Building a Flutter Website: A Step-by-Step Guide

Glad you found this article where I will walk you through the process of building a Flutter website, focusing on easy responsive layouts and efficient form handling. To achieve this, we will leverage the Stacked framework, a meta-framework that provides opinionated production patterns for Flutter applications. Welcome to this website, I am Jonathan Izuchukwu known to many as SunshineIHCTS, without further introduction let us proceed with the actual topic.

Setup: Installing Stacked CLI and Creating a Flutter Web Project

To kick things off, let us set up our Flutter website. Follow these steps:

1. Install the Stacked CLI: pub global activate stacked_cli
2. Create a Flutter web project using the dedicated web template: stacked create app <your_project_name> --template=web 

Now that our project is set up, let us handle the responsive UI and layout.

Flutter Web Responsive UI Overview

1. Responsive Layouts with Stacked: To demonstrate responsive layouts, we will use the Stacked framework's ScreenTypeLayoutBuilder. This widget allows us to build different UIs based on the current screen size (mobile, tablet, desktop). Run the app with the following command: flutter run -d chrome Resize your Chrome window to observe how the UI adapts between desktop, tablet, and mobile views.

2. Building the Desktop UI: Now, let us focus on building the desktop UI. Modify the homeview.desktop.dart file, structuring the UI components and utilizing the Stacked framework.You can write UI code to create a desktop UI with various widgets, styles, and colors.

3. Creating a Flutter Website UI: Refine the UI by setting background colors, centering content, restricting content width, and incorporating the Google Fonts package for styling. Finally, add an image to the right side of the view using a ClipRRect widget with a specified border radius and an image asset.

Flutter Responsive Layouts

With the desktop UI in place, let us adapt it for mobile devices. Refactor each widget into its own file for reuse and organize them in a new folder called widgets. Create a mobile layout (homeview.mobile.dart) using a ListView to achieve a single-column design. Adjust widget sizes and layouts for optimal responsiveness.

Flutter Web Form Setup

Now, let us implement a form to capture the user's email. Stacked simplifies form handling with a code generation approach.

1. Use the @FormTextField annotation to specify the form text field name.
2. Extend the generated form mixin.
3. Enable two-way binding for automatic synchronization.

Generate the form code using stack generate and update the view model to extend FormViewModel. Implement a function to capture the email and show it in a dialog.

Flutter Web Form UI Binding

Connect the form to the UI by using a text editing controller for the text field. Update the layout widgets to accept and pass the controller to the input field widget. Invoke the captureEmail function when the notify button is tapped. Run stack generate to update the generated code and ensure the form works seamlessly with the UI.

Deploying the Flutter Website

To deploy the app, we will use Firebase hosting and the follow the processes I will list below:

1. Install Firebase tools: npm install -g firebase-tools
2. Initialize Firebase: firebase init
3. Build the Flutter web app: flutter build web
4. Deploy to Firebase: firebase deploy --only hosting

Your Flutter website will be live and ready for users to interact with when you are done. Feel free to explore additional features, enhance styling, or expand functionality based on your project requirements. You can share more insights in the comments section below.
