Flutter App

flutter-app

Bootstrap a new Flutter app the way this owner builds them: FVM-pinned SDK, clean architecture (feature-first), Riverpod for state, an Either/Failure error model, current stable packages, and the house git and CI workflow with release-please and Play Store delivery.

First read the shared rules (they override anything you remember): ../shared/house-rules.md, ../shared/no-ai-attribution.md, ../shared/git-and-ci.md, ../shared/docs-and-context.md, ../shared/hardening.md, and (for public repos) ../shared/open-source-docs.md.

Step 0. Get the brief, then ask the variant questions (hard stop)

This is a hard stop. Do not run any scaffolding command until the user has answered.

First, get the project brief: one paragraph on what the app does, its main features, target users, and any hard constraints. If the user has not given one, ask for it. The brief drives naming, the feature list, and the data model.

Then ask the variant questions. If a choice has multiple options, ask; do not assume. Ask in one batch, then proceed.

1. Repo visibility: private, open-source, or private-plus-open-source.
2. Backend: BYOK (each user supplies their own LLM key, no backend), a custom backend (Dio + JWT auth), or none yet. See references/architecture.md.
3. State codegen: Riverpod with codegen (@riverpod + build_runner) or plain Riverpod with hand-written providers. Default: codegen.
4. Local data: Drift, Isar, shared_preferences only, or none yet.
5. Auth: Google Sign-In, none, or backend-driven.
6. Release target: Play Store (default), App Store, or both.

If the user already answered some, do not re-ask.

Step 1. Pin the SDK with FVM and verify versions

• Use FVM so the SDK is pinned per project: fvm use stable (or a specific stable). Every command runs through fvm flutter ....
• Run fvm flutter --version and record the real Flutter and Dart versions in the project docs.
• Run scripts/check-latest.sh for current stable package versions from pub.dev. Pin those, not versions from memory (../shared/house-rules.md rule 2).
• Pull current docs for Flutter, Riverpod, and any codegen packages via Context7 before writing code (../shared/docs-and-context.md). Riverpod's provider syntax and codegen naming change between majors; confirm before writing.

Step 2. Scaffold with the official CLI

fvm flutter create --org com.<owner>.<app> --platforms=android,ios <name>

Then add dependencies from references/stack.md and lay out the folders from references/architecture.md.

Step 3. Apply architecture and conventions

• Clean-architecture layers, feature structure, Either/Failure model, DI, and the non-negotiable conventions (use cases, datasource interface plus impl, custom widgets, extensions, central utils, constants for everything, zero hardcoding): references/architecture.md.
• Riverpod and Flutter do's and don'ts, and code smells to avoid: references/best-practices.md.
• Dependency set and pinning notes (some packages must be pinned to avoid analyzer conflicts): references/stack.md.
• Production hardening (obfuscated release builds, no baked-in secrets, no debug symbols in git): ../shared/hardening.md.

Step 4. Git, CI, release, docs, security

• Git branch model, conventional commits, auto-merge, release-please: ../shared/git-and-ci.md.
• CI (analyze + test), signing, and Play Store delivery: references/quality-gates.md.
• Gitignore signing keys, keystore, google-services.json, and .env*. Store them as CI secrets. Provide .env.example.
• Add docs/ (git-workflow, architecture, release-process) and a README. For a public repo, ship the full open-source docs set per ../shared/open-source-docs.md and run the open-source hard gate in ../shared/no-ai-attribution.md before the first push.

Step 5. Verify before declaring done

Run the gates in references/quality-gates.md: fvm flutter analyze must be zero issues, fvm flutter test green, and the app must build and run. Report real results.
