在 Flutter 中使用 Google 擬合 API

Question

我需要我的應用程序從 Google Fit 讀取步數。 我正在使用健康 3.05 package。 現在我復制了示例代碼以查看它是否有效，不幸的是它不是。 當然，我從這個包自述文件中完成了每一步。 我設置了 OAuth2 客戶端 ID，我更改了 gradle.properties 和 AndroidManifest.xml 我把<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION"/> . 但是，在運行應用程序后，我沒有獲得任何權限 window 並且當我單擊按鈕獲取數據時，我在控制台中收到錯誤“未授予授權”。 我應該怎么辦？ 謝謝

這是我從 package 示例中復制的代碼：

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:health/health.dart';

class DailyStepsScreen extends StatefulWidget {
  @override
  _DailyStepsScreenState createState() => _DailyStepsScreenState();
}

enum AppState {
  DATA_NOT_FETCHED,
  FETCHING_DATA,
  DATA_READY,
  NO_DATA,
  AUTH_NOT_GRANTED
}

class _DailyStepsScreenState extends State<DailyStepsScreen> {
  List<HealthDataPoint> _healthDataList = [];
  AppState _state = AppState.DATA_NOT_FETCHED;

  @override
  void initState() {
    super.initState();
  }


  Future<void> fetchData() async {
    /// Get everything from midnight until now
    DateTime startDate = DateTime(2020, 11, 07, 0, 0, 0);
    DateTime endDate = DateTime(2025, 11, 07, 23, 59, 59);

    HealthFactory health = HealthFactory();

    /// Define the types to get.
    List<HealthDataType> types = [
      HealthDataType.STEPS,
      HealthDataType.WEIGHT,
      HealthDataType.HEIGHT,
      HealthDataType.BLOOD_GLUCOSE,
      HealthDataType.DISTANCE_WALKING_RUNNING,
    ];

    setState(() => _state = AppState.FETCHING_DATA);

    /// 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(startDate, endDate, 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);

      /// Print the results
      _healthDataList.forEach((x) {
        print("Data point: $x");
        steps += x.value.round();
      });

      print("Steps: $steps");

      /// Update the UI to display the results
      setState(() {
        _state =
        _healthDataList.isEmpty ? AppState.NO_DATA : AppState.DATA_READY;
      });
    } else {
      print("Authorization not granted");
      setState(() => _state = AppState.DATA_NOT_FETCHED);
    }
  }

  Widget _contentFetchingData() {

  }
}

Answer 1

第 1 步使用health: 3.0.4

第 2 步正確設置 OAuth2 客戶端 ID，下載新的 google-service.json

第 3 步從 Android 10. 您必須添加ACTIVITY_RECOGNITION才能在AndroidManifest.xml中獲得 STEP Count 權限。

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

第 4 步然后使用permission_handler請求權限。

if (Platform.isAndroid) {
  final permissionStatus = Permission.activityRecognition.request();
  if (await permissionStatus.isDenied ||
      await permissionStatus.isPermanentlyDenied) {
    showToast(
        'activityRecognition permission required to fetch your steps count');
    return;
  }
}

Answer 2

終於解決了這個問題！

所以問題不在於我使用的版本 3.4.0 但仍然解決了問題

未授予授權。 並且卡在加載界面

卡在授權請求屏幕

當您創建 OAuth 2.0 同意屏幕時，請嘗試將至少 2 個 email 地址添加到“測試用戶”部分，並確保從該電子郵件登錄。

在測試用戶中添加 2 個 email 地址

之后，請確保從 Google 驗證您的應用程序，它會一直有效，直到您發布應用程序后測試您的應用程序，它才會有效

從 Google 驗證您的應用程序

最后結果

Answer 3

第 1 步使用健康：3.0.4

Step 2 添加權限 function

第 3 步在 initstate 中啟動您的 function
