[FEATURE REQUEST]: display package's dependencies' versions

I am trying to use [`flutter_native_splash`](https://pub.dev/packages/flutter_native_splash) (at the time of writing the latest version is `2.2.17`) and [`flutter_launcher_icons`](https://pub.dev/packages/flutter_launcher_icons) (at the time of writing the latest version is `0.11.0`) at the same time in my app.

The problem I am facing is that `flutter_native_splash`'s latest version depends on `image ^4.0.10` while `flutter_launcher_icons`'s latest version depends on `image ^3.0.2`.

My strategy to fixing this was to go to `pub.dev` and find the version of `flutter_native_splash` that depends on `image ^3.0.2`, but pub.dev does not display the version of dependencies of the selected package version.

Adding a package version next to each of the dependencies will enable users to resolve such version incompatibilities much quicker.
