addParameter method

void addParameter(
  1. String name,
  2. String value
)

Adds value to the query parameter name of uri (the values already there stay).

Implementation

void addParameter(String name, String value) {
  final all = {
    for (final entry in uri.queryParametersAll.entries)
      entry.key: [...entry.value],
  };
  (all[name] ??= []).add(value);
  uri = uri.replace(queryParameters: all);
}
