Everything you need to know to have a good flutter app structure.
Folder structure
Small-Medium apps
lib
Contains the primary folders and a few primary dart files like main.dart & localization.dart.
assets
Contains all external assets that are imported using the assets section of pubspec.yaml.
pages
Contains all the pages.
In small to medium apps you can have all the pages in this folder.
services
Contains view context independent app logic.
widgets
Contains global widgets.
In smaller apps it contains all the widgets.
Large apps
Larger apps may have more folders in lib.
here is two example extra folders that bigger projects may have:
themes
Your app is probably not going to have a hundred themes, if it does, create reusable themes.
plugins
It is not recommended to write platform plugin in your project.
If you have to write your own plugin, for testing purposes, write it in the plugins folder
then create a new flutter plugin project and migrate your code to there. if possible open source or
publish that plugin to pub.dev.
State management
Services
Service do not have modified constructors. They cannot depend on BuildContext.
