I am trying to create an app about periodically fetching step data from Google Fit API and send that data to custom API. So far everything is ok and works fine while app is open. Then I wanted to make these things happen even if i kill the app.
For that, i used Flutter Foreground Task plugin and it is working fine. BUT when i try to call fetch health data function in foreground, plugin says "Authorization not granted.". I really don't know why is this happening and what i have to do. I am kinda new at Flutter and it is my first time doing a project like that.
Note: I did everything to setup Health Plugin. I got SHA1 key and added it to the Google API console etc. It is working fine when i use it in app. The problem is using it on foreground service method.
Foregorund Service Method (where i call the fetch health data method)
class FirstTaskHandler implements TaskHandler {
@override
Future<void> onStart(DateTime timestamp, SendPort? sendPort) async {
// You can use the getData function to get the data you saved.
final customData =
await FlutterForegroundTask.getData<String>(key: 'Steps');
print('Steps: $customData');
}
@override
Future<void> onEvent(DateTime timestamp, SendPort? sendPort) async {
// Send data to the main isolate.
GetHealthData().fetchHealthDataMethod(); //This is where i call health plugin to fetch steps data on foreground.
sendPort?.send(timestamp);
}
@override
Future<void> onDestroy(DateTime timestamp) async {
// You can use the clearAllData function to clear all the stored data.
await FlutterForegroundTask.clearAllData();
}
}
healthData.dart class (the place that i implement the fetch health data function)
class GetHealthData extends StatefulWidget {
const GetHealthData({Key? key}) : super(key: key);
fetchHealthDataMethod() => createState().fetchHealthData();
@override
_GetHealthDataState createState() => _GetHealthDataState();
}
class _GetHealthDataState extends State<GetHealthData> {
List<HealthDataPoint> _healthDataList = [];
var nickname;
@override
void initState() {
super.initState();
}
Future fetchHealthData() async {
SharedPreferences prefs = await SharedPreferences.getInstance();
var datasource = prefs.getInt('datasource');
if (prefs.getString("token") != null && datasource == 1) {
// get everything from midnight until now
DateTime current = DateTime.now();
DateTime dateFrom;
DateTime dateTo;
dateFrom = current.subtract(Duration(
hours: current.hour,
minutes: current.minute,
seconds: current.second,
milliseconds: current.millisecond,
));
dateTo = DateTime.now();
HealthFactory health = HealthFactory();
// define the types to get
List<HealthDataType> types = [
HealthDataType.STEPS,
];
// you MUST request access to the data types before reading them
bool accessWasGranted = await health.requestAuthorization(types);
int steps = 0;
if (accessWasGranted) {
try {
// fetch new data
List<HealthDataPoint> healthData =
await health.getHealthDataFromTypes(dateFrom, dateTo, types);
// save all the new data points
_healthDataList.addAll(healthData);
} catch (e) {
print("Caught exception in getHealthDataFromTypes: $e");
}
// filter out duplicates
_healthDataList = HealthFactory.removeDuplicates(_healthDataList);
SharedPreferences prefs = await SharedPreferences.getInstance();
// print the results
_healthDataList.forEach((x) {
print("Data point: $x");
steps += x.value.round();
Users.steps = steps;
TempData.tempSteps = steps;
prefs.setInt(('sharedSteps'), steps);
});
await FlutterForegroundTask.saveData(key: 'Steps', value: steps);
print("Steps: $steps");
} else {
print("Authorization not granted");
}
}
}
AND THE ERROR

I/flutter (18179): Authorization not granted
As you can see, fetching function works fine when it is called from initState. It can show the steps data and can print to the screen but when i call the same function from foreground, it says "Authorization not granted".
If you need more information please ask to me. Thanks for any advice and help already.
