Answer 1

This can be easily made with the Dio package.

https://pub.dartlang.org/packages/dio

Update

Based on the new Dio API:

var dio = Dio();
dio.interceptors.add(InterceptorsWrapper(onRequest: (RequestOptions options) async {
  var customHeaders = {
    'content-type': 'application/json'
    // other headers
  };
  options.headers.addAll(customHeaders);
  return options;
}));

Response response = await dio.get("url");
print(response.data.toString());

Refer the documentation for more details.
