如何通过Flutter在Google Fit上注册跑步

dependencies:
  google_sign_in: ^5.0.0
  googleapis: ^0.54.0

import 'package:googleapis/fitness/v1.dart';
import 'package:googleapis_auth/auth_io.dart';

Future<void> requestFitPermissions() async {
  final scopes = [FitnessApi.FitnessActivityReadScope];
  final client = await clientViaUserConsent(
    ClientId('<YOUR_CLIENT_ID>', '<YOUR_CLIENT_SECRET>'),
    scopes,
    prompt,
  );
  // 在这里可以使用client来访问Google Fit API
}

import 'package:googleapis/fitness/v1.dart';
import 'package:googleapis_auth/auth_io.dart';

Future<void> registerRunningActivity() async {
  final scopes = [FitnessApi.FitnessActivityWriteScope];
  final client = await clientViaUserConsent(
    ClientId('<YOUR_CLIENT_ID>', '<YOUR_CLIENT_SECRET>'),
    scopes,
    prompt,
  );

  final activity = Session();
  activity.activityType = 'running';
  activity.startTimeMillis = DateTime.now().millisecondsSinceEpoch;
  activity.endTimeMillis = DateTime.now().millisecondsSinceEpoch + 3600000; // 结束时间为开始时间加1小时

  final request = Dataset();
  request.session = activity;

  final fitnessApi = FitnessApi(client);
  await fitnessApi.users.dataSources.datasets.patch(
    PatchDatasetRequest()..dataSourceId = 'derived:com.google.step_count.delta:com.google.android.gms:estimated_steps',
    'me',
    'derived:com.google.step_count.delta:com.google.android.gms:estimated_steps',
    request,
  );
}
