}
}
Command Line to build the project.
Windows: make-windows.bat
Linux: bash make-linux.sh

Event Handling
There are two ways to handle event:
- By Lambda Method
- By Static Method
// 1. Lambda Method
setAction("love-button", e -> showLove(e));
// 2. Static Method
setAction("love-button", Start::showLove);Sample Code
