Camulator App
Camulator is a Calculator Application, but with camera!
this app is for those of you that have a difficulties when buy something on market, but your hands is full of stuffs, so instead of open your calculator, use this Camulator to calculate with camera, do not need a lot of hands and gestures, just point out on the price of the product, and voila!
In this project, i use Riverpod as my State Management. for details you can see here.
The challenges that i've experienced is:
- Create a library by myself
i created Viewfinder Widget (not published in pub.dev yet) which i never create before.
this widget is like photomath app, the purpose of this widget is to crop the image, but before the image takken.
the challenge is, i have to find the reference first, and then i code it, there's a lot of trial and error to build this widget.
- Research and Technical Debt.
so, this part that use a lot of time and think!
when i buy some food for the monthly expensess, i go to the market, and think, if i have an app that can calculate with camera, it would be life savings!
then i go to home, and then research it, but unfortunately, in flutter, not much reference to build this app (with one source).
so, this is what i do, i search for OCR in Flutter, and then i search how to build Viewfinder widget, and then i have to think what should i do to calculate the number but with the list.
with research and deployment, finally this app has done to complete the MVP!
To see what features I made, you can see here
- Challenges for myself
i created the Flutask App, there's a lot of stars and forks that i've got, but that 2 years project, i did not continued at all, because of i have a lot of things to do in real life (because i still 17 y.o haha, there's an examination in school, im sorry...).
so, this time, with the new project, i challenge myself to finish what i've started. and voila!!
I use google_ml_kit_text_recognition for my OCR in Flutter. To see what Dependencies I created, you can see here.
Clone or Download and Open it into Android Studio, VSCode, or Other IDE / Text Editor
