This is the code for "How to Build a Healthcare Startup" by Siraj Raval on Youtube

Overview

This is the code for this video on Youtube by Siraj Raval on "How to Build a Healthcare Startup". The app uses PoseNet to detect human poses and a text to speech engine to speak to you. This emulates the role of a Yoga instructor! This code is unfinished, but meant to give you a starting point and guide so that you can build a profitable business using it or a similar idea.

Dependencies

All of these can be downloaded in a single command, see below.

• PoseNet Model
• Tensorflow Lite
• Stripe
• RazorPay
• Flutter Text to Speech

Instructions

First install Flutter.

After download, from command line run this to install the dependencies

flutter packages get

Then run this command to run the app

flutter run

Alternatively you can open the app as a new flutter project in Android Studio after installing the Flutter plugin. See the video for instructions on how to do that.

TODO - please make a PR if you fix any of these

• Firebase is integrated, but it still needs to be properly wired up to the login and signup pages.
• Stripe and RazorPay are integrated, but each still need to be wired up to the Credit/Debit Card view i created.
• Generate some text everytime a pose is detected, not just on startup.
• Make the personal 0/10 score some meaningful metric, store it in Firebase.
• PoseNet is integrated, but still needs to be replaced by YogaNet.

Wait what's YogaNet?

this is YogaNet. This person retrained a neural network to detect yoga poses and outputted the result as a TFLite file in their /models folder. Notice how in this flutter app, there is space to import TF Lite models. Integrate the Yoga Model into the app by replacing the existing posenet model.

What does it mean to source bash?

I was watching Siraj in the YouTube video, and I was following along okay until about 26:12 when he says "you gotta source your bash and stuff." What does he mean by that? I am trying to run the flutter_realtime_detection-master from shaqian in my command prompt.

Add yoganet compatibility

When running yoganet model with the method runmodelonframe() it crashed

Yoganet integration

Hi my yoga net model is not working. I downloaded the YogAI model.tflite but when I press begin. It says "success" but nothing shows up and when I replace the called model in the PoseNet button on the signup screen, it just shows a standard camera. Any ideas?

White screen when running emulator or real device

Hi.
I have downloaded the repo but when i run it in my android studio ,v3.5, all i get in my emulator/real device is a white screen when opening the app and the console just says "E/BpSurfaceComposerClient(10222): Failed to transact (-1)
E/BpSurfaceComposerClient(10222): Failed to transact (-1)"
. I have the same problem with the flutter-realtime-detection-master by shaqian. Any help with this would be greatly appreciated.

Release Mode App Crash

Debug mode app run successfully but release mode app crash

( 4271): Program linking failed.

When clicking the Begin button, nothing happens except I get ( 4271): Program linking failed. in the console and it stays in the same screen. If I try the posenet button, I am able to see that the pose estimation is working (only dots without lines are shown)

License?

What is the license on this code?

How would one get rid of the payment system

I am trying to access the yoga part of the app, but want to remove the payment functionality. How should I edit the code?
