# Networking

> Internet network calls in Flutter.



## Cross-platform http networking

The [`http`][] package provides the simplest way to issue http requests. This
package is supported on Android, iOS, macOS, Windows, Linux and the web.

## Platform notes

Some platforms require additional steps, as detailed below.

### Android

Android apps must [declare their use of the internet][declare] in the Android
manifest (`AndroidManifest.xml`):

```xml
<manifest xmlns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET" />
 <application ...
</manifest>
```

### macOS

macOS apps must allow network access in the relevant `*.entitlements` files.

```xml
<key>com.apple.security.network.client</key>
<true/>
```

Learn more about [setting up entitlements][].

WebSockets, and parsing data in the background) see the
