Pixyway picture viewer Hello guys, today I'm proud to announce you that I have just released a Windows app that I made these lasts months. As almost all computer projects never see the light of day , I decided that one of my goal will be to publish it publicly. And today it's done! A brief history One of my prefered subject is image computing, photography and all the digital arts. I don't know if you remeber the Google software "Picasa" but I used to loved it for its simplicity and efficiency. Nowadays, Picasa is only a warm memory and is no more availble... The fact is that all software are transferred to the web :( For some it's justified but for a lot of other I still "don't understand" why... This is not the question of the day, but it made decide to implement a real desktop application that could be replace (even a little bit) my loved Google Picasa app :) It's how Pixyway viewer is borned !

There are many ways to add a background image to your pages, but the most common way is to use a BoxDecoration Widget. The BoxDecoration Widget is placed under a parent Container Widget (container.decoration). Then, you can customise the Image decoration using Assets images, Network images... Sample code (with an asset image): @ override Widget build ( BuildContext context ) { return GetBuilder < MainPageController >( id : 'mainpage' , init : MainPageController (), builder : ( vm ) => Scaffold ( body : Container ( width : double . infinity , height : double . infinity , decoration : const BoxDecoration ( image : DecorationImage ( image : AssetImage ( 'assets/images/dark_background2.jpg' ), fit : BoxFit . fill , )), child : SafeArea ( top : true , bottom : true , child : Container (

I'm sure, if you are a Flutter's developer, that you will need one day to get specific paths, for instance to store files, generate temporary files etc... Path_provider package For that I use the 'path_provider' package that has some helpers methods. For example: Future < Directory >   getApplicationDocumentsDirectory ( ) returns the documents directory. How to use it ? Directory tempDir = await getTemporaryDirectory(); String tempPath = tempDir.path; Directory appDocDir = await getApplicationDocumentsDirectory(); String appDocPath = appDocDir.path; Follow the links: Package:  https://pub.dev/packages/path_provider Package's documentation:  https://pub.dev/documentation/path_provider/latest/index.html

As applications are actually spread around the world, a common task to implement when developing your app (mobile, web or desktop), is to setup a multi-language option .  In Flutter, it can be done easily with the GetX Package (a useful package that provides a lot more services ! You should take a look if you don't know this package:  GetX package on pub.dev . The implementation steps are the following: 1-Add GetX package to your solution You can do it the traditional way you like. For instance with "Pub Assist" extension: Shift+CMD+P > Pub asssist: add/upgrade > get 2-Use a GetMaterialApp Important step, do not forget to use the GetMaterialApp classe instead of Flutter's MaterialApp: @ override Widget build ( BuildContext context ) { return GetMaterialApp ( 3-Add a translation file Next you have to add a class that will embed all your strings declaration / translations. This class must extends the GetX's Translation class. Here is an example:
