Overview

Introduction

HealthyWear is an IoT flutter application developed for the Android/iOS devices to streaming and capturing various health data from MetaWear (MetaMotions S) sensors, HBand, and Sensoria Smart Socks wearables. It provides dual-device functionality and is particularly focused on offering real-time feedback on physical activities, aiding in enhancing doctors diagnosis and patient treatment process. The app collects, stores, and transmits real-time vital signs and physical activity data to a server. This enables doctors to remotely keep track of their patients’ health, making it an essential tool in the management of their patients.

Features

MetaWear Integration: Connects to MetaWear sensors worn on each hand to monitor and record movements .
HBand Integration: Utilizes the HBand to track heart rate ,spo2 and blood pressure and providing vital health metrics.
Sensoria Smart Socks Integration: To incorporate data collection from smart socks for comprehensive foot movement analysis.
Data Management: Buffers and writting the data locally before sending it to the server, ensuring efficient transmission and minimal loss.
Doctor Dashboard: A server-side interface (not included in this repository) where doctors can view and analyze patient data.

Getting Started

Prerequisites

Flutter SDK(latest version recommended) ( https://docs.flutter.dev/get-started/install )
Android Studio and Xcode for platform-specific SDKs ( https://developer.android.com/studio/install )
Access to the required hardware (MetaWear sensors, HBand, Sensoria Smart Socks)

Installation (flutter)

Install Flutter SDK

Download Flutter:
- Visit the Flutter installation page.
- Download the latest stable Flutter SDK for macOS.
Extract Flutter:
- Extract the downloaded zip file and move the flutter folder to your desired installation location (e.g., ~/flutter).

- Add Flutter to your path permanently:
  - Open or create the $HOME/.zshrc file with a text editor like Nano:
    nano $HOME/.zshrc
  - Add the following line and replace [PATH_TO_FLUTTER_GIT_DIRECTORY] with the actual path to your Flutter SDK:
    export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin"
  - Save and exit the editor. Apply the changes by running:
    source $HOME/.zshrc
Run Flutter Doctor:
- Check for any dependencies you might need to install to complete the setup:
```
flutter doctor
```

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
```
- Agree to the terms of service when prompted.

3. Open the iOS folder with Xcode

Navigate to the iOS Folder:
- Open the iOS subfolder in your project:
```
open ios/Runner.xcworkspace
```
- This command opens the project in Xcode. If the project does not open, make sure you are in the correct directory and that the project includes an ios/Runner.xcworkspace file.

4. Run the App

Connect an iOS Device :
- Connect your iPhone via USB and trust the computer.
Configure Signing:
- In Xcode, navigate to the project settings by selecting the Runner from the Project Navigator.
- Click on the Signing & Capabilities tab.
- Choose your Team under the Team dropdown. You may need to add your Apple ID in Xcode > Preferences > Accounts if you haven’t already.
- Ensure that the Bundle Identifier is unique and matches your provisioning profile if you are preparing for distribution.
- Xcode may prompt you to fix issues related to provisioning profiles; allow it to do so if required.
Run the App:
- Click the Play button in Xcode or use the keyboard shortcut Cmd + R to build and run the app.
- The app should compile and then run on your selected device or simulator.

5. Troubleshooting Common Issues

Dependency Errors:
- If you encounter errors related to missing packages or dependencies, return to the terminal in your project directory and run:
```
flutter pub get
```
- Then try building the project again.
Build Errors:
- For errors during the build process, ensure all Xcode updates are installed. Check for any error messages in Xcode’s console that might indicate what needs to be addressed.
- Consider running flutter clean in your project directory to clean the build and then try running the app again:
```
flutter clean
flutter run
```
