FlutterFlow and HealthKit integration: Step-by-Step Guide 2024

• Open FlutterFlow and create a new project or open an existing one.
• Set up your UI and other required functionalities for your app.

• Ensure Xcode is installed on your macOS. HealthKit integration requires an iOS environment, which Xcode provides.
• Open Xcode and make sure it’s up to date.

• In FlutterFlow, go to “Settings” > “App Settings” > “Platforms” and click on iOS to download your Flutter project.
• Extract the downloaded zip file.
• Open the `.xcworkspace` file located inside the iOS folder of your project in Xcode.

• Select your project in the Xcode Project Navigator.
• Click on the `TARGETS` section and select your app target.
• Under the `Signing & Capabilities` tab, click the `+` button to add a new capability.
• Choose `HealthKit` from the list of available capabilities.

• Open the `pubspec.yaml` file in your Flutter project.
• Add the `health` package dependency:

dependencies:
  health: ^3.1.5  # Ensure to check for the latest version

• Run `flutter pub get` to install the new dependency.

• Modify the `Info.plist` file in your Xcode project to include HealthKit permissions.
• Add the following XML entries within the `` tag:

<key>NSHealthShareUsageDescription</key>
<string>We need access to your health data to provide better services.</string>
<key>NSHealthUpdateUsageDescription</key>
<string>We need access to update your health data to provide better services.</string>

• Open your preferred Dart file in your Flutter project, and import the `health` package.

import 'package:health/health.dart';

• Create methods for requesting permissions and fetching data:

// Include required imports
import 'package:health/health.dart';

// Create a HealthFactory instance
HealthFactory health = HealthFactory(useHealthKit: true);

// Required Health Data Types
final types = [
  HealthDataType.HEART\_RATE,
  HealthDataType.STEPS,
  HealthDataType.ACTIVE_ENERGY_BURNED,
  // Add more types as per your requirement
];

// Method to request permissions
Future<bool> requestPermissions() async {
  final requested = await health.requestAuthorization(types);
  return requested;
}

// Method to fetch data
Future<void> fetchHealthData() async {
  final now = DateTime.now();
  final yesterday = now.subtract(Duration(days: 1));

  final healthData = await health.getHealthDataFromTypes(yesterday, now, types);

  // Process your health data here
}

• Call the `requestPermissions` method when the app starts or at the appropriate point in your app's lifecycle.

@override
void initState() {
  super.initState();
  requestPermissions().then((requested) {
    if (requested) {
      fetchHealthData();
    } else {
      print('Permission denied');
    }
  });
}

• Based on the health data fetched, update your UI to display the relevant health information.
• Use FlutterFlow widgets to display this data elegantly.

• HealthKit functionalities can’t be tested on iOS simulators. Therefore, build and run your app on a physical iOS device.
• Connect your device, select it in Xcode, and hit the `Run` button.

• Ensure your app complies with Apple’s guidelines regarding HealthKit data usage.
• Test thoroughly and, once satisfied, submit your app to the App Store.
