package:dart_style v3.1.3

• No longer format imports with configurations and a prefix in the wrong order.
  The parser used to accept this without error even though it violated the
  language spec. The parser is being fixed, so the formatter will no longer
  accept or format code like:

  import 'foo.dart' as prefix if (cond) 'bar.dart';

• Don't force a space between ? and . if a null-aware element contains a
  dot shorthand.
• Require analyzer: '>=8.2.0 <10.0.0'.
• Require args: ^2.5.0.
• Require sdk: ^3.9.0.

Bug fixes

• Respect @dart= version comments when determining which >3.7 style to apply.
  The formatter correctly used those comments to switch between the old short
  and new tall style, but ignored them for language versioned style rule changes
  after 3.7. Now the language version of the file is consistently respected for
  all style rules (#1762).
