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)) {
