leading_newlines_in_multiline_strings

Start multiline strings with a newline.

This rule is available as of Dart 2.8.

This rule has a quick fix available.

Multiline strings are easier to read when they start with a newline (a newline starting a multiline string is ignored).

BAD:

var s1 = '''{
  "a": 1,
  "b": 2
}''';

GOOD:

var s1 = '''
{
  "a": 1,
  "b": 2
}''';

var s2 = '''This one-liner multiline string is ok. It usually allows to escape both ' and " in the string.''';

To enable the leading_newlines_in_multiline_strings rule, add leading_newlines_in_multiline_strings under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - leading_newlines_in_multiline_strings
