled some protobuf code to C++ and it worked fine, but for Dart (using the latest commit as of today day 6), I'm getting lots of errors when trying to compile my project with generated code.
For example, this file:
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;
}
generates this file: https://pastebin.com/HK70SfGv, which when compiled in my Dart project, gives:

I don't have idea about what's happening. It should work as I didn't modify anything in the generated files, I've simply put them inside a package and loaded into my project.

I solved mine.
I have to add those libraries
for convertin .proto to dart
https://pub.dev/packages/protoc_plugin
after converting it showed a lot of errors and added these libraries.
fixnum: ^1.0.0
protobuf: ^2.0.0
After added still it showed some errors but now imports were invalid
import '../../../DartFile.pbenum.dart';
export '../../../DartFile.pbenum.dart';
I changed manually generated files too because they were on the same folder. somehow it generated in wrong path.
import 'DartFile.pbenum.dart';
export 'DartFile.pbenum.dart';
