Introduction

stackchain scaffolds a Flutter app from a simple YAML config — and keeps helping as the project grows.

Version 1.4.0 · MIT · pub.dev

In one sentence

Write your preferred stack in stackchain.yaml → run init → get a real app structure → add features and tests with one command.

Why bother?

Most generators dump folders once, then disappear. stackchain stays as a dev dependency so you can:

• Add a feature — files, routes, DI, and tests in one command (crud for list/form slices)
• Generate from OpenAPI — api openapi.yaml for models + API repos (re-run safe)
• Generate tests — unit, widget, integration (test auth); stub custom methods with stub
• Rename or remove — without leftover routes or DI registrations
• Change stack later — e.g. Riverpod → Bloc with migrate (custom regions ported)
• Keep custom code — // <stackchain:custom> and *_custom_test.dart
• Heal drift — doctor --fix syncs markers and refreshes the lockfile

Mental model

stackchain.yaml  →  init / feature / sync  →  your Flutter app

You edit YAML (or pick a preset). The CLI generates and wires the project. You write business logic outside the markers.

Tip

Create the Flutter app first with flutter create. stackchain scaffolds into it — it does not replace flutter create.
