Building a shopping cart in Flutter

The blog post details the creation of a simple shopping cart application designed for an ecommerce platform, demonstrating the use of Flutter along with packages like SQFlite, SharedPreferences, and Provider to manage state and store data locally on a device. The application comprises two primary screens: a product screen displaying a list of fruits that users can add to a shopping cart, and a cart screen where users can view, modify, or remove items, with features allowing for the adjustment of item quantities and displaying the total price. The step-by-step process involves setting up dependencies, creating model classes for cart items, and implementing database and state management functionalities. The post emphasizes the use of a Provider class to separate UI logic from application logic and highlights the use of Consumer widgets to optimize UI updates. The article concludes with an acknowledgment of a contributor and a brief mention of LogRocket for error tracking, offering a practical example of building a UI with Flutter for a basic ecommerce shopping cart.
