I Took a variable in my State File? image;

Then Accesing image from my device

  void filePicker() async {
    final File? selectedImage =await ImagePicker.pickImage(source: ImageSource.gallery);
    print(selectedImage!.path);
    setState(() {
      image = selectedImage;
    });
  }

Then tyring to pass the image file along with other http body parameters. If I didn't pass the image file, then the API didn't show any error. But I need to pass the image file to get the correct result. As I Explicitly throw Exception, so its throwing exception like Faild to fetch and message in ScaffoldMessenger --> Somthing went wrong

 Future<void> SaveCustomTestBooking() async {
var jsonResponse;
if (EncUserId.isNotEmpty) {
  var postUri = Uri.parse("http://medbo.digitalicon.in/api/medboapi/SaveCustomTestBooking");
  var request = http.MultipartRequest('POST', postUri);
  request.fields['VisitDate'] = _selectedDate;
  request.fields['EncUserId'] = EncUserId;
  request.files.add(new http.MultipartFile.fromBytes('image',await File.fromUri(Uri.parse(image!.path)).readAsBytes(),contentType: new MediaType('image', 'jpeg')));

  request.send().then((response) {
    if (response.statusCode == 200) {
      print("Uploaded!");
      Navigator.push(context,MaterialPageRoute(builder: (context) => DieticianAfterDateSelectPage(rresponse:DieticianEncBookingIdModel.fromJson(jsonResponse),)));
    } else {
      ScaffoldMessenger.of(context)
          .showSnackBar(SnackBar(content: Text("Somthing went wrong")));
      throw Exception("Faild to fetch");
    }
  });
}

}

CodePudding user response：

You should use MultiPart post method. Take a look at this.

You can pass image file simply in this way:

   //header
   var headers = {
          'content-type': 'multipart/form-data',
          'Accept': 'application/json',
        };
   
   //setup request
    var request = http.MultipartRequest(
            "POST", Uri.parse("your api url"));
    
    //add files to reqest body
     request.files.add(await http.MultipartFile.fromPath(
          'your feild name',
          pickedFile.path,
        ));
   
    //add header
    request.headers.addAll(headers);

    //send request and return response
        try {
          var streamedResponse = await request.send();
          var response = http.Response.fromStream(streamedResponse);
          return response;
        } catch (e) {
          rethrow;
        }
      }
