samsung_health_handler 0.2.6

Helps to integrate flutter with the Samsung-health-app. The Samsung health app is must be installed to use this.

samsung_health_handler

This package is currently on development. So, if you want stability, i do not recommend you to use this.

Coverage

Currently, this package only supports step count data.
No iOS support.

StepCount payload

name	type	etc
stepCount	int
calorie	int	Cal
distance	double	meter
timestamp	int	millisecond
binningData	StepCountBinningDataType	Supports time(String - HH:mm), stepCount(int)

Installation

  samsung_health_handler: <latest-version>

Configuration

####Android Add in AndroidManifest.xml

<meta-data
    android:name="com.samsung.android.health.permission.read"
    android:value="com.samsung.health.step_count;com.samsung.shealth.step_daily_trend"
/>

Notice

Lifecycle

1. Set stream
2. initialize
3. dispose

Sample usage is on bottom.

Why initialize callback does not arrive when performs "Hot Restart"?

On hot restart, dispose method of stateful widget does not work. So, If you want to reinitialize SamsungHealthHandler, you must manually dispose and reinitialize.

Sample Usage

import 'package:flutter/material.dart';
import 'package:intl/intl.dart';
import 'package:samsung_health_handler/StepCountDataType.dart';
import 'package:samsung_health_handler/samsung_health_handler.dart';

void main() {
  Intl.defaultLocale = 'ko_KR';
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  Stream<StepCountDataType> stepStream = SamsungHealthHandler.stream;
  bool loading = true;

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_) async {
      await initialize();
    });
  }

  @override
  void dispose() {
    super.dispose();
    disposeSamsungHealth();
  }

  initialize() async {
    var isInitialized = await SamsungHealthHandler.initialize();
    if (isInitialized) {
      setState(() {
        loading = false;
      });
    }
  }

  disposeSamsungHealth() async {
    SamsungHealthHandler.dispose();
    setState(() {
      loading = true;
    });
  }

  @override
  Widget build(BuildContext context) {
