Because chatview >=1.0.0 depends on intl ^0.18.0 and mobile_app depends on intl ^0.17.0, chatview >=1.0.0 is forbidden – Flutter

I have this project which works fine when I had not added chatview: ^1.2.0+1. Now after adding it as a dependency, I get an error of

Because chatview >=1.0.0 depends on intl ^0.18.0 and mobile_app depends on intl ^0.17.0, chatview >=1.0.0 is forbidden.
So, because mobile_app depends on chatview ^1.2.0+1, version solving failed.
pub get failed

  "FLUTTER_ROOT": "/Users/samuel/flutter",
  "PUB_ENVIRONMENT": "vscode.dart-code:flutter_cli:get",
  "PUB_CACHE": "/Users/samuel/.pub-cache",
}
exit code: 1

Now i changed the version of my intl package to intl ^0.18.0 which I expected to work fine but I also got another error of

Because mobile_app depends on flutter_localizations from sdk which depends on intl 0.17.0, intl 0.17.0 is required.
So, because mobile_app depends on intl ^0.18.0, version solving failed.
