Plugin wrapper for the Polar SDK

Note

This is an unofficial wrapper for the Polar SDK. For any questions regarding the underlying SDKs or Polar devices in general, please see the official repository.

Getting Started

Android

android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.BLUETOOTH_SCAN" android:usesPermissionFlags="neverForLocation" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" android:maxSdkVersion="30" />

If you use BLUETOOTH_SCAN to determine location, remove android:usesPermissionFlags="neverForLocation"

If you use location services in your app, remove android:maxSdkVersion="30" from the location permission tags

iOS

Change the deployment target in Xcode to iOS 14+

Podfile:

platform :ios, '14.0'

Info.plist:

<key>NSBluetoothAlwaysUsageDescription</key>
<string>Used to connect to Polar devices</string>
<key>NSBluetoothPeripheralUsageDescription</key>
<string>Used to connect to Polar devices</string>
<key>UIBackgroundModes</key>
<array>
  <string>bluetooth-central</string>
</array>

Usage

import 'package:flutter/foundation.dart';
import 'package:polar/polar.dart';

const identifier = '1C709B20';
final polar = Polar();

void example() {
  polar.connectToDevice(identifier);
  streamWhenReady();
}

void streamWhenReady() async {
  await polar.sdkFeatureReady.firstWhere(
    (e) =>
        e.identifier == identifier &&
        e.feature == PolarSdkFeature.onlineStreaming,
  );
  final availabletypes =
      await polar.getAvailableOnlineStreamDataTypes(identifier);

  debugPrint('available types: $availabletypes');

  if (availabletypes.contains(PolarDataType.hr)) {
    polar
        .startHrStreaming(identifier)
        .listen((e) => debugPrint('HR data received'));
  }
  if (availabletypes.contains(PolarDataType.ecg)) {
    polar
        .startEcgStreaming(identifier)
        .listen((e) => debugPrint('ECG data received'));
  }
  if (availabletypes.contains(PolarDataType.acc)) {
    polar
        .startAccStreaming(identifier)
        .listen((e) => debugPrint('ACC data received'));
  }
}
