Flutter Project Structure

Use when deciding Flutter feature folders, local Dart packages, pub workspace or monorepo packages, plugin or federated plugin splits, package exports, or where Dart and native (Kotlin/Swift) platform code should live.

Do not use for behavior inside an existing owner; use platforms/flutter/skills/flutter-architecture/SKILL.md or the matching widget/state card.

Read

• references/current-guidance.md for the smallest-owner ladder, file split rules, project families, split decision, dependency direction, layouts, and migration strategy.
• platforms/flutter/skills/flutter-architecture/references/reusable-layers.md when the split is motivated by reuse across features or apps.
• platforms/flutter/skills/flutter-platform-integration/references/mobile-native-bridges.md when native code, generated channel code, or a plugin package is placed.
