Networking#

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 in the Android manifest (AndroidManifest.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.

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