dart concatenate string
String a = 'a';
String b = 'b';
var c1 = a + b; // + operator
var c2 = '$a$b'; // string interpolation (prefered method)
var c3 = 'a' 'b'; // string literals separated only by whitespace are concatenated
var c4 = 'abcdefgh abcdefgh abcdefgh abcdefgh'
'abcdefgh abcdefgh abcdefgh abcdefgh';flutter string concatenation
var txn = {title: 'Amount Deducted', amount: 150};
var branchCode = 'ABD125';
print("Branch Code $branchCode"); // ABD125
print("\$ ${txn.amount}"); // $150
print("Total Amount Deducted: ${txn.amount}"); // Total Amount Deducted: 150concatenate in flutter
In dart there are many string options.
For concatenation, you can do :
'hello $myVariable'
"hello ${myVariable.myProperty}"
'hello ' 'world' (only works with string literals)
'hello' + myVariable
So in your case, you can do a print(" $str1 $str2")Copyright © 2021 Codeinu
