This check is tagged
:formatter
This means you can disable this check when also using Elixir's formatter.
This check has a base priority of low
and works with any version of Elixir.
Explanation
Files should end in a trailing blank line.
This is mostly for historical reasons: every text file should end with a \n,
or newline since this acts as eol
or the end of the line character.

Most text editors ensure this "final newline" automatically.
Like all Readability
issues, this one is not a technical concern.
But you can improve the odds of others reading and liking your code by making
it easier to follow.
