I am new to Dart programming language and anyone help me find the best string concatenation methods available in Dart.
I only found the plus (+) operator to concatenate strings like other programming languages.

You can concatenate String with other type of objects. All you need to do is convert the other type of Dart object to String using object. toString() method. In this example, we will take a String and an int and concatenate them using + .
String interpolation is the process of inserting variable values into placeholders in a string literal. To concatenate strings in Dart, we can utilize string interpolation. We use the ＄{} symbol to implement string interpolation in your code.
Type Syntaxvar name = 'Smith'; All variables in dart store a reference to the value rather than containing the value. The variable called name contains a reference to a String object with a value of “Smith”.
There are 3 ways to concatenate strings
String a = 'a'; String b = 'b'; var c1 = a + b; // + operator var c2 = '$a$b'; // string interpolation var c3 = 'a' 'b'; // string literals separated only by whitespace are concatenated automatically var c4 = 'abcdefgh abcdefgh abcdefgh abcdefgh' 'abcdefgh abcdefgh abcdefgh abcdefgh'; Usually string interpolation is preferred over the + operator.
There is also StringBuffer for more complex and performant string building.
