Engineering for Zero Latency
A feature-first Flutter client paired with native Android RemoteViews widgets and a high-throughput Go HTTP standard-library backend.
Native RemoteViews
Widgets do not spin up an expensive Flutter engine on every click. Kotlin AppWidgetProviders validate answers, calculate attempts, and redraw instantly via partial updates.
Riverpod Layered State
Feature-first architecture where presentations observe Riverpod controllers, and repositories coordinate local SQLite state with remote API requests.
HomeWidget Bridge
Shared SharedPreferences between Kotlin native widget broadcasts and Flutter dashboards guarantees that practice progress is never desynced.
