urlEncodeMap method Null safety

String urlEncodeMap(
  1. Map map,
  2. [ListFormat listFormat = ListFormat.multi]
)

Deep encode the Map<String, dynamic> to percent-encoding. It is mostly used with the "application/x-www-form-urlencoded" content-type.

Implementation

static String urlEncodeMap(
  Map map, [
  ListFormat listFormat = ListFormat.multi,
]) {
  return encodeMap(map, (key, value) {
    if (value == null) return key;
    return '$key=${Uri.encodeQueryComponent(value.toString())}';
  }, listFormat: listFormat);
}
