Part 2: How to Create Your FIRST Extension: Custom UI for App Inventor, Kodular & Niotron

Описание: Ready to bring your ideas to life? In Part 2 of our extension development series, we dive into the code and create our very first, genuinely useful extension: a custom Arrangement Styler!

Following our environment setup in Part 1, this video guides you step-by-step through writing the Java code for a powerful function. This extension will allow you to add rounded corners, custom borders, and unique background colors to any Vertical or Horizontal Arrangement in App Inventor, Kodular, and Niotron—a feature many developers need!

By the end of this tutorial, you will not only have a working extension but also a solid understanding of how to create functions, handle parameters, and bring your custom logic into the blocks editor.
