Issue Description and Steps

How do I send an array of queryParameters?

In postman, I am able to send a GET with an array of parameters. The URL looks like this and it works fine:

/v2/tickets?templateId=5&templateId=7

I have tried a lot of different ways to do the same in flutter with Dio and can't get it to work:

queryParameters['templateId'] = [1, 2];
queryParameters['templateId'] = ['1', '2'];
queryParameters['templateId'] = `[1, 2]`;

  var uri = Uri(
    ...
    queryParameters: {
      "templateId": ['1', '2']
    },
  );
  dio.getUri(uri);

[MilesAdamson]

  var uri = Uri(
    ...
    queryParameters: {
      "templateId": ['1', '2']
    },
  );
  dio.getUri(uri);

Thank you, works perfectly. The issue was I was using dio.get() instead of dio.getUri()

I'm facing this error too, I just want to send a simple int list but can't

[wizetLee]

queryParameters: {
   "templateId[]": ['1', '2']
}

This format helped me solve this problem

It doesn't work with dio.request method. There are multiple keys with different value from list when dio sends requests

For example:

final _queryParameters = <String, dynamic>{
"categoriesIn": [1,2,3]
}

final response = await dio.request<Object>(path, queryParameters: _queryParameters ....);

When it calls the api I notice that it uses path?categoriesIn=1&categoriesIn=2 instead of path?categoriesIn=1,2
