ayushyaandClaude Opus 5.5 56784ef212 Rebuild UI on the Noo design system
Replaces the Material 3 screens with the Noo design system: warm
neutrals, one violet accent, pill controls, Schibsted Grotesk/
Instrument Sans, Lucide icons, no gradients/shadows.

- New lib/widgets/noo/ component kit (core, lists, files, media, nav,
  overlays) plus lib/theme/design_tokens.dart for the color/type/space/
  radius/motion tokens.
- Rebuilt the app shell (top/bottom bars, drawer, desktop sidebar and
  toolbar), every tab (Files/Offline, Photos, Favorites, Recent,
  Activity, Trash, Shares), Settings, the lock and login screens, the
  media viewer, search, the details/share sheets, and the share-upload
  and move/copy destination pickers.
- Added a design canvas (linked from DESIGN_SYSTEM.md) covering the
  screens the spec didn't already describe, with matching Android and
  iOS chrome; wrote up the approved recipes into DESIGN_SYSTEM.md §4.
- Removed now-dead legacy widgets (media_grid_tile, swipeable_item,
  sync_status_badge, selectable_thumbnail) and updated
  architecture.md/styling.md/standards.md to describe the new
  structure and component/testing conventions.
- Added widget tests for the noo/ component kit.

This is a UI-only rework: no provider/model/service behavior changed.

description: Diagnoses and fixes Flutter's "plugin applies Kotlin Gradle Plugin (KGP)" build warning - the one that names specific plugins (e.g. "Your app uses the following plugins that apply Kotlin Gradle Plugin (KGP): file_saver, pdfx") and links to the Built-in Kotlin migration guide. Use whenever `flutter build`/`flutter run` prints this warning, or when checking whether it's safe to upgrade a plugin that previously triggered it.

You fix Flutter's Kotlin Gradle Plugin (KGP) migration warning, which looks
like:
```
WARNING: Your app uses the following plugins that apply Kotlin Gradle Plugin (KGP): file_saver, pdfx
Future versions of Flutter will fail to build if your app uses plugins that apply KGP.
```
## Background
Flutter is moving to a model where the Flutter Gradle plugin applies Kotlin
itself ("Built-in Kotlin"), rather than each Android plugin applying its own
copy of the Kotlin Gradle Plugin in its `android/build.gradle`. Plugins that
haven't migrated yet trigger this warning today and will hard-fail the build
in a future Flutter release. The fix lives upstream, in the plugin's own
`android/build.gradle` (removing its own `apply plugin:
'kotlin-android'`/`id("kotlin-android")` in favor of Flutter's built-in
support) - not in this app.
Reference: https://docs.flutter.dev/release/breaking-changes/migrate-to-built-in-kotlin/for-app-developers
## What to do
1. Run `flutter build apk --release` (faster than `appbundle`) or use the
warning text the user already has, to get the exact list of named
plugins.
2. For each plugin, find its current pinned version in `pubspec.yaml` and
the resolved version in `pubspec.lock`.
3. Check whether a newer published version has migrated:
- Check the plugin's CHANGELOG.md (pub.dev shows it, or the package's
GitHub repo) for entries mentioning "Built-in Kotlin", "KGP", or
removing `kotlin-android` from its `android/build.gradle`.
- If unsure from the changelog alone, fetch the candidate version's
`android/build.gradle` from pub.dev/GitHub directly and check whether
it still applies the Kotlin Gradle Plugin itself.
4. If a migrated version exists and satisfies (or can reasonably relax) the
app's other constraints:
- Bump the version constraint in `pubspec.yaml`.
- Run `flutter pub get`.
- Rebuild (`flutter build apk --release` is enough to confirm) and
verify that specific plugin no longer appears in the warning's list.
- Run `flutter analyze` and skim for anything the upgrade broke (API
changes) before calling it done.
5. If no migrated version exists yet:
- Do not attempt to silence the warning (no Gradle flags, no
suppressing build output) - it is telling the truth about a real
future break.
- Do not fork or hand-patch the plugin's Android Gradle files inside
`pub-cache` - that gets overwritten on the next `flutter pub get` and
isn't tracked by the repo anyway.
- Report which plugin(s) are still blocked, their current version, and
whether the upstream issue tracker already has an open issue for this
(search it) - file a note for the user rather than opening the issue
yourself.
## Reporting
For each plugin named in the original warning, state one of:
- **Fixed**: upgraded from `X` to `Y` in `pubspec.yaml`, confirmed the
warning no longer names it.
- **Blocked**: still on `X`, no migrated release exists yet, link to the
changelog/issue you checked.
Keep the report short - a couple of lines per plugin is enough.
