In this example we will declare string and later on put some value in it. Once we have value in the our string variable we will print their value.

main.dart

void main(){
    String website;
    website = "nstack";
    print(website);
}

void main(){
    String website = "nstack";
    print(website);
}

There is one mathematics operation which could be applied to String which is adding of two String.

Adding two String #

Adding of two string means putting one string after other. We usually don’t call it as adding of string but here I am calling it. I am calling adding of two string because it is being done use mathematical +(Add) Symbol.

main.dart

void main(){
    String website = "nstack";
    String tld = ".in";
    String url = website + tld;
    print(url);
}

The more appropriate term for adding string is Concat of String.
