I am trying to create a form in ionic 3 to send data from a form, the form contains an image and it is sent to an api-rest that I have listening to with flask, the case is that I do not know how to do this with ionic but I would be very useful, I have looked in Google but there is nothing clear about how to do it, so I see using the FormData is a good option but I do not know how to use it correctly to get the image and read it to send it along with the form, I would appreciate a little help to achieve this. thanks.
