flutter - 错误: Couldn't resolve the package 'gql_code_builder' from repository layer

Question

我创建了一个 data_provider 包和一个存储库包。如果我在 data_provider 中运行 main.dart，一切正常，并且我得到了获取的数据。但是如果我想从存储库层获取数据，我会收到此错误:

lib/example/main.dart: Warning: Interpreting this as package URI, 'package:profile_repository/example/main.dart'.
lib/example/main.dart:1

  static Serializer<GJSON> get serializer => _i2.DefaultScalarSerializer<GJSON>(

main.dart(存储库层)

// ignore_for_file: avoid_print, avoid_void_async, unnecessary_lambdas,

import 'package:data_provider/data_provider.dart';
import 'package:ferry/ferry.dart';
import 'package:get_it/get_it.dart';
import 'package:profile_repository/profile_repository.dart';

void main() async {
  final client = await initClient();
  GetIt.I.registerLazySingleton<Client>(() => client);

  try {
    final profiles = await ProfileRepository().getProfiles();
    print('Profiles: $profiles');
  } on Exception catch (e) {
    print(e);
  }
}

配置文件存储库:

import 'package:data_provider/data_provider.dart';

/// Thrown when an error occurs while looking up for profiles.
class ProfilesException implements Exception {}

/// {@template profile_repository}
/// Profiles from different categories fetched
/// {@endtemplate}
class ProfileRepository {
  /// {@macro profile_repository}
  ProfileRepository({ProfileService? profileService})
      : _profileService = profileService ?? ProfileService();

  final ProfileService _profileService;

  /// Returns a list of all club and players profiles.
  ///
  /// Throws a [ProfilesException] if an error occurs.
  Future<List<GGetProfilesData_profiles>?> getProfiles() async {
    try {
      final profiles = await _profileService.getProfiles();
      return profiles;
    } on Exception {
      throw ProfilesException();
    }
  }
}

profile_service(数据层):

// ignore_for_file: avoid_print

import 'package:built_collection/built_collection.dart';
import 'package:data_provider/data_provider.dart';
import 'package:ferry/ferry.dart';
import 'package:get_it/get_it.dart';

class ProfileService {
  final client = GetIt.I<Client>();

  Future<List<GGetProfilesData_profiles>?> getProfiles() async {
    try {
      final profilesReq = GGetProfilesReq();
      BuiltList<GGetProfilesData_profiles>? result;

      final value = await client.request(profilesReq).first;

      RequestHelper.checkError(value);

      if (value.data != null && value.data!.profiles != null) {
        result = value.data!.profiles;
      }

      return result?.toList();
    } on DataProviderGraphqlErrorException catch (e) {
      print(e.toString());
    } on DataProviderLinkException catch (e) {
      print(e.toString());
    }
    return List.empty();
  }
}

main.dart(data_provider，什么有效!)

// ignore_for_file: avoid_print, avoid_void_async, unnecessary_lambdas,

import 'package:data_provider/data_provider.dart';
import 'package:ferry/ferry.dart';
import 'package:get_it/get_it.dart';

void main() async {
  final client = await initClient();
  GetIt.I.registerLazySingleton<Client>(() => client);

  try {
    final profiles = await ProfileService().getProfiles();
    print('Profiles: $profiles');
  } on Exception catch (e) {
    print(e);
  }
}

编辑:看来导入实现看起来不正确。但是文件已经生成了...

我已经找到解决办法了。虽然不是完美的，但它确实有效。

@knaecke 引导我找到答案。您可以在主库上的 pubspec.yaml 的“dependency:”部分显式添加 gql_code_builder(而不是真正使用它的包)。

这很丑陋而且很奇怪，但是，它确实有效......
