Nothing.

Setup specific for iOS

In order to use beacons related features, apps are required to ask the location permission. It's a two step process:

1. Declare the permission the app requires in configuration files
2. Request the permission to the user when app is running (the plugin can handle this automatically)

The needed permissions in iOS is when in use.

For more details about what you can do with each permission, see:
https://developer.apple.com/documentation/corelocation/choosing_the_authorization_level_for_location_services

Permission must be declared in ios/Runner/Info.plist:

<dict>
  <!-- When in use -->
  <key>NSLocationWhenInUseUsageDescription</key>
  <string>Reason why app needs location</string>
  ...
</dict>

How-to

Ranging APIs are designed as reactive streams.

• The first subscription to the stream will start the ranging

Initializing Library

try {
  await flutterBeacon.initializeScanning;
} on PlatformException {
  // library failed to initialize, check code and message
}

Ranging beacons

final regions = <Region>[];

if (Platform.isIOS) {
  regions.add(Region(
      identifier: 'Apple Airlocate',
      proximityUUID: 'E2C56DB5-DFFB-48D2-B060-D0F5A71096E0'));
} else {
  // android platform, it can ranging out of beacon that filter all of Proximity UUID
  regions.add(Region(identifier: 'com.beacon'));
}

flutterBeacon.ranging(regions).listen((RangingResult result) {
  // result contains a region and list of beacons found
  // list can be empty if no matching beacons were found in range
});

• iOS uses native iOS CoreLocation
