sfit_step_counter 0.0.9

Step Counter is a lightweight Flutter package that detects steps in real-time using the accelerometer via sensors_plus.

🏃 Step Counter

A lightweight Flutter package to help you count steps using the device's gyroscope and Kalman filtering. This package is a modern alternative to deprecated or unstable step tracking packages like health and pedometer, which often crash on certain devices.

Built with simplicity, performance, and compatibility in mind.

🚀 Features

• 📱 Step detection using sensors_plus

• 📊 Real-time step stream

• 🔁 Simple API: start(), stop(), reset()

• 🔥 Calculates:

  • Total steps
  • Calories burned
  • Walking speed (km/h)

• ⚙️ Lightweight Kalman filter for noise reduction

• ✅ No activity recognition dependency required

🧪 Usage

import 'package:sfit_step_counter/sfit_step_counter.dart';

final stepCounter = StepCounter();

await stepCounter.init(weightKg: 68, heightMeters: 1.72);

stepCounter.start();

stepCounter.stepStream.listen((steps) {
  print('Steps: $steps');
  print('Calories: ${stepCounter.caloriesBurned.toStringAsFixed(2)} kcal');
  print('Speed: ${stepCounter.walkingSpeedKmh.toStringAsFixed(2)} km/h');
});

🔐 Permissions

You’ll need to request the activity recognition permission:

import 'package:permission_handler/permission_handler.dart';

Future<void> requestPermissions() async {
  if (await Permission.activityRecognition.request().isGranted) {
    // Permission granted
  }
}
