bootstrap does not discriminate between dependencies and dev_dependencies

[iapicca]

Is there an existing issue for this?

• I have searched the existing issues.

Version

2.7.1

Description

melos bootstrap creates incompatibility between an application (in the example flutter_app)
and a package (test_package)
regardless the fact that said package is not used in the application itself
and only present in the dev_dependencies of the imported package

Steps to reproduce

1. setup monorepo

steps

• create folders as below

mkdir test_folder
mkdir test_folder/packages
mkdir test_folder/examples

• add to test_folder a melos.yaml file with the content below

name: test_folder
packages:
  - examples/**
  - packages/**
ignore:
  - packages/**/example

2. setup packages

steps

• create the packages as below

cd test_folder/packages
dart create -t package test_package
dart create -t package feature_package

• replace test_package's pubspec.yaml with the following

name: test_package
description: none
publish_to: 'none'

environment:
  sdk: '>=2.18.1 <3.0.0'

dependencies:
  test: ^1.21.6

dev_dependencies:
  lints: ^2.0.0

• replace feature_package's pubspec.yaml with the following

name: feature_package
description: none
version: 1.0.0
publish_to: 'none'

environment:
  sdk: '>=2.18.1 <3.0.0'

dev_dependencies:
  lints: ^2.0.0
  test: ^1.21.6
  test_package:
    path: ../../packages/test_package

3. setup examples

steps

• create the following packages

cd ../examples
flutter create flutter_app

• replace flutter_app's pubspec.yaml with the following

name: flutter_app
description: A new Flutter project.
publish_to: 'none'
version: 1.0.0+1

environment:
  sdk: '>=2.18.1 <3.0.0'

dependencies:
  flutter:
    sdk: flutter
  feature_package:
    path: ../../packages/feature_package

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_lints: ^2.0.1

flutter:
  uses-material-design: true

4. run flutter pub get/ dart pub get everywhere

cd packages/test_package && dart pub get
cd ../feature_package && dart pub get
cd ../../examples/flutter_app && flutter pub get

5 run melos bootstrap

Expected behavior

as pub get is successful I'd expect melos bootstrap to succeed as well

Actual behavior

melos boot throws the following

melos bootstrap
  └> /Volumes/ROG/dev/test_folder

Running "flutter pub get" in workspace packages...
  - flutter_app
    └> examples/flutter_app
       └> Failed to install.

Running "flutter pub get" in flutter_app...
Because every version of test_package from path depends on test ^1.21.6 which depends on test_api 0.4.14, every version of test_package from path requires test_api 0.4.14.
And because every version of flutter_test from sdk depends on test_api 0.4.12, test_package from path is incompatible with flutter_test from sdk.
So, because flutter_app depends on both flutter_test from sdk and test_package from path, version solving failed.
pub get failed (1; So, because flutter_app depends on both flutter_test from sdk and test_package from path, version solving failed.)
BootstrapException: Failed to install.: flutter_app at /Volumes/ROG/dev/test_folder/examples/flutter_app.
