Problem
I'm maintaining a package that supports both "plain" dart native and flutter (ios, android) and wanted to update pubspec to the new format including "platforms".
After adding platforms key to the pubspec.yaml, pub publish prints the following error (see this PR #2265):
Package validation found the following error:
* pubspec.yaml allows Flutter SDK version 1.9.x, which does not support the flutter.plugin.platforms key.
Please consider increasing the Flutter SDK requirement to ^1.10.0 (environment.sdk.flutter)
OK, so I add flutter to the environment and pub publish works now:
environment:
sdk: ">=2.6.0 <3.0.0"
flutter: ">=1.12.0 <2.0.0"
But this change has dropped the non-flutter (plain dart) support so dart-only packages depending on this lib are broken:
$ pub get
Resolving dependencies...
Because dart_only_app depends on objectbox_flutter_libs from path which requires the Flutter SDK, version solving failed.
Flutter users should run `flutter pub get` instead of `pub get`.
Proposed solution
Change the pub publish error to warning so the package with the platforms key can be publish even if it doesn't specify the dependency on flutter explicitly.
