Flutter Upgrade is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/flutter-upgrade/ and loads when your prompt matches the skill's trigger.
The Flutter Upgrade skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It is part of the open ClaudSkills registry, a community-curated catalog of 56,000+ capabilities you can install for Claude Code — the Claude CLI agent.
mkdir -p ~/.claude/skills/flutter-upgrade curl -L https://claudskills.com/skills/flutter-upgrade/SKILL.md \ -o ~/.claude/skills/flutter-upgrade/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/flutter-upgrade/. Claude Code auto-discovers it on next session.
