Flutter 3.47 moved Material and Cupertino out of the SDK into material_ui and cupertino_ui, which ship weekly. The SDK imports are deprecated from the November 2026 stable release and removed in 2027, and the strict pre-push check would block every push then. The app's one Material import now comes from material_ui ^1.5.0, so everything built from here on uses the new import.

Packages that still import package:flutter/material.dart (Serverpod's Flutter packages, later the rich-text editor) see the app's theme and localizations only through MaterialUiCompatibilityBridge, set in MaterialApp.builder. The bridge is deprecated on purpose, as a reminder to remove it, so its use carries a documented ignore until those packages have moved.

google_fonts is removed: it was unused, and by default it downloads fonts from Google at runtime, which sends every user's IP address to Google.

- **Time comes from `clock.now()`** (`package:clock`), never `DateTime.now()`, in server and app. Why: scheduling, streaks and expiry are deterministic under test (`withClock`, `fakeAsync`), and because Serverpod itself reads `clock.now()` (e.g. session expiry), `withClock` controls its behaviour too.
- **UTC for storing and sending, local time for display and day boundaries.** Serverpod sends `DateTime` as UTC and stores it in `timestamp without time zone` columns. Compare and compute in UTC; call `.toLocal()` only to display. "Due today", streaks and daily goals use the learner's **local** calendar day, computed on the client; the server never needs day boundaries.
- **Build configuration comes from `--dart-define`.** The client holds no secrets, ever.
- **Material comes from `package:material_ui`** (Cupertino from `package:cupertino_ui`), never from `package:flutter/material.dart`, which Flutter deprecates from its November 2026 release on. Packages still on the SDK's copy get the app's theme and localizations through `MaterialUiCompatibilityBridge` in `MaterialApp.builder`; remove it once they have moved.
