Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "flutter-expert" from https://skillstore.io/skills/sickn33-flutter-expert.md and its manifest at https://skillstore.io/api/skills/sickn33-flutter-expert/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "flutter-expert". Choose state management for a small application with authentication, settings, and cached API data.

Expected outcome:

  • Recommendation: Riverpod for explicit dependencies, testable providers, and manageable asynchronous state.
  • Structure state by feature and keep network and storage logic behind repositories.
  • Test provider transitions for loading, data, refresh, and failure conditions.

Using "flutter-expert". Outline a performance review for a scrolling product catalog.

Expected outcome:

  • Measure frame timing, rebuild counts, image decoding, memory growth, and network latency on representative devices.
  • Use lazy lists, stable keys, cached image sizes, constant widgets, and isolated state updates.
  • Add performance tests for long lists, rapid scrolling, image failures, and low-memory conditions.

Using "flutter-expert". Plan native biometric authentication for Android and iOS.

Expected outcome:

  • Define fallback behavior, permission messaging, secure token storage, and platform availability checks.
  • Separate biometric verification from server authorization and never treat local authentication as a replacement for token validation.
  • Test enrollment changes, lockouts, cancellations, unsupported devices, and application lifecycle transitions.

What You Can Build

Plan a New Application

Select architecture, state management, storage, testing, and deployment approaches for a new Flutter product.

Improve an Existing Codebase

Identify widget, rendering, state, memory, accessibility, and testing improvements in an established application.

Integrate Native Features

Plan platform channels, permissions, secure storage, signing, and release requirements for Android and iOS.

Try These Prompts

Create a Flutter Screen 
Create an accessible Flutter screen for [feature] using Dart 3. Include loading, empty, error, and success states.
Choose State Management 
Compare Riverpod, Bloc, and Provider for [application]. Recommend one based on team size, state complexity, testing, and maintenance.
Diagnose Performance 
Review these Flutter performance symptoms: [symptoms]. Propose measurements, likely causes, targeted changes, and tests for mobile and web.
Design a Production Architecture 
Design a production Flutter architecture for [requirements]. Cover modules, data flow, offline synchronization, security, testing, observability, and multi-platform deployment.

Best Practices

  • Provide target platforms, Flutter version, constraints, and current architecture before requesting guidance.
  • Profile on representative devices and verify generated changes with automated tests.
  • Include accessibility, error handling, privacy, and deployment requirements from the beginning.

Avoid

  • Do not select state management only because it is popular.
  • Do not optimize performance without measurements from realistic devices and workloads.
  • Do not assume one interface, permission model, or deployment process works identically across platforms.

Frequently Asked Questions

Which Flutter versions does this skill cover?
It focuses on Flutter 3.x and Dart 3.x. Verify package compatibility and current platform requirements before implementation.
Can it choose a state management library?
Yes. It can compare Riverpod, Bloc, Provider, GetX, and other approaches using your project constraints.
Does it support mobile, web, and desktop?
Yes. It addresses shared architecture and platform-specific behavior for mobile, web, desktop, and embedded targets.
Can it review an existing Flutter project?
Yes. Provide relevant files, symptoms, constraints, and test results for focused architecture, quality, or performance guidance.
Does it execute builds or deployments automatically?
No. It provides implementation and deployment guidance, while execution depends on available tools, credentials, and explicit permissions.
Can its output replace testing and security review?
No. Validate all changes with project tests, device checks, current documentation, and appropriate security review.
