Dart ignore dependency? - dart

Question

How can I ignore a dependency in a project?
My project setting is:
Project A: depends on Angular2 & depends on Foundation
Project Foundation: depends on Redstone_mapper_mongo
The problem is I want to use angular2 in my Project A which depends on my Project Foundation. However the Project Foundation uses the redstone mapper mongo but angular2 and redstone mapper mongo dont work together.
Question:
So in my foundation is something like this. Can I just ignore these #Field(), #NotEmpty and the import somehow in Project A? So that angular works just fine in Project A? Therefore redstone mapper mongo shouldn't be loaded in Project A. But how can I do this?
import 'package:redstone_mapper/mapper.dart';
class Address {
#Field()
#NotEmpty()
String street;
#Field()
#NotEmpty()
String city;
}
[Update]
I have these dependencies in my project A now. I added
code_transformers: ^0.5.1
Project A pubspec.yaml
dependencies:
angular: "^4.0.0+2"
angular_forms: "^1.0.0"
foundation:
path: ../foundation
dependency_overrides:
code_transformers: ^0.5.1
dev_dependencies:
angular_test: ^1.0.0
browser: ^0.10.0
dart_to_js_script_rewriter: ^1.0.1
test: ^0.12.30
transformers:
- angular:
entry_points:
- web/main.dart
- test/**_test.dart
- test/pub_serve:
$include: test/**_test.dart
- dart_to_js_script_rewriter
Fondation pubspec.yaml
dependencies:
intl: "^0.15.2"
http: "^0.11.3+16"
great_circle_distance: "^1.0.1"

jaguar_serializer: "^0.5.1"
dev_dependencies:
browser: "^0.10.0+2"
dart_to_js_script_rewriter: "^1.0.3"

Answer 1

In the Angular project adding
dependency_overrides:
code_transformers: ^0.5.1
analyzer: 0.30.0+4
should fix it

Answer 2

In the fondation project I added a local dependency of my own empty implementation
redstone_mapper_mongo:
path: ../redstone_mapper_mongo
And in this empty implementation the Field and NotEmpty annotations are just declared.
library redstone_mapper;
class Field {
const Field();
}
class NotEmpty {
const NotEmpty();
}
Like this it is possible now that Project A uses the local variant and Angular2 without any issues. And without creating a second world of model objects.
I used the dependency_overrides in my project B with the real version of redstone_mapper_mongo and so the annotations #Field and #Empty are using the real implementation of the redstone_mapper_mongo. And everything works fine now.
dependency_overrides:
redstone_mapper_mongo: "0.2.0-beta.1"
