JHen Tai

Abstract

1. Introduction

My first project With Flutter. I aim at getting familiar with Flutter during development. Devices I use include Android phone, Ipad and Windows computer. E-hentai apps I used before have several bugs, and I don't understand source code because I have no development experience with Android or ios, so I choose JHenTai to become my first Flutter Project.

refactored some codes for gallery page, reading page, download, etc. which are written at the beginning stage. I tried my best to extract the commonality between different page and style to reduce coupling, in order to benefit the development of new features. I would be very grateful if any kind of you could give me some advice on coding style, design patterns and anything related to Flutter development or participate in the development of JHenTai.

So updates for JHenTai will be less than previous, but I'll still handle bugs or issues in time。
