Flutter Dart Code Review

A thorough code review checklist that catches the stuff that actually breaks Flutter apps in production. It covers the usual suspects like widget decomposition and const usage, but also digs into Dart language pitfalls that slip past less strict linters: implicit dynamics, late overuse, catching Error subtypes, and ignoring Future return values. The state management section is genuinely library agnostic, with specific guidance for both immutable patterns like BLoC and Riverpod and reactive mutation approaches like MobX and Signals. Particularly useful for the async state modeling advice, which steers you away from boolean flag soup toward sealed types that make impossible states unrepresentable. Use this during PR reviews or when inheriting a codebase to spot architectural issues early.

Flutter/Dart Code Review Best Practices

Comprehensive, library-agnostic checklist for reviewing Flutter/Dart applications. These principles apply regardless of which state management solution, routing library, or DI framework is used.

1. General Project Health

Project follows consistent folder structure (feature-first or layer-first)
Proper separation of concerns: UI, business logic, data layers
No business logic in widgets; widgets are purely presentational
pubspec.yaml is clean — no unused dependencies, versions pinned appropriately
analysis_options.yaml includes a strict lint set with strict analyzer settings enabled
No print() statements in production code — use dart:developer log() or a logging package
Generated files (.g.dart, .freezed.dart, .gr.dart) are up-to-date or in .gitignore
Platform-specific code isolated behind abstractions

2. Dart Language Pitfalls
