Ecommerce Mobile App with Flutter: Explained [+FAQs]

Ecommerce Mobile App with Flutter is creating mobile applications for online shopping and transactional purposes using the Flutter framework.

Flutter, the open-source UI software development kit, has gained immense popularity due to its ability to build high-performance mobile apps for both iOS and Android platforms. 

Flutter for eCommerce

There are several reasons why you might choose Flutter for ecommerce app development:

  • Fast development: Flutter’s new reload feature allows developers to quickly and easily test and implement changs, reducing the time it takes to build and deploy an app.
  • Cost-effective: Because Flutter allows for the development of Android and iOS apps using a single codebase, it can be more cost-effective than developing separate apps for each platform.
  • Good performance: Flutter apps are known for their smooth and responsive performance, essential for providing a good user experience.
  • Customizable: Flutter provides a wide range of customizable widgets and tools, allowing developers to create a unique and visually appealing app.
  • Strong community support: Flutter has a robust and active community of developers, making it easier to find support and resources when building an app.

Key Features and Benefits of Flutter

  • Open-Source: Flutter is a free and open-source framework for developing mobile applications.
  • Cross-platform: This feature allows Flutter to write the code once, maintain it, and run it on different platforms. It saves the time, effort, and money of the developers.
  • Hot Reload: Whenever the developer edits/changes the code, these changes can be seen instantaneously with Hot Reload. It means the changes are immediately visible in the app itself. It is a handy feature that allows developers to fix the bugs instantly.
  • Accessible Native Features and SDKs: This feature allows an easy app development process through Flutter’s native code, third-party integration, and platform APIs. Thus, we can easily access the SDKs on both platforms.
  • Minimal code: Flutter app is developed by Dart programming language, which uses JIT and AOT compilation to improve the overall start-up time and functioning and accelerate the performance. JIT enhances the development system and refreshes the UI without putting extra effort into building a new one.
  • Widgets: The Flutter framework offers widgets capable of developing customizable specific designs. Most importantly, Flutter has two sets of widgets: Material Design and Cupertino widgets help to provide a glitch-free experience on all platforms.

How Flutter Works

The app development using Flutter revolves around the combination of widgets. 

  • Flutter provides different types of widgets for aspects like structure (a menu or button), styling (a font or color scheme), layout (padding), and others. Using these widgets, you can easily craft the entire UI of the mobile app.
  • These are Flutter-developed widgets, and due to it being an open-source platform, any Flutter developer can use these widgets. 
  • Also, developers have the freedom to create their own widgets.
  • When utilizing JavaScript Bridge to compile programming languages for different platforms, it is common to encounter performance issues compared to the alternative frameworks.
  • However, this is not the issue with Flutter because it comes with reactive-style views and employs Dart for writing apps.
  • In terms of compiling Dart, it automatically compiles ahead of time (AOT) into the native code for different platforms without using JavaScript bridge. 
  • Since it gets compiled to native code ahead of time, the app startup time automatically scaled up to the next level.

Flutter is the only cross-platform mobile app development framework with a reactive view without the use of JavaScript. This is the reason which pulls a majority of developers towards cross-platform app development using Flutter. You can hire Flutter app developers to create visually amazing, native-performance apps for both platforms.

Building User Interfaces with Flutter Widgets

Flutter Widgets

Flutter provides a wide range of widgets that serve as the building blocks for creating user interfaces in your mobile apps. Widgets are the core elements of the Flutter framework, representing everything from buttons and text inputs to complex layouts and animations. 

Exploring the Widget Hierarchy:

  • In Flutter, widgets are organized in a hierarchical structure, forming a tree-like representation called the widget tree. 
  • At the root of the tree is the MaterialApp or CupertinoApp widget, which defines the overall configuration and theme for your app. 
  • You can nest various widgets to create your desired user interface from there. Widgets have two categories: StatelessWidget and StatefulWidget. 
  • StatelessWidget represents immutable widgets that do not change over time, while StatefulWidget represents widgets that can dynamically change their state and appearance.

The below image is a simple visual representation of the widget tree.

Creating Responsive Layouts with Rows, Columns, and Containers

One of the main aspects of building user interfaces is creating responsive layouts that adapt to different screen sizes and orientations. 

  • Flutter provides several widgets that enable flexible and responsive layouts.
  • Rows and columns are fundamental widgets that allow you to arrange child widgets horizontally or vertically. 
  • You can nest rows and columns within each other to create complex layouts.
  • The Container widget is a versatile widget, that serves the purpose of styling and positioning child widgets in various ways.
  • It sets the properties like margin, padding, alignment, and background color.
  • You can achieve responsive and adaptive layouts for your app by utilizing rows, columns, and containers.
  • You can specify constraints, such as minimum and maximum sizes, to ensure the UI elements are displayed correctly across various devices. 
  • Flutter also provides additional layout widgets like Expanded and Flexible, which help distribute available space among child widgets efficiently.

Managing State in Flutter

What is the State?

The active tone of the sentence would be:

  • You can read a state when building the widget, which may change or modify throughout the lifetime of the app.
  • If you want to change your widget, you need to update the state object, which can be done by using the setState() function available for Stateful widgets. 
  • The setState() function allows us to set the properties of the state object that triggers a redraw of the UI.

State management is one of the most popular and necessary processes in the lifecycle of an application. According to official documentation, Flutter is declarative. It means Flutter builds its UI by reflecting the current state of your app.

Let us take a simple example to understand the concept of state management. 

  • Suppose you have created a list of customers or products in your app. 
  • Now, assume you have added a new customer or product dynamically to that list. 
  • Then, refresh the list to view the newly added item in the record. 
  • Remember to refresh the list whenever you add a new item to the record. 
  • This type of programming requires state management to handle such a situation to improve performance. 
  • Because the state gets refreshed every time you change or update the same.

State Management Approaches


  • The simplest form of state management in Flutter is the setState method. 
  • This approach is suitable for small to medium-sized apps with limited state requirements. 
  • When the state of a widget changes, calling setState triggers a rebuild of the widget and its descendants, allowing you to update the UI based on the new state.


  • Riverpod is a state management library for Flutter that provides a more scalable and organized approach to managing states. 
  • It follows the principles of provider-based dependency injection and encourages a separation of concerns in your app. 
  • With Riverpod, you can define providers that encapsulate your app’s state and easily access and update that state from different parts of your app.

BLoC (Business Logic Component)

  • BLoC is another popular state management pattern in Flutter. 
  • It separates the presentation layer from the business logic and state management. 
  • With BLoC, you create a set of classes that handle the app’s state and business logic independently of the UI components. 
  • BLoC uses streams to communicate between the business logic layer and UI layer, ensuring a reactive and decoupled architecture.

Implementing State Management in Your App

To implement state management in your Flutter app, choose an approach that best suits your project’s requirements.

  • If your app has minimal state and doesn’t require complex logic, setState can be a viable option. 
  • Consider using libraries like Riverpod or BLoC for more organized and scalable state management for medium to large-scale apps.
  • To initiate any state management approach, define your app’s state variables, create appropriate providers or BLoCs, and use the provided widgets or streams to access and modify the state. 
  • It is essential to design your state management architecture carefully to ensure efficient and maintainable code.

Navigation and Routing in Flutter

Navigation and routing, fundamental concepts in mobile applications, enable users to enable transition between various pages easily. Every mobile application comprises multiple screens dedicated to presenting diverse information types.

  • For example, an app can have a screen that contains various products. When the user taps on that product, it will give you the product details.
  • In Flutter, the screens and pages are known as routes, and these routes are just a widget. 
  • In Android, a route is similar to an Activity, and in iOS, it is equivalent to a ViewController.
  • In any mobile app, navigating to different pages defines the application’s workflow, and the way to handle the navigation is known as routing. 
  • Flutter provides a routing class MaterialPageRoute and two methods Navigator.push() and Navigator.pop() shows how to navigate between two routes. 

The following steps are required to start navigation in your application.

Step 1: First, you need to create two routes.

Step 2: Navigate to one route from another route by using the Navigator.push() method.

Step 3: Finally, navigate to the first route using the Navigator.pop() method.
