flutter string concatenation

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';

                                    In dart there are many string options.

For concatenation, you can do :

    'hello $myVariable'
    &quot;hello ${myVariable.myProperty}&quot;
    'hello ' 'world' (only works with string literals)
    'hello' + myVariable

So in your case, you can do a print(&quot; $str1 $str2&quot;)

Thank you! 5

                                    var txn = {title: 'Amount Deducted', amount: 150};
var branchCode = 'ABD125';

print(&quot;Branch Code $branchCode&quot;); // ABD125
print(&quot;\$ ${txn.amount}&quot;); // $150
print(&quot;Total Amount Deducted: ${txn.amount}&quot;); // Total Amount Deducted: 150

Thank you! 6
