Describe the bug

It's not a bug, but a help request. I can't find the way to detect if user has Google Fit installed, is there any method integrated on the library?

@RTsosssoldi I'm using the following package to check if Google Fit is installed in the device

import 'package:device_apps/device_apps.dart';

Add the permission in the manifest file

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" />

Use the following snippet

Future<bool> isGoogleFitInstalled() async {
    try {
      final value =
          await DeviceApps.isAppInstalled('com.google.android.apps.fitness');
      return value;
    } catch (e) {
      return false;
    }
  }
