Why now
Three moments when a Flutter audit is decisive
Before a fundraising round
Serious investors require a technical due diligence. A signed expert audit report meets that requirement directly, reduces friction and accelerates closing. It documents existing technical debt instead of letting it surface during negotiations.
After an intensive vibe coding phase
AI generates code that compiles. That's not code you ship to production without review. Suspicious patterns, exposed secrets, patched-together auth flows and API hallucinations are not caught by automated tests. An audit catches them.
Before an acquisition or strategic rewrite
Mapping technical debt before a transaction or rewrite lets you negotiate from a position of knowledge, prioritize refactor work, and avoid inheriting a codebase with hidden security or compliance issues.
Process
How it works
Five steps, no preliminary meeting. From payment to report, the process is designed not to interrupt your sprint.
Online order & payment
You choose your tier and pay via Stripe. An EURL DEVLOPN invoice is issued immediately, compliant with French VAT. No prior conversation required.
Repository access
You share access to your repo (GitHub, GitLab, Bitbucket) or send a ZIP archive. An NDA can be signed before any access if you wish.
Multi-agent analysis
Our specialized AI agents analyze the 8 categories in parallel: architecture, state, Flutter performance, mobile security, store compliance, dependencies, tests, and AI-generated code.
Expert review & signature
A Flutter expert reviews all findings, removes false positives (20–30 %), contextualizes each recommendation against your stack and constraints, then signs the report.
Report delivery
PDF report + PPT presentation delivered by email. The access link is secured and expires after 30 days. Your code is deleted from our systems within 30 days.
Re-check
If you subscribed to this option at checkout: once your fixes are in place, you trigger the re-check. Targeted check on initial findings. Delivered in 2–3 business days with a signed validation certificate. Must be used within 90 days (120 days for Due Diligence).
Methodology
An audit infrastructure,
not a prompt
Specialized agents by domain
Each agent is calibrated for its domain with its own references: OWASP Mobile Top 10, Apple and Google guidelines, official Flutter best practices. Not a generalist agent that covers everything superficially.
Structured file-by-file pipeline
Code is split, indexed, and analyzed with its full project context. Files are cross-referenced. A change in a service is related to its consumers.
Orchestrator agent
A dedicated agent consolidates all findings, deduplicates, and prioritizes by severity: Critical / High / Medium / Low / Info. The final report doesn't just list raw observations — it prioritizes them.
40+ checkpoint grid
The grid is calibrated upfront, with standardized recommendation templates. It ensures completeness and consistency from one audit to the next, regardless of the submitted code.
Evolving reference base
Each audit enriches the pattern library: recurring vulnerabilities, Flutter anti-patterns, AI-generated code signatures. System precision improves as the base grows.
Systematic human validation
20–30 % of raw LLM findings are false positives. The expert decides, contextualizes, reformulates. This is the step that makes the difference between an AI output dump and a signable report. It's not optional.
Multi-agent audit pipeline — terracotta accent: only human link
Scope
What's audited — Flutter & Native Mobile
Eight categories. Each finding is classified by severity, with an actionable recommendation and a reference (official spec, CVE, guideline). Not a checklist — an expert report.
01
Architecture & organization
- Clean Architecture, layer separation, dependency injection
- Modularization, routing management
- Structural consistency across the project
02
State management
- Bloc, Cubit, Riverpod, Provider — idiomatic usage
- Immutability, state propagation, side effects
- Stream and listener leaks
03
Flutter performance
- Unnecessary rebuilds, const constructors, ListView builders
- Image management, jank and frame budget (16 ms)
- Static analysis of render hot paths
04
Mobile security
- Flutter Secure Storage, plaintext secrets, certificate pinning
- iOS ATS, Android ProGuard and R8, obfuscation
- OWASP Mobile Top 10
05
Store compliance
- Info.plist, AndroidManifest, Apple privacy manifests
- Target SDK levels, declared vs. used permissions
- App Store / Google Play rejection risks
06
Dependencies
- pubspec.yaml, outdated or abandoned packages
- Known CVEs, version constraints
- Licenses and open source compliance
07
Tests & CI/CD
- Coverage, unit tests, widget tests, integration tests
- Pipelines, release process, gate quality
- Risks from missing tests on critical code
08
AI-generated code (cross-cutting)
- Suspicious patterns, exposed secrets, patched-together auth
- API hallucinations, dead code, unintentional duplication
- LLM generation signatures identified by our pattern base
Signing expert
The report is signed
Every DEVLOPN Audit report is reviewed and signed by a Flutter expert. This is not honorary: the signature commits the expert's responsibility on the retained findings, formulated recommendations, and dismissed false positives.
Current signing expert: Jeremy, mobile developer and architect, engagements at Renault Digital, SNCF and Thales. His experience in large organizations — security constraints, compliance, scale — directly informs his reading of audited codebases.
Option available on Audit Pro and Due Diligence
Like a technical inspection.
But for your code
An audit report that ends up in a forgotten Notion is worthless. The re-check verifies that findings have been fixed, without regression. You get a validation certificate signed by the expert, documenting your process for investors, your board, or in preparation for a regulatory audit.
01
Targeted re-scan on your findings
AI agents re-check only the findings from the initial audit. Each point is marked Fixed, Partially fixed, Not fixed, or Regression. No re-billing for a full audit.
02
Delivered in 2 to 3 business days
You trigger the re-check when your fixes are ready, within 90 days of the initial audit (120 days for Due Diligence). Re-check report delivered in 2 to 3 business days.
03
Signed validation certificate
If all critical and high findings are resolved, you receive a validation certificate signed by the expert, valid for 6 months. Usable as documentation in a due diligence, SOC 2/ISO 27001 preparation, or response to an enterprise security questionnaire.
The validation certificate commits DEVLOPN's professional responsibility on the accuracy of findings at the date of issuance. DEVLOPN is not an accredited certification body; the certificate does not substitute for ISO 27001, SOC 2, or ANSSI qualification.
At checkout: option at 790 € excl. VAT for Audit Pro, 1,790 € excl. VAT for Due Diligence. Not available for Audit Express.
The deliverable
What you receive
A report of 25 to 60 pages depending on project size, accompanied by a PPT presentation. Each finding includes context, impact, offending code, recommendation and reference. Nothing hollow.
Context
The application does not implement certificate pinning on its network requests. All communication with the backend API can be intercepted via a MITM proxy (Charles, Burp Suite) without obstacle in production.
Impact
User data exposed in transit (tokens, PII) · No SSL proxy detection · Not mitigated by Android/iOS obfuscation
Identified code
final dio = Dio(BaseOptions(baseUrl: _baseUrl));
// ← no certificate validation configured
Recommendation
Implement pinning via dio_certificate_pinning or ssl_pinning_plugin. Add validation in the global network interceptor. Test rejection via Charles Proxy before each store release.

Questions
What people ask us
Straight answers to real objections — confidentiality, AI infrastructure, scope, timelines.
How do you guarantee the confidentiality of my code?+
An NDA can be signed before any repository access — available as an option on all tiers, systematic on Due Diligence. Repo access is revocable at any time from your GitHub, GitLab or Bitbucket interface. Your code is deleted from our systems no later than 30 days after report delivery.
Do your AI agents send my code to OpenAI or Anthropic?+
The infrastructure uses Anthropic's Claude API in zero-data-retention mode: requests are not used to train models. The exact technical modalities will be specified in the contract and data processing notices. If your context requires specific constraints (sovereign cloud, air gap), contact us before ordering.
Who is the expert who signs my report?+
The current signing expert is Jeremy, mobile developer and architect with engagements at Renault Digital, SNCF and Thales. His background in high-constraint environments (security, compliance, scale) directly informs his reading of codebases. His full identity is disclosed with the signed report.
Why not a continuous SaaS like CodeRabbit or SonarQube?+
Continuous SaaS tools analyze code in a stream, rule by rule. They're excellent for daily linting. They don't do transverse architectural reviews, don't detect AI-generated code patterns, don't contextualize findings against your stack and business constraints, and don't produce a transferable report signed by a human.
These are complementary tools, not competitors.
What is the re-check option?+
A targeted re-check on the initial audit's findings, to be subscribed at checkout for 790 € excl. VAT (Audit Pro) or 1,790 € excl. VAT (Due Diligence). You trigger it when your fixes are ready, within 90 days of the audit (120 days for Due Diligence). You receive a re-check report and, if critical findings are resolved, a signed validation certificate valid for 6 months. Not available on Audit Express.
What is the validation certificate worth?+
It's a document signed by the expert attesting that the critical and high findings from the initial audit have been resolved without regression, at a given date. It can be used as supporting documentation in a technical due diligence (fundraising, acquisition), in preparation for a regulatory audit (SOC 2, ISO 27001), or in response to an enterprise security questionnaire. It doesn't replace an ISO or SOC certification, but it documents an external code review process and follow-up on corrections.
Do you audit native iOS and native Android, or only Flutter?+
We audit Flutter apps, native iOS (Swift / Objective-C), native Android (Kotlin / Java), and Flutter projects with native modules. Analysis categories adapt: mobile security and store compliance are universal, state management and performance categories are calibrated per platform.
What if a large portion of my code was generated by AI?+
That's precisely the use case for which we built the "AI-generated code" category. Our pattern base recognizes LLM generation signatures, API hallucinations, patched-together auth, and dead code typical of these workflows. The more AI-generated code there is, the more useful the audit.
Payment terms, refund policy?+
Payment is due at checkout via Stripe. If the audit cannot start (access not provided within 5 business days, inaccessible repo), the full amount is refunded. Once analysis has begun, refunds are not possible — but we commit to delivering within the announced timelines or refunding the difference.
Can I have a video debrief?+
The one-hour video debrief with the expert is included in the Due Diligence tier. It allows you to walk through critical findings, ask questions and prioritize actions. It's not available as an option on Express and Pro tiers — if it's important to you, Due Diligence is the right choice.
