To run a command in Dart, you need to use the Dart SDK which can be downloaded from the official Dart website. After installation, you can use either the command line or an IDE like Visual Studio Code to run your Dart code.
To run a Dart program from the command line, follow these steps:
1. Open the command prompt or terminal on your computer.
2. Navigate to the directory where your Dart program is saved using the cd command.
3. Once you are in the correct directory, type dart followed by the name of your program file and press Enter.
4. For example, if your program file is called hello_world.dart, you would type dart hello_world.dart followed by Enter.
Here's an example of a simple Dart program that prints "Hello, world!" to the console:
void main() {
print('Hello, world!');
}
To run this program in Dart, save it with the name hello_world.dart and type the following command in the command prompt or terminal:
dart hello_world.dart
This will execute the program and print "Hello, world!" to the console.
