Building a landing page / marketing site with Flutter? Let us review it.
Expert code review for landing page / marketing sites built with Flutter. We fix Flutter-specific security gaps, optimize performance, and handle deployment. From $19.
Common Flutter issues we find
Real problems from Flutter codebases we've reviewed.
API keys embedded in Dart source code
Secret keys and API credentials hardcoded in Dart files. Since Flutter web apps compile to JavaScript, these keys are visible to anyone who opens browser dev tools.
Inconsistent state management patterns
AI tools mix setState, Provider, Riverpod, and BLoC in the same project. This makes the app confusing to maintain and introduces subtle state synchronization bugs.
Large initial download size for web
Flutter web apps ship a large main.dart.js file by default. Without deferred loading and tree-shaking, the initial page load can take several seconds on slower connections.
No input validation before API calls
Form data sent to backend APIs without client-side validation, leading to poor user experience (errors only appear after a network round trip) and unnecessary server load.
Landing Page / Marketing Site challenges to solve
Key landing page / marketing site concerns that AI-generated code often misses.
Page speed
Landing pages must load in under 2 seconds. AI tools generate bloated CSS, unoptimized images, and unnecessary JavaScript that slow loading. A 1-second delay in load time reduces conversions by 7%.
SEO fundamentals
Missing meta descriptions, incorrect heading hierarchy, no Open Graph tags, no structured data, and no sitemap. AI tools build the visible content but skip the invisible SEO infrastructure.
Form handling
Your contact form, waitlist signup, or demo request form must work flawlessly. AI-generated forms often lack validation, error messages, success confirmations, and backend integration.
Mobile responsiveness
Over 60% of traffic is mobile. AI-generated layouts sometimes break on small screens — overlapping elements, unreadable text, and inaccessible buttons. Every pixel matters for conversion.
