it might be the editor doing this kind of indentation, I think this should just
be all in 1 or 2 lines. Any of these seem better:
static const List<String> _balloonBits = const[
    'balloon_pieces_a', 'balloon_pieces_b', 'balloon_pieces_c',
'balloon_pieces_d'];

static const List<String> _balloonBits = const[
    'balloon_pieces_a',
    'balloon_pieces_b',
    'balloon_pieces_c',
    'balloon_pieces_d',
  ];
