2. Add the Brick: Use the mason add command to add the brick to your project:

   Copy
   1mason add login_screen --git-url https://github.com/your/brick-repository.git

   This command adds the login_screen brick from the specified Git repository to your project's mason.yaml, making it ready for use.

3. Generate Code: With the brick added, generate the login screen using:

   Copy
   1mason make login_screen

   This command creates all the necessary files and code for the login screen in your project, following the structure defined in the brick template.

Creating Your First Custom Brick

While using existing bricks is convenient, creating your own custom bricks can significantly boost your productivity. Here's a quick guide to creating your first custom brick:

1. Define the Brick: Create a new directory for your brick, say custom_widget, and inside it, create a brick.yaml file. This file describes your brick, including its variables and templates.
2. Create Templates: Inside the custom_widget directory, add your template files. Use double curly braces {{variable_name}} to mark places where dynamic content will be inserted in your templates.
3. Add and Use Your Brick: Once your custom brick is ready, add it to your project using mason add with the path to your brick directory. Then, generate code with mason make custom_widget, customizing the output with your specified variables.

Mason Brick for Folder Structure: Best Practices
