Uploading Image to an Api

[abdul-sh]

Hello there,
I wanna thank u for the hard work u have invested to build this Flutter package so many people can get benefit from it. I was trying to upload an image to the api but I did not know how to make this work. Can u please give me an example for that. Thank u in advance.
This is what I have done:

NTLMClient client = NTLMClient(
domain: "",
workstation: "LAPTOP",
username: "username",
password: "password",
);
await client
.post(
Uri.parse(
'https://someWebsite/'),
body: File('imagePath').toString(),
)
.then((res) {
print(res.body);
});

But it did not seem to work.
