Building applications with Flutter can be made easy and efficient using the BLoC (Business Logic Component) Pattern. In this guide, we will walk you through the process of creating a Flutter application using the Flutter Starter Kit that utilizes BLoC to handle network calls effectively. Let’s dive in!

What is the BLoC Pattern?

The BLoC Pattern helps manage the flow of data between the UI and the business logic in your applications. It allows you to separate your presentation layer from your business logic, making your code cleaner and easier to maintain.

Key Features of the Starter Kit

• Centralized management for application colors and constants
• Structured directories for organization:
  • api: Handles common API concerns.
  • blocs: Holds all BLoCs to manage data streams.
  • models: Represents the data structure.
  • repositories: Manages CRUD operations.
  • responses: Stores responses from API calls.
  • utils: Contains utility functions.
  • views: Manages UI components.
  • partials: Holds reusable widgets.
• Google AdMob and Firebase FCM ready
• Includes sample pages such as Splash Screen, Login, and Movies List demonstrating BLoC usage.

How to Get Started

To create your Flutter application based on this starter project, follow these steps:

1. Clone the repository:

   git clone git@github.com:lexxyungcarterflutter-starter-kit.git myapp

2. Open the folder in Android Studio.
3. Update the namespace of your project.
4. Edit your constants and styles in lib/utils/ as necessary.
5. Consider creating an env.dart file for secure storage of API keys.

Changing the Namespace of Your App

To rename your app’s namespace, follow these steps:

1. Ensure Android Studio has completed indexing.
2. In Project Viewer mode, expand the starterkit_android folder.
3. Right-click on the namespace (e.g., space) and select refactor to rename it.
4. Confirm that changes are made in AppManifest and all build files.

Building and Deploying Your App

Before you deploy your application, make sure to set environment settings appropriately.

For Local Development

• Update lib/utils/admob_constants.dart to set testing mode to true.
• Update lib/utils/constants.dart similarly.

For Production Development

• Switch back the testing mode in the above files to false.
• Ensure your correct Google Ad Units are set up in admob_constants.dart.

Troubleshooting

If you encounter issues during setup or running your app, consider the following:

• Ensure all file paths and constants are correctly set.
• Verify that dependencies in your pubspec.yaml file are correctly listed and up-to-date.
• Check for any missing or misnamed files based on the references in your code.
• Make sure you’re running the application in an appropriate environment (e.g., emulator or device).

Updating Your App’s Launcher Icon

To update the launcher icon for your application:

1. Create a logo of size 1024×1024 pixels.
2. Use appicon.co to generate your app icon set.
3. Place the generated icons in the correct asset directories as specified.
4. Run the following command:

flutter pub run flutter_launcher_icons:main
