Вивчайте Print Function in Dart | First Acquaintance with Dart

To display information in the console, add text inside the parentheses of the print() function.

main.dart


              123
            
void main() {
  print("Text you want to output");
}

If you want to output the text to the console, we must write it inside the quotation marks.

main.dart


              123456
            
void main() {
  // The text can be written in single quotation marks
  print('Hi, Codefinity!');
  // The text also can be written in double quotation marks
  print("I want know more");
}

The main rule when using the print() function is that it's important for the quotation marks surrounding the text to match on both sides. For example, if we use single quotes to print text ('like this'), we must close them with single quotes as well. This allows Dart to correctly recognize it as text to be printed, rather than a variable name or instruction. If the quotation marks do not match, or if they are absent altogether, it can lead to a runtime error in the program.

main.dart


              123
            
void main() { 
  print(2);   
}

Working with numbers differs from working with text. When displaying numbers, you don’t need to use quotes (" " or ' '), because numbers are treated as numeric values, not text.
