join()
Converts each element to a String and concatenates the strings.
Iterates through elements of this iterable, converts each one to a String by calling Object.toString, and then concatenates the strings, with the
separator
string interleaved between the elements.
Example
void main() {
var parts = ['apple', 'banana', 'orange'];
var result = parts.join(', ');
print(result); // Output: apple, banana, orange
var one = ['jeet', 'sahil', 'keel'];
var answer = one.join(',' + ' '); // Uses a string
print(answer);
}
apple, banana, orange
jeet, sahil, keel
