Flutter: FutureBuilder How can I load a future that receives arguments? - flutter

Question

I am working with a FutureBuider and I don't know how I can load a Future that receives an argument. I get an error, the future is in an external file 'provider.dart', I attach an image of the error:
1 positional argument(s) expected, but 0 found.
Try adding the missing arguments.dart(not_enough_positional_arguments)
To explain myself better I have to mention the structure of the application:
HomePage: in it you select an image that will be sent to a 'provider.dart' file.
PhotoPage: On this page, a value obtained from the Provider.dart file is obtained through a FutureBuilder, as shown in the image above.
children: [
FutureBuilder(
future: fotoProvider.uploadImageCloudinary(),
builder: (context, AsyncSnapshot<String> snapshot) {
if (snapshot.hasError) {
return Center(
child: Text('ERROR: ${snapshot.error.toString()}'),
);
}
if (!snapshot.hasData) {
return Center(
child: CircularProgressIndicator(),
);
}
return Center(
// I WOULD LIKE TO PRESENT THE RESULTS OF THE SECOND FUTURE HERE
child: Text(snapshot.data),
);
},
),
],
),
Provider.dart: There are two Future's:
1 Future: It receives the image from the home and processes it sending it to the Cloudinary API, I get the url generated by Cloudinary to be sent to the second Future.
Future<String> uploadImageCloudinary(File imagen) async {
final url = Uri.parse('https://api.cloudinary.com/...');
final mimeType = mime(imagen.path).split('/'); // Image/jpeg
final imageUploadRequest = http.MultipartRequest('POST', url);
final file = await http.MultipartFile.fromPath(
'file',
imagen.path,
contentType: MediaType(mimeType[0], mimeType[1]),
);
imageUploadRequest.files.add(file);
// execute request
final streamResponse = await imageUploadRequest.send();
final resp = await http.Response.fromStream(streamResponse);
if (resp.statusCode != 200 && resp.statusCode != 201) {
print('Something went wrong');
print(resp.body); // Error
return null;
}
dynamic respData = json.decode(resp.body);
print(respData);
urlGenCloudinary = respData['secure_url'];
// Shipment to the second future
return await requestSecondAPI(urlGenCloudinary);
}
2 Future: It receives the url and sends it to another API, this one processes it and generates a String that is the data that I want to be sent to FutureBuilder in FotoPage.
Future requestSecondAPI(String url) async {
final String apiUrl =
"https://api...";
final res = await http.post(
Uri.parse(apiUrl),
headers: {
"Content-type": "application/json",
"Authorization": "Key "
},
body: jsonEncode({
"inputs": [
{
"data": {
"image": {'url': url}
}
}
],
"model": {
"output_info": {
"output_config": {"max_concepts": 40, "min_value": 0.8}
}
}
}),
);
final resReqRes = reqResRespuestaFromJson(res.body);
String resultado = resReqRes.outputs[0].data.concepts[0].id;
return resultado;
}
Thank you in advance.
I tried to place the second Future in the FutureBuilder and I get the following errors:
In FutureBuilder:
"Couldn't infer type parameter 'T'. "
In the future within the FutureBuilder:
"1 positional argument(s) expected, but 0 found.
Try adding the missing arguments."
In the builder:
"The argument type 'Center Function(BuildContext, AsyncSnapshot)' can't be assigned to the parameter type 'Widget Function(BuildContext, AsyncSnapshot)' "
