Hiding the implementation files is best practice according to Dart
organising a library package, https://bit.ly/3fA23Yz. It also helps
us to know which files we can change without worrying about breaking
changes.
The PR is not a breaking change, because the classes can still be
imported via the old files. In the next breaking change update, these
old files can then be removed.
No functionality was changed in the PR.
Declaring variables as final when possible is a good practice
because it helps avoid accidental reassignments and allows the
compiler to do optimizations.
