Strings.join removed in M3 - what is new syntax?

Question

The code below no longer works in Dart M3, and I couldn't find what the new syntax is.

Could someone please advise?

#import('dart:uri');

String encodeMap(Map data) {
  return Strings.join(data.getKeys().map((k) {
    return "${encodeUriComponent(k)}=${encodeUriComponent(data[k])}";
  }), "&");
}

Answer 1

Simply use .join(separator) on Iterable.

In your case :

import 'dart:uri';

String encodeMap(Map data) {
  return data.keys.map((k) {
    return "${encodeUriComponent(k)}=${encodeUriComponent(data[k])}";
  }).join("&");
}

From Breaking Change: Strings class is going away :

The Strings class (note the trailing "s") in core is going away.
If you used Strings.join(stringIterable, separator) replace it with stringIterable.join(separator).
If you used Strings.concatAll(stringIterable) replace it with stringIterable.join().
