Flutter is a powerful UI toolkit that allows developers to build natively compiled applications for mobile, web, and desktop from a single codebase. In this blog, we’ll guide you through setting up the Flutter Template, a project designed with clean architecture, responsive design, and various essential features like state management and widget testing. So, let’s get started!

Prerequisite Setup

Before diving into the Flutter Template, ensure your development environment is ready:

• Install Dart version 2.19.2 or greater.
• Install Flutter version 3 or greater.
• Follow the official guide to set up your Flutter environment based on your operating platform here.

Steps to Set Up the Project

Now that your pre-requisites are in place, follow these steps:

1. Clone the Repository

Start by cloning the repository:

git clone https://your-repo-link.git

2. Verify Flutter Installation

Ensure that Flutter is correctly installed by checking the version:

flutter --version

Expected output should resemble:

Flutter 3.x.x • channel stable

3. Install Derry as the Script Manager

Derry helps manage scripts more efficiently:

dart pub global activate derry

4. Install the Required Dependencies

Next, get all dependencies required for the project:

flutter pub get

5. Run Code Generations

This step helps generate boilerplate code required for the application:

derry generate all

6. Set Up Your API Key (Optional)

If you’re looking to implement weather search functionality, you would need an API key:

• Obtain the Open Weather API key from here.
• Update the .env files in the template with your API key.

Running the App

To launch the application, use the following command and specify the flavor:

derry launch dev

Understanding the Architecture

The architecture of this template facilitates separation of concerns, letting each layer function independently. Think of your application as a hotel:

• Presentation Layer: This acts like the lobby where guests interact with the staff (UI and state management).
• Domain Layer: This layer serves as the concierge, providing essential services and handling guest requests (business logic).
• Data Layer: Think of this as the backend, storing all information (database and external APIs).

Troubleshooting Common Issues

• If you encounter issues with variable refresh rates on Android, try using the flutter_displaymode package for optimal performance.
• For goldens mismatch across different OS, ensure that goldens are generated and tested on a single OS.
• If you face any setup issues, refer back to the commands for dependency management and environmental setup.
