Here is the core folder structure which flutter provides.
flutter-app/ |- android |- assets |- build |- ios |- lib |- test |- web
Here is the folder structure we have been using in this project
lib/app |- data/ |- modules/ |- routes.dart
Now, lets dive into the lib folder which has the main code for the application.
1- constants - All the application level constants are defined in this directory with-in their respective files. This directory contains the constants for `theme`, `api endpoints`, `preferences` etc. 2- modules - Contains the 3 different modules of the app. 3 - routes.dart — This file contains all the routes for your application.
This directory contains all the application level constants. A separate file is created for each type as shown in example below:
constants/ |- alerts.dart |- end_points.dart |- images.dart |- stylings.dart
Contains the 3 different modules of the appplication.
modules/ |- history/ |- home/ |- questions
Folders found in each module:
controllers - this is where the logic of the app is written. views - contains the ui of the module. providers — contains the network calls. models - contains the application's dynamic data structure
This file contains all the routes for your application.
routes/ |- app_pages.dart |- app_routes.dart
This is the starting point of the application. All the application level configurations are defined in this file i.e, theme, routes, title, orientation etc.
