// My IPv4 : 192.168.43.171 
final String phpEndPoint = 'http://192.168.43.171/phpAPI/image.php';
final String nodeEndPoint = 'http://192.168.43.171:3000/image';
File file;

 void _choose() async {
   file = await ImagePicker.pickImage(source: ImageSource.camera);
// file = await ImagePicker.pickImage(source: ImageSource.gallery);
 }

 void _upload() {
   if (file == null) return;
   String base64Image = base64Encode(file.readAsBytesSync());
   String fileName = file.path.split("/").last;

   http.post(phpEndPoint, body: {
     "image": base64Image,
     "name": fileName,
   }).then((res) {
     print(res.statusCode);
   }).catchError((err) {
     print(err);
   });
 }
