It is an object-oriented, class-based language with a C-style syntax.

🔹 Understanding `main()` Function in Dart

The main() function is the entry point of every Dart program. When your app runs, Dart looks for this function and starts executing from there.

void main() {
  print('Hello, Dart!');
}

Code Breakdown:

void: This means the function doesn't return any value.
main(): The name of the entry function where your program starts.
print(): This function outputs text to the console.

📦 Where does `print()` show output?

When you run a Dart program, the print() output appears in the terminal or console.

In Flutter development (in VS Code or Android Studio), you can see this output in the Debug Console.

💡 What is a Terminal?

The Terminal (or Command Line) is a place where developers can run commands, execute code, and see output or errors.
