Finishing a Flutter Development Branch

Overview

Guide completion of Flutter development work by presenting clear options and handling chosen workflow.

Core principle: Verify tests → Present options → Execute choice → Clean up

Announce at start: "I'm using the flutter-finishing skill to complete this work."

The Process

Step 1: Verify Tests and Analysis

Before presenting options, verify everything passes:

# Static analysis
flutter analyze
# Expected: No issues found!

# All tests
flutter test
# Expected: All tests passed!

# Build check — required once here, against the project's target platform
# (apk / ios / web / windows / macos / linux). Skip only if the platform
# toolchain is unavailable in this environment, and say so in the report.
flutter build <target> --debug
# Expected: Built successfully

If tests fail:

Flutter tests failing (N failures). Must fix before completing:

[Show failures]

Cannot proceed with merge/PR until tests pass.

STOP. Don't proceed to Step 2.

If tests pass: Continue to Step 2.

Step 2: Determine Base Branch

# Find merge base
git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null

# Or ask: "This branch split from main - is that correct?"

Step 3: Present Options

Present exactly these 4 options:

Implementation complete. All tests passing. What would you like to do?

1. Merge back to <base-branch> locally
2. Push and create a Pull Request
3. Keep the branch as-is (I'll handle it later)
4. Discard this work

Which option?

Don't add explanation - keep options concise.

Step 4: Execute Choice

Option 1: Merge Locally

# Switch to base branch
git checkout <base-branch>

# Pull latest
git pull

# Merge feature branch
git merge <feature-branch>

# Verify tests on merged result
flutter analyze
flutter test

# If tests pass, delete feature branch
git branch -d <feature-branch>

Then: Cleanup worktree (Step 5)

Option 2: Push and Create PR

# Push branch
git push -u origin <feature-branch>

# Create PR
gh pr create --title "<feature-title>" --body "$(cat <<'EOF'
## Summary

)"

Don't cleanup worktree - might need for PR review fixes.

Option 3: Keep As-Is

Report: "Keeping branch <name>. Worktree preserved at <path>."

Don't cleanup worktree.

Option 4: Discard

Confirm first:

This will permanently delete:
- Branch: <name>
- All commits: <commit-list>
- Worktree at: <path>

Type 'discard' to confirm.

Wait for exact confirmation.

If confirmed:

git checkout <base-branch>
git branch -D <feature-branch>

Then: Cleanup worktree (Step 5)

Step 5: Cleanup Worktree

For Options 1, 2, 4:

Check if in worktree:

git worktree list | grep $(git branch --show-current)

If yes:

# Navigate to main repo
cd <main-repo-path>

# Remove worktree
git worktree remove <worktree-path>

For Option 3: Keep worktree.

Quick Reference

Flutter-Specific Verification

Before allowing completion:

# 1. Analysis must pass
flutter analyze
# Must show: No issues found!

# 2. Tests must pass
flutter test
# Must show: All tests passed!

# 3. Build verification — once, per project target platform (see Step 1)
flutter build <target> --debug
# Must show: Built successfully

Common Mistakes

Skipping test verification

• Problem: Merge broken code, create failing PR
• Fix: Always verify tests before offering options

Open-ended questions

• Problem: "What should I do next?" → ambiguous
• Fix: Present exactly 4 structured options

Automatic worktree cleanup

• Problem: Remove worktree when might need it (Option 2, 3)
• Fix: Only cleanup for Options 1 and 4

No confirmation for discard

• Problem: Accidentally delete work
• Fix: Require typed "discard" confirmation

Red Flags

Never:

• Proceed with failing tests
• Merge without verifying tests on result
• Delete work without confirmation
• Force-push without explicit request
• Skip flutter analyze

Always:

• Verify tests before offering options
• Present exactly 4 options
• Get typed confirmation for Option 4
• Clean up worktree for Options 1 & 4 only

Integration

Called by:

• flutter-subagent-dev (after all tasks complete)
• flutter-executing (after all batches complete)

Pairs with:

• flutter-worktrees - Cleans up worktree created by that skill
