@sachins-geekyants Why was it OK to merge the PR even though the melos-bootstrap check failed?

@gkc The deps conflict shown here is not happening when we go a flutter pub get.

OK ... would be good to know why the melos-bootstrap check is failing though

melos-bootstrap issue was reproduced locally in at_contacts_flutter package because of at_common conflict between onboarding and contact_flutter package.

In next PR, these conflicts will be reolved.
