If I format a file with the following content, a new line is added before the comment.

void main() {
  print('Printing');
}
// Something.

Results in:

void main() {
  print('Printing');
}

// Something.

This doesn't happen for comments after earlier blocks. For example, the following doesn't change (as I'd expect).

void main() {
  f();
}
// Something.

void f() {
  print('Printing');
}
