Riverpod (Flutter)
A reactive state-management library for Flutter — a modern replacement for Provider — built around compile-safe Providers, async value handling, and code generation. VULK's Flutter generator uses Riverpod 2 by default.
Riverpod (Flutter)
Riverpod is the most widely-adopted state-management library in Flutter, written by the same author as the older Provider package. It moves state out of the widget tree (so BuildContext is no longer required to read it), gives every piece of state a typed Provider identifier, and ships first-class AsyncValue<T> for loading / error / data states, family providers for parameterized state, and a code-generation flavor (@riverpod) that turns a function into a typed provider. It pairs well with go_router and Freezed.
VULK generates every Flutter project with Riverpod 2 + @riverpod code-gen as the default state layer. The generation agent scaffolds the providers/ folder, wires flutter_riverpod into main.dart via ProviderScope, and uses the canonical AsyncValue.when(data:, loading:, error:) pattern for any screen that fetches data.
Network Tokens
Tokenized card credentials issued by Visa, Mastercard, and Amex that replace the real PAN at the merchant. They auto-update when the card is reissued, lifting authorization rates by 2-7 percentage points on subscription renewals.
go_router (Flutter)
The official declarative routing package for Flutter, built on the Router API. Supports deep links, redirects, nested navigators, and type-safe routes via code generation. VULK uses go_router for every Flutter project.
