I am trying using file_picker and dio packages to upload files as form data.
This is for flutter web and it seems MultipartFile.fromFile
is not accepted.
What I tried is the following:
if (result != null) {
for (var file in result.files) {
final formData = FormData.fromMap({
...someOtherData,
'file': File(file.name), // <------ I guess this is where the issue is, I also tried file instead of File(file.name)
});
dio.post(
url,
data: formData,
);
}
}
If anyone is still wondering how to get it working on both mobile and web (This is using the image_picker's PickedFile as the image variable type):
FormData body;
final bytes = await image.readAsBytes();
final MultipartFile file = MultipartFile.fromBytes(bytes, filename: "picture");
MapEntry<String, MultipartFile> imageEntry = MapEntry("image", file);
body.files.add(imageEntry);
** The catch is that the filename is required on web and is automatically assigned on mobile.**
Ok, I found it, leaving here for someone having the same problem
if (result != null) {
for (var file in result.files) {
final formData = FormData.fromMap({
...someOtherData,
'file': MultipartFile.fromBytes(file.bytes as List<int>)
});
dio.post(
url,
data: formData,
);
}
}
