Flutter plugin for scanning and transmit as beacon (iBeacon) on Android and iOS.

Flutter Beacon #

Pub GitHub Build Coverage Status FOSSA Status codecov

Flutter plugin to work with iBeacons.

An hybrid iBeacon scanner and transmitter SDK for Flutter plugin. Supports Android API 18+ and iOS 8+.

Features:

  • Automatic permission management
  • Ranging iBeacons
  • Monitoring iBeacons
  • Transmit as iBeacon

Installation #

Add to pubspec.yaml:

dependencies:
  flutter_beacon: latest

Setup specific for Android #

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>
  <!-- Always -->
  <!-- for iOS 11 + -->
  <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
  <string>Reason why app needs location</string>
  <!-- for iOS 9/10 -->
  <key>NSLocationAlwaysUsageDescription</key>
  <string>Reason why app needs location</string>
  <!-- Bluetooth Privacy -->
  <!-- for iOS 13 + -->
  <key>NSBluetoothAlwaysUsageDescription</key>
  <string>Reason why app needs bluetooth</string>
</dict>

iOS Troubleshooting #

  • Example code works properly only on physical device (bluetooth on simulator is disabled)
  • How to deploy flutter app on iOS device Instruction
  • If example code don't works on device (beacons not appear), please make sure that you have enabled
    Location and Bluetooth (Settings -> Flutter Beacon)

How-to #

Ranging APIs are designed as reactive streams.

  • The first subscription to the stream will start the ranging

Initializing Library #

try {
  // if you want to manage manual checking about the required permissions
  await flutterBeacon.initializeScanning;
  
  // or if you want to include automatic checking permission
  await flutterBeacon.initializeAndCheckScanning;
} on PlatformException catch(e) {
  // library failed to initialize, check code and message
}

Ranging beacons #

final regions = <Region>[];

if (Platform.isIOS) {
  // iOS platform, at least set identifier and proximityUUID for region scanning
  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'));
}

// to start ranging beacons
_streamRanging = 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
});

// to stop ranging beacons
_streamRanging.cancel();

Monitoring beacons #

final regions = <Region>[];

if (Platform.isIOS) {
  // iOS platform, at least set identifier and proximityUUID for region scanning
  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'));
}

// to start monitoring beacons
_streamMonitoring = flutterBeacon.monitoring(regions).listen((MonitoringResult result) {
  // result contains a region, event type and event state
});

// to stop monitoring beacons
_streamMonitoring.cancel();
