Dart: String

String  variable_name = 'value'  

//OR  

String  variable_name = ''value''  

//OR  

String  variable_name = '''line1 
line2'''  

//OR  

String  variable_name= """line1 
line2"""

Example

void main() { 
   String str1 = 'hello'; 
   String str2 = "hello"; 
   String str3 = '''hello world'''; 
   String str4 = """hello world"""; 
   
   print(str1);
   print(str2); 
   print(str3); 
   print(str4); 
}

It will produce the following Output −

hello 
hello 
hello world 
hello world 

# String Interpolation

void main() { 
   String str1 = "hello"; 
   String str2 = "world"; 
   String res = str1 +str2; 
   
   print("The concatenated string : ${res}"); 
}

=> output

The concatenated string : Hello world
