[Request Feature] Add Query param to Options about dio

[wendux]

you can use TransFormer.urlEncodeMap(queryMap) directly:

var queryMap={
  'search': 'How to become a hero like LyNam'
}；
var result = await dio.post('$url?${TransFormer.urlEncodeMap(queryMap)}',....);

yes, we can process the string, but if dio can support, that will be simpler and safer by parse from URI in dio core

var uri = Uri.http('http://demo.com/api', '/search', {
      'search': 'how can...'
    });

it relate to baseUrl and should be did in dio core.

I known, you can also :

var uri=Uri(scheme: "https", host: "flutterchina.club", queryParameters: {
    "xx":"xx",
    "yy":"dd"
  });
var result = await dio.post(uri.toString(),....)

I personally think that creating an Uri instance is not easy and most of the time, the user has only a url link（String）。 so, dio support url which type is String default. when the users need an Uri, they can also create it manually, and then call toString() method to pass the result to the APIs of dio, It's very simple, isn't it。

i remember i did like that, but the url be dupplicate with something like:

http://demo.com/http://demo.com/...........

i think dio has not handled full url like that yet.
ps: this i added baseurl to dio, and other case i have not done yet

If the path starts with "http:" or "https:", the baseUrl will be ignored. This feature will not be supported. Thanks !
