SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses issues where applications fail to handle API errors gracefully, leading to poor user experiences with blank screens, missing feedback, and unresponsive behavior.

Core Features & Use Cases

  • API Error Handling: Implements executeAsync for robust API call management.
  • User Feedback: Ensures clear success and error messages, including toast notifications.
  • UI Resilience: Utilizes AsyncBlocBuilder with skeletonBuilder, builder for empty states, and errorBuilder for retry mechanisms.
  • Data Integrity: Protects against JSON parsing errors using tryParse and nullish coalescing.

Quick Start

Review the Cubit and View layers to ensure proper implementation of executeAsync, AsyncBlocBuilder, and user-facing error messages.

FAQPage Schema
How do I handle API errors in Flutter without showing a blank screen?

To handle API errors in Flutter without blank screens, implement `AsyncBlocBuilder` with an `errorBuilder` for retry mechanisms and a `skeletonBuilder` for loading states. This approach ensures clear user feedback and UI responsiveness during API failures.

What is the best way to show user feedback for API failures in a Flutter Cubit?

The best way to show user feedback for API failures in a Flutter Cubit is implementing the `executeAsync` method. It manages API calls robustly and triggers clear success or error messages, including toast notifications, ensuring users are informed about the application's state.

How do I prevent Flutter app crashes from invalid JSON parsing during API calls?

Prevent Flutter app crashes from invalid JSON parsing by using safe parsing techniques. The Skill implements `tryParse` and nullish coalescing to protect against JSON parsing errors, ensuring data integrity and preventing unresponsive behavior when API responses are malformed.

Does this API error handling approach work with Flutter Cubit state management?

Yes, this API error handling approach is built for Flutter Cubit state management. It implements `executeAsync` within Cubits to manage API calls and uses `AsyncBlocBuilder` in Views to handle loading, empty, error, and success states.

Why does my Flutter app become unresponsive when an API request fails?

A Flutter app becomes unresponsive when an API request fails due to lack of error handling and retry logic. Implementing `executeAsync` in Cubits and `AsyncBlocBuilder` with retry mechanisms in Views addresses this unresponsiveness by gracefully managing API failure states.
