Mobile Flutter

Mobile Flutter Skill

Core Principles

• const widgets everywhere: const constructor = compile-time constant = O(1) rebuild check.
• Riverpod 2 with codegen: @riverpod annotation — generated code is the contract; never manual provider wiring.
• GoRouter 14+ for navigation: Declarative routing, type-safe @TypedGoRoute, StatefulShellRoute for tab state.
• AsyncValue pattern: Typed loading/error/data states — never manual isLoading/hasError bools.
• Extension types for domain safety: extension type UserId(String _) implements String {} — zero-cost, compile-time safe.
• WASM for web: flutter build web --wasm is the production default; dart:js_interop replaces dart:html.
• Impeller is the default: No SkSL pre-warming needed; consistent 60/120fps on iOS (Metal) and Android (Vulkan).
