Cross-platform http networking
The http package provides the simplest way to issue http requests. This package is supported on Android, iOS, and the web.
Platform notes

Android
Android apps must declare their use of the internet in the Android manifest (AndroidManifest.xml ):
<manifest xlmns:android...>
...
<uses-permission android:name="android.permission.INTERNET" />
<application ...
</manifest>
