The API I'm fetching returns json value like this. I wrote the following code to extract the data, it works if I code it like this and the widget builds, but with this error before the widget loads
Future getJsonData() async{
var response;
for(int i=1; i<=5; i++){
response = await http.get(
Uri.encodeFull(widget.api+i.toString()),
headers: {"Accept": "application/json"}
);
setState(() {
var toJsonData = json.decode(response.body);
item.addAll(toJsonData['hits']);
});
}
print(response.body);
return item;
}
error image
But when I use FutureBuilder method, it fails to create the widget. It would be helpful if someone can tell a possibly working FutureBuilder method for this json data.

How to get some Specific data from Restapi [flutter]

I want to get only those item which contain type Lunch `` This is a function where I can fetch data from Rest Api and also ApiResponse added
I need to get specific data from a session I send instead of getting the entire array from the response from the Api() method. How do I capture just the only those item which contain type Lunch from the array?

if (response.statusCode == 200) {
products.clear();
ProductsModel.fromJson(response.data);
products.add(ProductsModel.fromJson(response.data));
if (query != null) {

}
}
} on DioError catch (e) {

If the response status code returns 200 after making a request with the rest api, assign the data in it to a variable of the type of your model, then you can get it from the variable as you want.

How to get Image URL based on name

My JSON contains only name of the food categories, Looks like below
[
{
"cu_id": "2",
"cuisine_type": "American"
},
{
"cu_id": "24",
"cuisine_type": "Sandwich"
},
{
"cu_id": "17",
"cuisine_type": "Seafood"
},
{
"cu_id": "29",
"cuisine_type": "Sports Bar"
},
{
"cu_id": "5",
"cuisine_type": "Steak"
},
{
"cu_id": "20",
"cuisine_type": "Sushi"
}
]
I want to get default image automatically from Internet by searching 'cuisine_type', How to do that?

You can use pixabay api it's a free RESTful api for searching and retrieving free images and videos released on Pixabay under Creative Commons CC0.
Sending a GET request like this :
https://pixabay.com/api/?key={ KEY }&q=query&image_type=photo
where :
Key : the api key you get after creating an account
q : the queried object you need to look for
image_type : what kind of data you need (picture, video)
returned data will be something like this :

Json parsing in skyscanner pricing api

I started working with sky-scanner API using volley on Android. I am able to poll the response from the API, however I have no clue how to parse the json which is sent in response, please see json below. The json response is very big, I have never worked with such responses before thus have no idea how can I handle this.
Can someone please help me figure this out? There is no sample implementation done by anyone for skyscanner for android.
JSON response to be parsed to get price, agents, flight number, carrier, duration of flight, image URL of flight.

P.S. I hope this will helps you the idea how to get the data you need.

I'll show a basic example of how to parse. Take the following sample JSON.
http://api.androidhive.info/contacts/
How to get the contacts list.
JSONObject jsonObj = new JSONObject("Your JSON String here");
JSONArray contacts = jsonObj.optJSONArray("contacts");
How to calculate the phone number
//Get first contact
JSONObject firstContact = contacts.optJSONObject(0);
JSONObject phone = firstContact.optJSONObject("phone");
String mobileNo = phone.optString("mobile");
Similarly you can apply this technique to your JSON.

There is a many to many relationship between users and groups.
I am using retrofit with the GsonConverterFactory. On response, how can I parse this information into objects?
I tried making a User class , and a group class, then I put an array of groups as a member of the user class.
But when I access User.getGroups().get(1).getID , it returns 0.
However, User.getGroups().size() does return 4 (the correct number in this case)
How can I achieve this in retrofit?

A practical tool to parse JSON correctly with retrofit can be to generate the classes with http://www.jsonschema2pojo.org
You just have to put the example JSON, the resource type in JSON and put the desired annotation style (GSON, Jackson, ..).

==>> I am using the code below to get JSONArray:
Response response = client.newCall(request).execute();
//here I am getting the json response(mentioned above) from wordpress rest api
String json = response.body().string();
JSONObject object = new JSONObject(json);
//Below code is giving me null array as I dont have "Array name" in my json response.
JSONArray array = object.optJSONArray("Name of Array in json response");
Please help me get JSONArray out of json response.

Looking at your JSON string, it seems that the entire response body is a JSON-Array, so you can simply parse it directly into a instance of JSONArray.
This is how you can do it:
//get your JSON body-string like you do
String json = response.body().string();
//parse it directly into JSONArray
JSONArray array = new JSONArray(json);
//do whatever you want with the array...
I hope this helps you.
