Description

When I use OpenApi Generator (5.0.1) to generate models for Flutter app it fails during app building with error:

Because every version of flutter_localizations from sdk depends on intl 0.17.0 and every version of core_design from path depends on intl ^0.16.1, flutter_localizations from sdk is incompatible with core_design from path.

So, because login depends on both core_design from path and flutter_localizations any from sdk, version solving failed.

This started to happen after upgrade to Flutter 2.0

openapi-generator version

I tested 5.0.1 and 5.0.0-beta2

Generation Details

java -jar openapi-generator-cli.jar generate -i ${OPENAPI_DRIVER_SPEC_FILE} -g dart -c open-generator-config.yaml --enable-post-process-file --global-property models,supportingFiles

config: # Config options for the dart-hhtp generator pubName: model_generator pubVersion: 0.0.1 pubDescription: <project name>

Steps to reproduce

Generate models, run flutter pub get.

Suggest a fix

Upgrade intl package version to 0.17.0+
