withQueryParameters method

Uri withQueryParameters(Map<String, Object?> parameters)

Returns a copy with the supplied query parameters merged into the existing query parameters.

Passing null removes a key.

Implementation

Uri withQueryParameters(
  Map<String, Object?> parameters,
) {
  final merged = <String, String>{
    ...queryParameters,
  };

  for (final entry in parameters.entries) {
    final value = entry.value;

    if (value == null) {
      merged.remove(entry.key);
    } else {
      merged[entry.key] = value.toString();
    }
  }

  return replace(
    queryParameters: merged.isEmpty ? null : merged,
  );
}
