This is my payload:

final Map<String, dynamic> registration = {
        'company_name': _companyName,
        'team_name': _teamName,
        'image': _image
      };

company_name and team_name are string as expected. However, _image is defined like below:

File _image;

So when I do the post request I am getting the below error on terminal:

type '_File' is not a subtype of type 'String' in type cast

I know this is happening because I defined registration as <String, dynamic>. How to fix this?

where do you want to send the image? – diegoveloper Dec 18 '18 at 18:01
To an API endpoint using http.post() (note: I control the API as well) – Jithesh Kt Dec 18 '18 at 18:11
