Building a CRUD Application with Flutter and Django: Introducing NoteTodo

---

Introduction

Flutter and Django, when combined, can produce powerful applications. In this article, we'll explore the intricacies of building a CRUD application named NoteTodo, which is a testament to this combination's capabilities.

Why Flutter and Django?

Flutter:

• Cross-Platform: Flutter's single codebase runs on both iOS and Android.

• Rich UI: With Flutter's widget-based architecture, creating interactive UIs is a breeze.

• Performance: Flutter's Dart code compiles to native ARM, ensuring optimal performance.

Django:

• DRY Principle: Django's emphasis on the DRY (Don't Repeat Yourself) principle ensures code reusability.

• Admin Interface: Django's built-in admin interface simplifies data management.

• Security: Django is equipped with out-of-the-box security features.

NoteTodo: A Glimpse

NoteTodo allows users to create, read, update, and delete notes. It's a demonstration of how Flutter's frontend can seamlessly integrate with a Django backend.

Setting Up NoteTodo

Prerequisites

• Flutter SDK

• Python 3.x

• Django

Installation & Setup

1. Clone the Repository

    git clone https://github.com/SalamiTech/note_todo.git
   

2. Backend Setup Navigate to the backend directory, install dependencies, and start the Django server.

    cd note_todo/notes_backend
    pip install -r requirements.txt
    python manage.py runserver
   

3. Frontend Setup Navigate to the frontend directory, fetch Flutter dependencies, and launch the app.

    cd ../notes_frontend
    flutter pub get
    flutter run
   

Diving Deeper: How It Works

The Backend

Django, combined with the Django Rest Framework, serves as the robust backend. Here's a glimpse of the Note model:

class Note(models.Model):
    id = models.AutoField(primary_key=True)
    body = models.TextField()

Endpoints are defined for various CRUD operations:

urlpatterns = [
    path('notes/', views.getNotes),
    path('notes/create/', views.createNote),
    ...
]

The Frontend

Flutter's UI is defined using a widget-based architecture. The main screen displays a list of notes:

ListView.builder(
    itemCount: notes.length,
    itemBuilder: (BuildContext context, int index) {
        return ListTile(
            title: Text(notes[index].note),
            ...
        );
    },
)

To communicate with the Django backend, HTTP requests are made:

http.Client client = http.Client();
final response = await client.get(Uri.parse(ApiUrls.getNotes));

Contributing to NoteTodo

NoteTodo is open-source and thrives on community contributions. Whether it's bug fixes, UI enhancements, or feature additions, every contribution counts. For guidelines, refer to Here.
