Walkthrough

Korean translation README for Freezed was extensively rewritten to reflect Dart 3 and v3.0.0 migration: examples now use sealed classes and const factories, headings/navigation were restructured, and many code samples and notes were updated for pattern matching, unions, and JSON serialization.

Poem

I nibble docs with triple-tap feet,
Sealed dreams and consts so neat.
Patterns hop and unions play,
In Korean fields we shape the way.
Little rabbit inks the day. 🐇✨

⚠️ Potential issue | 🟡 Minor

Specify the fenced code block language.

markdownlint flags this block (MD040). Add console to match surrounding examples and keep lint green.

In resources/translations/ko_KR/README.md around lines 128 to 130, the fenced
code block is missing a language spec which triggers markdownlint MD040; update
the block opening fence from toconsole and keep the same command content
(preserve the line with "dart run build_runner watch -d") so the block matches
surrounding examples and the linter.

⚠️ Potential issue | 🟡 Minor

Use a proper heading instead of bold text.

MD036 complains because this line imitates a heading with bold text. Promote it to an actual heading (####) to satisfy the linter.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

(MD036, no-emphasis-as-heading)

🤖 Prompt for AI Agents

In resources/translations/ko_KR/README.md around lines 547 to 548, the line
"**null 고려사항**" is formatted as bold text that mimics a heading and triggers
MD036; replace the bold formatting with an actual markdown heading (e.g., prefix
the line with "#### " to make it a level-4 heading) so the linter accepts it and
keep the text unchanged otherwise.
