Fixed #

• Fold ranges now end at the start of the last line only when that line is a closing line (), ], } …). 0.1.0 applied this unconditionally, which hid only the newline before a non-closing last line and glued the neighbouring lines together: folding

  // first line
  // second line
  // third line
  

  produced // first line// third line. Content lines — the tail of a // comment block, a continued argument, an import group — are hidden whole again, exactly as upstream does, while folded closers stay on screen as before: parsers: [ ],, void method() { }, ScraperConfig();.

• The gutter now uses the code style's line height. CodeField._buildGutter() copied fontSize and fontFamily from the code style "for consistency with lines" but not height, so gutter rows fell back to the font's own metrics — 19 px against the code's 21 px at the default style. The two grids therefore drifted ~1.9 px on every line, reaching ~60 px by line 36 of a typical file. Because the fold chevron is centred in its gutter row it inherited that drift, so chevrons climbed above the line they labelled (over half a line off by line 9, worse further down). The gutter now starts on the code text's top edge with a row pitch equal to the rendered line height.

Added #

• gutter_alignment_test.dart pins the gutter/code grid invariant — top edge and row pitch — in both the folded and unfolded states.
• Comment-block regression tests pinning that non-closing blocks hide their last line whole, with no glued text.

First release of zuraffa_code_editor, a maintained fork of flutter_code_editor 0.3.5.

Changed #

• Folded blocks keep their closing line visible. Upstream hid a folded block through the end of its last line, so folding parsers: [ ... ] left a dangling parsers: [ with no matching ], — broken-looking code. The fold range now ends at the start of the block's last line, so the closing line stays on screen: parsers: [ ],, void method() { }, ScraperConfig();. Gutter line numbering, fold-toggle placement and the number of rendered rows are all unchanged — only the closing text is added back.
• Repackaged from flutter_code_editor to zuraffa_code_editor; all imports are now package:zuraffa_code_editor/zuraffa_code_editor.dart.
• Linting moved from total_lints to flutter_lints.
