A Flutter package to make for iHealth.

Getting started

Step 1: Install IHealth

To install iheath, simply add iheath: to the dependencies of your pubspec.yaml file:

    iheath: #latest version

Step 1a: (for Android only) Modify you manifest

iheath uses flutter_web_auth_2_2 to let you authenticate to Fitbit. In Android, you need to add these lines of code to your android/app/src/main/AndroidManifest.xml file:

<activity android:name="com.linusu.flutter_web_auth_2_2.CallbackActivity"
      <intent-filter android:label="flutter_web_auth_2_2">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="CALLBACK_SCHEME" />

and change CALLBACK_SCHEME with your callback scheme (in the test example below this will be example)

Step 1b: (for Android only) Increase the minimum Android SDK version

iheath uses flutter_secure_storage to securely store the Fitbit tokens. Since flutter_secure_storage requires that minimum Android SDK version is 18, you need to change the default minimum sdk version to 18 or above. To do so, open android/app/build.gradle, locate this snippet of code:

defaultConfig {
        applicationId "your.app.id"
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName

and change minSdkVersion to 18 or above, e.g.,:

defaultConfig {
        applicationId "your.app.id"
        minSdkVersion 18
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName

Step 1(Android)

iheath uses flutter_web_auth_2 to let you authenticate to Fitbit. In order to let it work correcty please be sure that your emulator or your physical device is using Chrome, Opera, or Firefox as default web browser.

App authentication

STEP 1 (create auth url)

    final IHealthAuthUrl iHealthAuthUrl = IHealthAuthUrl(
                          clientSecret: clientSecret,
                          clientId: clientId,
                          redirectUri: AppConstant.fitibitRedirectUri,
                          credencial: null);

STEP 2 (authenticate)

   _iHealthCredencial = await IHealthService.authorize(
authUrl: iHealthAuthUrl,
redirectScheme: redirectScheme);

Fetch Bp count

Create bpUrl

 final IHealthDataUrl iHealthBpUrl = IHealthDataUrl(
                      sc: scBp,
                      sv: svBp,
                      credencial: _iHealthCredencial,
                      redirectUrl: AppConstant.fitibitRedirectUri,
                      clientId: clientId,
                      clientSecret: clientSecret,


  final x = await IHealthService.getBpByUserId(
                        iHealthBpUrl: iHealthBpUrl, pageIndex: 1);
