chooseImage & startUpload are not functions, if you created a function

void chooseImage() {
 // add image picking code here
}

then you need to change

onPressed: chooseImage,

to

onPressed: chooseImage(),

if you didn't make those functions you could also do

onPressed: () {
// add image picking code here
}
