Directory Structure


Keeping projects organized can be difficult when there are a lot of moving parts.

Nylo tries to solve this with a simple project structure.

App Directories

All the app directories are listed inside the lib directory where your main.dart file runs.

  • app this folder includes any files relating to models, controllers and networking.

    • controllers Include your controllers here for your Widget pages.
    • models Create your model classes here.
    • networking Add any networking classes here for managing APIs or fetching data from the internet.
  • config this folder includes configuration files like for the theme or anything else you need.

  • resources this folder includes any files that are key components for your users UI experience like pages, widgets and themes.

    • pages Include your Widgets here that you will use as Page's in your project. E.g. home_page.dart.
    • themes By default we include two themes here but you can add more if your project needs to support more.
    • widgets Any widgets you need to create can be inserted here like a date_picker_widget.dart file.
  • routes this folder includes any files relating to models, controllers and networking.

    • router.dart contains the router for your application.

Public assets

All public assets can be found in public/assets. This directory is commonly used for images, fonts and more files that you may want to include in your project.

{info} It's important to add any new files into the pubspec.yaml file too.

  • app_icon This is used for generating app_icons for the project.
  • images Include any images here in this directory.
  • fonts Add any custom fonts here.

Retrieving an image asset

To get a image asset you can use getImageAsset(String key)

  height: 50,
  width: 50,

In this example, our public/assets/images/ directory has one file nylo_logo.png.

  • public/assets/images/nylo_logo.png

Retrieving a public asset

You can get any public asset using getPublicAsset(String key)

_controller = VideoPlayerController.asset(
  ..initialize().then((_) {

    setState(() {});

In this example, our public/assets/videos/ directory has one file intro.mp4.

  • public/assets/images/intro.mp4
