Building a ai wrapper / llm app with Flutter? Let us review it.
Expert code review for ai wrapper / llm apps 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.
AI Wrapper / LLM App challenges to solve
Key ai wrapper / llm app concerns that AI-generated code often misses.
API cost management
LLM API calls are expensive. A single unoptimized prompt can cost cents per request — which adds up fast with real users. You need token counting, cost tracking, usage limits per user, and prompt optimization to stay profitable.
Response time variability
LLM responses take 1-30 seconds depending on prompt complexity, model load, and output length. Your UI needs streaming responses, loading states, and timeout handling. Users abandon apps that feel slow.
Error handling for AI responses
The AI model might: return an error, time out, return malformed output, refuse to answer, or hallucinate. Each case needs specific handling. AI tools build the happy path but not the many failure modes.
Prompt injection and security
Users can manipulate your AI's behavior through carefully crafted inputs — making it ignore instructions, reveal system prompts, or produce harmful output. Input sanitization and output validation are essential.
What we check
Key areas we review for Flutter ai wrapper / llm app projects.
API key security — LLM API keys stored server-side, never exposed to client
Cost controls — per-user limits, token counting, usage monitoring
Streaming implementation — proper SSE/streaming for LLM responses
Error handling — timeouts, rate limits, model errors, malformed output
