Flutter Release Pipeline

Build and package Flutter Android release artifacts (APK/AAB), collect outputs into a single folder, and produce a short release checklist. Use when the user asks to build APK/AAB, prepare a Play Store release, bump version, gather mapping/symbols, or generate a deterministic release folder for sharing.

Flutter Android Release Pipeline

Workflow

1. Preflight

• Confirm flutter --version works.
• Confirm project path contains pubspec.yaml.

2. Build (choose one)

• AAB: flutter build appbundle --release
• APK: flutter build apk --release (optionally --split-per-abi)

3. Collect artifacts Create out/flutter_release_<timestamp>/ and copy:

• build/app/outputs/flutter-apk/*.apk (if APK build)
• build/app/outputs/bundle/release/*.aab (if AAB build)
• build/app/outputs/mapping/release/mapping.txt (if present)
• pubspec.yaml (snapshot)

4. Report

• Print paths + sizes + SHA256 for each artifact.
• Print a short checklist (versionCode/versionName sanity, signing, Play Console notes).

Script

Run (PowerShell):

• powershell -ExecutionPolicy Bypass -File scripts/flutter_release.ps1 -Project "<path>" -Mode aab|apk -SplitPerAbi:$false

Notes

• Avoid changing app code unless explicitly requested.
• If build fails, return the exact error + suggested fix.
