How to credit packages used in a commercial flutter project?

I have used many libraries from the pub dev site in my flutter project and i notices many of them use the bsd, mit or apache 2.0 licence. I want to release this app in the future and have read that you should make sure the library licences are available in the source code. Is this correct?

If I just include them in my pubspec.yaml does this already do this?

If I need to include a reference to all the libraries i use in my project and there licences is there a way to auto generate such a thing in flutter?

I have been reading online and there seems to be a few methods in android to do this e.g.

The produces the following output.

Could anybody help me with this?

Thanks a lot 🙂
