flutter_tflite VS Manji

For imageMean and imageStd, looking at the android implementation, we can see that these are passed along from dart to java eventually used at this point. Looking at the rest of this method, we can see this is in the context of converting the image data pixel by pixel into a bytearray that is eventually fed into the android tensorflow library. The actual conversion of pixel to bytearray is done by looking at the pixel RGB values separately and subtracting the mean then dividing by the std. This is meant to normalize your input data into "reasonable" data for your model.

Also a kanji learning app if anybody is interested: https://github.com/Livinglist/Manji

depends on what kinda specialization you are interested in, at least for me it’s mobile app development. I have been making apps since college, I was interested in Japanese language so I made a kanji learning app [0], then because I’m a bodybuilder, I made a workout log app [1], recently because I started reading hacker news, I made a Hacker News reader [2]. I learnt a lot from the process, from architecture, design pattern to code quality control. I would say learning is the key, usefulness is secondary.

I wrote a app for learning Japanese kanji when I was in college learning Flutter, I didn’t have any experience working on real world projects and barely have any knowledge of design pattern, architecture, clean code etc… I was young and naive, but had passion, so I started collecting data using scrappers I wrote in Python, organized them into a SQLite database, put a lot of example sentences and vocabulary on Firebase, then made an app using Flutter. I gradually added more features into the app after I released the first version, things like handwritten kanji recognition using Tensorflow lite and image text extraction using Google OCR api… I learned a lot, and by a lot, I mean a lot lot of stuff from making this app. The app is functioning just fine but the code is ugly as hell…for example attributes in data model classes are not final, doesn’t support dependency injection, etc….

After I started working, I learned a lot about how to write clean code and I always wanted to refactor/rewrite the whole app which gonna take a lot of effort and time of course. But every time I sat down, opened the old codebase, I hesitated, thought about it and told myself that it wasn’t worth it then continued my life.

do you have any personal project you always wanted to refactor/rewrite but still haven’t done or probably never will do so?

if you are interested, you can come see and compare the code of the kanji app and a new app I wrote recently:

Same here, I used to develop apps for Windows Phone back in 2014... then after I got into college, there was UWP, I made Japanese dictionary using it: [Kanjirin](https://www.microsoft.com/en-us/p/kanjirin/9pfwxjr41x4d?activetab=pivot:overviewtab), then I started learning Flutter, Dart was really easy to pick up, syntax is quite similar to C#, and I think what you need to practice on is state management and learn about widgets and useful thrid party packages. I made many mistakes when I was making my first flutter app - [Manji](https://github.com/Livinglist/Manji), but at least it got me my first Flutter related job. Here is my latest app using best practices if you are interested: [Hacki - Hacker News reader](https://github.com/Livinglist/Hacki)
