[FREE / Open Source] - Dynamic Components Extension (for every component)

Hi, I want to introduce my new extension which allows creating components dynamically!

But, you may ask;
“There is an already bunch of different Dynamic Components extension, why did you create another one?”
Because this one is different!

I thought about making a full method to create all dynamic components without creating different blocks for every component because it would be useless. So I was trying to find a proper solution for a long time. And here it is!

It basically uses Java’s Reflection feature, so this allows you to create ANY component you want dynamically which added to App Inventor (includes Kodular components too if you use Kodular). Not only a Button, but you can also even create a DatePicker dynamically. Just type the component’s name which you want to create, that’s it! :star_struck:

What is the reflection and how does it work?

Reflection (in programming) allows you to modify the program during runtime, for example, you can create a new Class, Method, etc. and search them by its names!

Basically, it appends componentName parameter to the com.google.appinventor.components.runtime. text and creates an instance of it. When you type “Button”, it searches for Button class and creates an instance of it.

So with this method, it is now a fully implemented dynamic component extension.

I must say Java is a powerful language :grin:


Blocks

FAQ

  • How can I set the properties for the blocks?
    You have two options and both does the same job:

    • SetProperty

    • or Any Component
      image
  • How can I delete all components?
    Use a for-each loop for that.

Good Job! Way to go!

Excellent job @yusufcihan!!!
I’ll check it with the update to my brick breaker game and see how it handles creating 238 sprites for the bricks (The current version has 70 bricks total).
I know is a lot, but since they are all static, I think it will not be a problem.

You can’t in App Inventor (not Inverter) but you can in Kodular. With this extension you can create components at runtime instead of creating them in the designer. And you can change the properties of those dinamically generated components by using the Any component blocks.

Yep, it removes from layout (not hide) and removes its ID from created component list. So you can create a new component with same ID.

Yes. You need to use Any Component blocks for editing the components.

I love this reaction :rofl: Thank you! :smile:


By the way, thanks for your interest about this extension, you all made me happy! :blush: Let me know if you need another thing which is not implemented in App Inventor yet. I’d love to create new possibilities for everyone. :grin:
