Remove Platform Skill

This skill defines the process for completely removing all files, configurations, and dead code associated with the web platform from the codebase when restricted to mobile (Android/iOS) only.

1. Delete Web and Deployment Files

Delete the web/ directory and any web-only deployment/configurations from the project root:

Delete the web platform folder: web/
Delete the web deployment configurations (e.g., Dockerfile, nginx.conf).

2. Clean Up Web Dependencies

Remove web-only plugins or packages from the dependencies list in the root pubspec.yaml:

Open pubspec.yaml.

Delete the flutter_web_plugins dependency:

-  flutter_web_plugins:
-    sdk: flutter

Run melos package bootstrap:
```
melos bootstrap
```

3. Delete app_ui Web Components

Delete the web-specific design and styling components in packages/app_ui:

Delete the web-specific exports file (e.g., packages/app_ui/lib/app_ui_web.dart).
Delete the web-specific widgets directory (e.g., packages/app_ui/lib/src/widgets/web/).

4. Clean Up Bootstrap Files

Remove web-specific initializers in lib/src/_bootstrap/ (or equivalent setup):

Delete any _web.dart bootstrap files.

Remove HTML conditional imports from the main bootstrap file:

-import 'package:my_app/.../_stub.dart'
-    if (dart.library.html) '_web.dart'
-    if (dart.library.io) '_native.dart'
-    as lib;
+import 'package:my_app/.../_stub.dart'
+    if (dart.library.io) '_native.dart'
+    as lib;

5. Scan and Delete Web View Files

In features, web views typically follow a naming convention like *_view_web.dart, while mobile views use *_view.dart. Scan the lib/ directory for any files matching *_view_web.dart and delete them.

6. Clean Up Page and Routing References

Remove imports and references to the deleted web views inside the corresponding parent pages:

Remove the import lines for *_view_web.dart files.

Simplify conditional instantiation of the view, using the mobile view only:

-return kIsWeb ? MyViewWeb(props) : MyView(props);
+return MyView(props);

Remove error delegation or other conditional calls referencing the web view:

-if (kIsWeb) {
-  MyViewWeb.delegateError(context, message);
-} else {
-  MyView.delegateError(context, message);
-}
+MyView.delegateError(context, message);

7. Thoroughly Prune kIsWeb Conditional Logic

Search the codebase for kIsWeb and prune the conditional branches:

Router: Remove web-only routes and checks in routing configurations.

-initialLocation: kIsWeb ? WebRoute.path : MobileRoute.path,
+initialLocation: MobileRoute.path,

State Notifiers: Inside state managers, unconditionally execute the mobile flows.
```
-if (!kIsWeb) _listenToUpdate();
+_listenToUpdate();
```
UI Packages: Search packages/app_ui for kIsWeb usages and remove the web-specific logic.

8. Clean Up Firebase Configurations

If Firebase is configured, remove web guards in the initialization flow:

In Firebase setup files, remove return guards:
```
-if (kIsWeb) return;
```

9. Verification and Re-generation

After cleanups, run code generation and static analysis to ensure all broken references are resolved:

# Re-generate code models/riverpod providers
melos run generate

# Run static analysis
melos run analyze
