request.uri have a different query parameter order than response.realUri and response.requestOptions.uri

The test passes.

test('Query parameters equality', () async {
  final dio = Dio()
    ..httpClientAdapter = EchoAdapter()
    ..options.baseUrl = EchoAdapter.mockBase;
  const queryParameters = <String, String>{'a': '1', 'b': '2'};
  final response = await dio.get(
    '/test',
    queryParameters: queryParameters,
  );
  expect(
    response.realUri.queryParameters.toString(),
    equals(response.requestOptions.queryParameters.toString()),
  );
});

@AlexV525 I updated the title since it was incorrect, apologies.

Here is what's happening for us:

Uri we input: /tracks?range=months&orderBy=TIME
Response output: /tracks?orderBy=TIME&range=months

[AlexV525]

test('Query parameters equality', () async {
  final dio = Dio()..httpClientAdapter = EchoAdapter();
  final uri = Uri.base.resolve(
    '${EchoAdapter.mockBase}/test?range=months&orderBy=TIME',
  );
  final response = await dio.getUri(uri);
  expect(
    response.realUri.queryParameters.toString(),
    equals(response.requestOptions.uri.queryParameters.toString()),
  );
});

@AlexV525 You are testing the uri's in the response object. Those are both the same, It's the uri in dio.getUri(uri); and the response object uri's that have the different query parameter order.

test('Query parameters equality', () async {
  final dio = Dio()..httpClientAdapter = EchoAdapter();
  final uri = Uri.base.resolve(
    '${EchoAdapter.mockBase}/test?range=months&orderBy=TIME',
  );
  final response = await dio.getUri(uri);
  expect(
    response.realUri.queryParameters.toString(),
    equals(uri.queryParameters.toString()),
  );
});

Since we copy the query parameter map in a couple places this might be possible but you need to provide a reproducible example.

Please attach a reproducible example so we may take further investigations.
