Flutter Use Http Package

Need a Flutter networking guide you can actually follow without digging through docs? This skill walks through the `http` package for GET, POST, PUT, and DELETE calls against a REST API. It covers the boring-but-breaking setup first: the INTERNET permission on Android and the network client entitlement on macOS, both of which fail silently if you forget them. The useful opinion buried in here is the error handling: it says to throw on non-success status codes rather than return null, because returning null leaves a FutureBuilder spinning forever. It also pushes JSON parsing into a background isolate via compute() to avoid frame drops on large payloads. The worked example fetches a photo list, parses it off the main thread, and wires it into a FutureBuilder with proper loading and error states. Good starting point if you're new to Flutter networking.

Configuration & Permissions

Configure the environment and platform-specific permissions required for network access.

Add the http package dependency via the terminal:
```
flutter pub add http
```

Import the package in your Dart files:

import 'package:http/http.dart' as http;

Configure Android permissions by adding the Internet permission to android/app/src/main/AndroidManifest.xml:
```
<uses-permission android:name="android.permission.INTERNET" />
```
Configure macOS entitlements by adding the network client key to both macos/Runner/DebugProfile.entitlements and macos/Runner/Release.entitlements:
```
<key>com.apple.security.network.client</key>
<true/>
```
