SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires http.

What problem does it solve? Flutter developers often struggle with correctly configuring network permissions, handling HTTP responses, and avoiding UI jank when parsing large JSON payloads. This Skill provides a complete workflow for executing REST API calls with proper error handling and background parsing. ## Core Features & Use Cases - Platform Configuration: Guides setup of Android Internet permissions and macOS network entitlements required for HTTP access. - Typed Request Execution: Implements GET, POST, PUT, and DELETE requests with headers, JSON-encoded bodies, and status code validation mapped to strongly typed Dart models. - Background JSON Parsing: Uses Flutter's compute() function to offload expensive JSON deserialization to a separate isolate, preventing frame drops. - Use Case: Fetch a list of photos from a REST API, parse the JSON response in a background isolate, and display results in a ListView via FutureBuilder with loading and error states. ## Quick Start Use the http package to fetch a list of items from my REST API endpoint and display them in a FutureBuilder with proper error handling.

Frequently Asked Questions about flutter-use-http-package

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I make HTTP requests in Flutter?▼

Add the http package with flutter pub add http, import it as http, and call methods like http.get() or http.post() with a Uri.parse() URL. Validate response.statusCode and parse the body with jsonDecode into a typed Dart model.

How to parse large JSON responses in Flutter without freezing the UI?▼

Use Flutter's compute() function from package:flutter/foundation.dart to run parsing in a background isolate. The parsing function must be top-level or static, since closures and instance methods cannot cross isolate boundaries.

Why does my Flutter HTTP request fail on Android or macOS?▼

Android requires the INTERNET permission in AndroidManifest.xml, and macOS requires the com.apple.security.network.client entitlement in both DebugProfile and Release entitlements files. Missing either blocks all network access.

Should I return null when a Flutter HTTP request fails?▼

No, throw an Exception for non-success status codes instead. Returning null prevents FutureBuilder from entering its error state, leaving the UI stuck on a loading indicator indefinitely.

What status codes indicate success for REST API calls in Flutter?▼

Treat 200 OK as success for GET, PUT, and DELETE requests, and 201 CREATED for POST requests. Any other status code should trigger an explicit exception with the status included in the message.
